RESUMO

BACKGROUND/AIM: Ovarian carcinoma is the fifth leading cause of cancer-related deaths in women in the United States. Serous papillary carcinoma is the most common histological type of ovarian carcinoma that often goes undetected until it has spread within the pelvis and abdomen leading to poor prognosis. Translation of next-generation sequencing (NGS) technology into personalized medicine and identification of new potential targets for therapeutic applications may be helpful. CASE REPORT: We report a case of a 59-year-old female who initially presented in the emergency department with increasing abdominal girth, and bloating. Computed tomography showed ascites and omental and pelvic masses. Fine needle biopsy of the omental mass showed high-grade papillary adenocarcinoma consistent with high-grade ovarian serous carcinoma. She was treated with chemotherapy followed by debulking surgery. Primary ovarian serous carcinoma and synchronous primary fallopian tube serous carcinoma with multiple leiomyomas were identified in the surgical specimen. Pleural biopsy was also positive for carcinoma. NGS and programmed death-ligand 1 (PD-L1) expression testing were performed in the ovarian serous carcinoma. The results showed mutations of breast cancer type 1 (BRCA1) and type 2 (BRCA2), tumor protein p53 (TP53) (c.524G>A at pR175H), and heat shock protein 90 alpha family class B member 1 (HSP90AB1) (p.R456C), as well as low RNA expression score of PD-L1. CONCLUSION: Identification of these mutations and PD-L1 abnormality at the diagnosis of ovarian carcinoma may shed light for clinicians to provide targeted therapy with poly (ADP-ribose) polymerase (PARP) inhibitors and immune checkpoint inhibitors for ovarian serous carcinoma. This is the first documented case of ovarian serous carcinoma to have found a HSP90AB1 (p.R456C) mutation.

RESUMO

OBJECTIVE: Treatment and follow-up are controversial in patients whose thyroid fine needle aspiration biopsy (FNAB) is reported as atypia of undetermined significance and follicular lesion of uncertain significance (AUS/FLUS). We aimed the efficacy of the American College of Radiology Thyroid Imaging, Reporting and Data System (ACR TI-RADS) in preventing unnecessary thyroidectomies in patients with FNA cytology results as AUS/FLUS. METHODS: In Bolu Abant Izzet Baysal University General Surgery Clinic, case series between 2017 and 2020 were analyzed with thyroid operated. Grouping was made according to the result of postoperative pathology: those with benign results after postoperative pathology were classified as Group 1, and those with malignant results after postoperative pathology were classified as Group 2. RESULTS: As a result, 66 patients were found to be AUS/FLUS. A total of 28.8% of AUS/FLUS patients have been determined with cancer. In the statistical analysis of the ACR TI-RADS score between the groups, the ACR TI-RADS score in Group 1 patients (3.36) (SD 0.87) was significantly lower than that in Group 2 patients (4.11) (SD 1.04) (p=0.003). The distribution of the ACR TI-RADS scores of the patients in Group 2 was TR2: 2 (15.4%) patients, TR3: 3 (25%) patients, TR4: 5 (16.1%), TR5: 9 (90%) patients, respectively. CONCLUSION: The ACR TI-RADS score was statistically significant in predicting malignancy in AUS/FLUS patients whose follow-ups and treatments are controversial, and the ACR TI-RADS has a limited role in preventing unnecessary thyroidectomies in patients with AUS/FLUS.

RESUMO

INTRODUCTION: Lateral neck masses present clinically as neoplastic or non-neoplastic lesions of lymph nodes, salivary glands, and thyroid. Non-neoplastic lesions, if evaluated timely, may not transform into malignancy thus reducing clinical burden. A cytomorphological study using fine needle aspiration is a reliable method for the diagnosis of such masses. The aim of this study was to find out the prevalence of non-neoplastic lesions of lateral neck mass specimens received in the Department of Pathology in a tertiary care center. METHODS: This descriptive cross-sectional study was carried out in the Department of Pathology among lateral neck mass specimens of a tertiary care center from January 2019 to December 2020 after obtaining ethical approval from the Institutional Review Committee (Reference no: 155/19). A convenience sampling method was used and data analysis was done in Microsoft Excel 2019. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS: Out of 300 lateral neck mass specimens, non-neoplastic lesions were found in 246 (82%) (77.7-86.3 at 95% Confidence Interval). The involvement of lymph nodes in 117 (47.6%) was the most common finding followed by thyroid 112 (45.5%). Among non-neoplastic lesions, the cytomorphological features of benign nodular goiter 93 (37.8%) was the most common lesion followed by reactive lymphoid hyperplasia 73 (29.7%). CONCLUSIONS: The study showed that the prevalence of non-neoplastic lesions was similar to that of other national and international studies.

RESUMO

Background and Objectives: It is necessary to properly diagnose and manage axillary lymphadenopathy caused by a variety of diseases. This study aimed to evaluate the utility of ultrasound (US)-guided sampling in patients with axillary lymphadenopathy. Materials and Methods: Patients with axillary lymphadenopathy (excluding patients with newly diagnosed breast cancer) who underwent US-guided fine needle aspiration (FNA) or core needle biopsy (CNB) at a single center between February 2016 and September 2020 were retrospectively examined. The association between US imaging findings and malignancy was investigated and the diagnostic performance of US-guided sampling was assessed. Results: Fifty-five patients (including eight males) were included in the study; of these, 34 patients (61.8%) were finally diagnosed with a malignant lymph node lesion. Twenty-two patients (40.0%) had undergone FNA and 33 (60.0%) had undergone CNB. Larger short and long axis diameters, thicker lymph node cortex, and the absence of fatty hilum on the US were significantly associated with malignancy (p < 0.05). The diagnostic performance of FNA, CNB, and FNA + CNB was excellent (sensitivity, specificity, and accuracy of 0.909, 0.900, and 0.917 for FNA, 0.958, 1.000, and 0.970 for CNB, and 0.941, 0.952, and 0.945 for FNA + CNB, respectively). Conclusions: US-guided FNA and CNB play an important role in the diagnosis and management of patients with axillary lymphadenopathy.

RESUMO

We report a case of ectopic cervical thymoma that was difficult to differentiate from thyroid tumor. A 69-year-old woman was referred to our hospital with a tumor on the left side of the neck. Fine-needle aspiration cytology could not establish the diagnosis and the surgery was then performed for diagnosis and treatment. Since the intraoperative pathological diagnosis was also inconclusive, thymectomy was performed because of the macroscopic finding suggesting close relation to the thymus. The final pathological diagnosis was type AB thymoma.

RESUMO

To evaluate the usefulness of intraoperative pathology (IP) in thyroid surgery, a retrospective review of its results in 350 patients was performed in comparison with the results of the preoperative fine-needle biopsy (FNB) and the surgical pathology report (SPR). The FNB was reported according to the Bethesda system as type II in 91 cases (26.0%), type III in 21 (6.0%), type IV in 73 (21.9%), type V in 54 (15.4%), and type VI in 111 (31.7%). The IP showed benign lesions in 137 cases (39.1%), malignancy in 169 (48.2%), and inconclusive results in 44 (12.6%). The SPR results were benign pathology in 161 cases (46%) and carcinoma in 189 (54%); carcinoma was found in 8 patients (5.8%) in whom the IP had reported benignity, and in 12 (27.2%) with IP inconclusive results; 13 of those 20 cases were incidental microcarcinomas. The IP did not report any false positive result (specificity 100 %, sensitivity 89.4%, positive predictive value 100%, negative predictive value 90.0%, and accuracy 94.2%). When discriminated by Bethesda types, the malignant lesions detected by IP and SPR were, respectively: II 3 (3.3%) and 7 (7.70%); III 8 (38.1%) and 10 (47.6%); IV 3 (4.1%) and 10 (13.7%); V 47 (87.0%) and 52 (96.3%); VI 108 (97.3%) and 110 (99.1%). In most cases, the IP did not provide additional information to the FNB report nor did it detect microcarcinomas in others, so it does not seem justified to perform it routinely.

RESUMO

Neck masses are common physical examination findings seen in the outpatient setting but identifying an underlying cause can be challenging. A careful medical history should be obtained, and a thorough physical examination should be performed, which will guide the need for follow-up examination with imaging, biopsies, and specialist referrals. The goal of this article is to provide a working framework to evaluate and manage some of the most common causes of adult neck masses.

RESUMO

OBJECTIVE: The aim of the study was to investigate the mutation status of multiple driver genes by RT-qPCR and their significance in advanced lung adenocarcinoma using cytological specimens. MATERIALS AND METHODS: 155 cytological specimens that had been diagnosed with lung adenocarcinoma in the Fourth Hospital of Hebei Medical University were selected from April to November 2019. The cytological specimens included serous cavity effusion and fine-needle aspiration biopsies. Among cytological specimens, 108 cases were processed by using the cell block method (CBM), and 47 cases were processed by the disposable membrane cell collector method (MCM) before DNA/RNA extraction. Ten drive genes of EGFR, ALK, ROS1, BRAF, KRAS, NRAS, HER2, RET, PIK3CA, and MET were combined detected at one step by the amplification refractory mutation system and ABI 7500 RT-qPCR. RESULTS: The purity of RNA (p = 0.005) and DNA (p = 0.001) extracted by using the MCM was both significantly higher than that extracted by using the CBM. Forty-seven cases of fresh cell specimens processed by the MCM all succeeded in multigene detections, while of 108 specimens processed by the CBM, 6 cases failed in multigene detections. Among 149 specimens, single-gene mutation rates of EGFR, ALK, ROS1, RET, HER2, MET, KRAS, NRAS, BRAF, and PIK3CA mutations were 57.71%, 6.04%, 3.36%, 2.68%, 2.01%, 2.01%, 1.34%, 0.67%, 0% and 0% respectively, and 6 cases including 2 coexistence mutations. We found that mutation status was correlated with gender (p = 0.047), but not correlated with age (p = 0.141) and smoking status (p = 0.083). We found that the EGFR mutation status was correlated with gender (p = 0.003), age (p = 0.015) and smoking habits (p = 0.007), and ALK mutation status was correlated with age (p = 0.002). CONCLUSION: Compared with the CBM, the MCM can improve the efficiency of DNA/RNA extraction and PCR amplification by removing impurities and enriching tumor cells. And we speculate that the successful detection rate of fresh cytological specimens was higher than that of paraffin-embedded specimens. EGFR, ALK, and ROS1 mutations were the main driver mutations in patients with advanced lung adenocarcinoma. We speculate that EGFR and ALK are more prone to concomitant mutations, respectively. Targeted therapies for patients with coexisting mutations need further study.

RESUMO

INTRODUCTION: There are few studies on the role of puncture feeling in thyroid nodules during ultrasound-guided fine-needle aspiration cytology (US-FNAC), although it is expected to become a new predictive technique. We aimed to analyze the importance of puncture feeling in combination with US-FNAC and investigate whether it can be used as an indicator to predict the nature of thyroid nodules. MATERIALS AND METHODS: From January 1, 2018, to October 31, 2020, a total of 623 thyroid nodules were included. Puncture feeling was classified as "soft," "hard," or "hard with grittiness." The correlation between puncture feeling and postoperative pathology and the diagnostic value of FNAC combined with puncture feeling were analyzed, and the influence of thyroid nodule size on puncture feeling, FNAC, and FNAC combined with puncture feeling was studied. We further explored the correlation between puncture feeling and histopathology in Bethesda III and IV thyroid nodules. RESULTS: There was a significant correlation between puncture feeling and postoperative pathology (p < 0.001). The sensitivity, negative predictive value, and total coincidence rate of US-FNAC combined with puncture feeling for the diagnosis of thyroid nodules were higher than those of US-FNAC alone (96.1, 83.6, and 94.7% vs. 89.0, 65.5, and 89.7%, respectively). Thyroid nodule size was the influencing factor for puncture feeling, FNAC, and FNAC combined with puncture feeling (p < 0.05 for all). The area under the curve for puncture feeling, FNAC, and FNAC combined with puncture feeling for thyroid nodules of size ≤1 cm was greater than for modules of size >1 cm. Puncture feeling was of great value in diagnosing Bethesda III thyroid nodules (p < 0.001), and all Bethesda IV thyroid nodules had puncture feeling of soft. CONCLUSION: Puncture feeling is of great value during US-FNAC. "Hard" and "hard with grittiness" were indicators for malignancy, while "soft" indicated that the thyroid nodule was likely to be benign. The diagnostic value of US-FNAC combined with puncture feeling for thyroid nodules is higher than US-FNAC alone, especially when nodule size is ≤1 cm. Puncture feeling is of great value in predicting the nature of Bethesda III thyroid nodules.

RESUMO

Introducción: Los nódulos tiroideos se presentan entre el 4 al 8 % de la población, de los cuales hasta el 15% tienen etiología neoplásica. Las nódulos sospechosos de malignidad requieren la realización de punción, aspiración con aguja fina (PAAF) y la citología maligna reportada mediante sistema Bethesda tiene que ser corroborada con el estudio anatomopatólógico una vez realizada la excisión nodular. El objetivo del presente estudio es presentar la experiencia de un centro de referencia de pacientes con nódulos tiroideos. Metodología: Se realizó un estudio descriptivo, transversal, retrospectivo en el Servicio de Endocrinología del Hospital General del Norte de Guayaquil IESS CEIBOS, desde Junio 2017 a Julio 2019. El Universo estuvo compuesto por todos los casos con diagnóstico de nódulo tiroideo que requirieron PAAF. Se utiliza en sistema Bethesda para los reportes. Resultados: Fueron 349 casos de pacientes con nódulos tiroideos, mujeres (89%), edad entre 60 ­ 69 años (26%). 71 casos (21%) BETHESDA I; 220 casos (63%) BETHESDA II; 11 casos (3%) BETHESDA III; 15 casos (4%) BETHESDA IV; 15 casos (4%) BETHESDA V; y 17 casos (5%) BETHESDA VI.

Introduction: Thyroid nodules occur between 4 to 8% of the population, of which up to 15% have neoplastic etiology. Nodules suspected of malignancy require puncture, fine needle aspiration (FNA) and the malignant cytology reported by the Bethesda system must be corroborated with the pathological study once the nodular excision has been performed. The objective of this study is to present the experience of a referral center for patients with thyroid nodules. Methodology: A descriptive, cross-sectional, retrospective study was carried out in the Endocriology Service of the General Hospital of the North of Guayaquil IESS CEIBOS, from June 2017 to July 2019. The Universe was made up of all the cases with a diagnosis of thyroid nodule that required PAAF. It is used in the Bethesda system for reports. Results: There were 349 cases of patients with thyroid nodules, women (89%), aged between 60 - 69 years (26%). 71 cases (21%) BETHESDA I; 220 cases (63%) BETHESDA II; 11 cases (3%) BETHESDA III; 15 cases (4%) BETHESDA IV; 15 cases (4%) BETHESDA V; and 17 cases (5%) BETHESDA VI. Post thyroid nodule malignancy in BETHESDA I 1%; of BETHESDA II 21%; BETHESDA III 56%, BETHESDA IV, 33%; BETHESDA V 71%; and BETHESDA VI 100%. Conclusion: Benign cytology (Bethesda II) was the most predominant, followed by Unsatisfactory Cytology (Bethesda I) with 21%. In the population studied, the real risk of malignancy in thyroid nod-ules that underwent surgery from the Diagnostic Categories cytopathological BETHESDA II, IV, V and VI, confirmed by histopathology; were similar to what was expected, and were within the range esti-mated by the 2017 Bethesda System. The Bethesda III cytopathological category (AUS / FLUS) pre-sented a higher malignancy rate than the upper limit described by the 2017 Bethesda System, con-firming the need for further studies in this type of patient.

RESUMO

PURPOSE: In this study, we aimed to assess the effectiveness of malignancy stratification algorithms of the American College of Radiology (ACR) and European Thyroid Association (ETA) in the delineation of thyroid nodules using a database of nodules that were unequivocally diagnosed by means of histopathological examination and meticulously matched with the imaged nodules. METHODS: A total of 165 patients having 251 thyroid nodules with histopathologically proven definitive diagnoses during a 5-year period were included in this study. All patients had preoperatively undergone ultrasonography (US) examination, and US characteristics of the thyroid nodules were retrospectively analyzed and assigned in compliance with the thyroid imaging reporting and data system categories recommended by the ACR (ACR-TIRADS) and ETA (EU-TIRADS). The diagnostic effectiveness in the delineation of thyroid nodules and unnecessary fine-needle aspiration (FNAB) rates were evaluated. RESULTS: Overall, 189 nodules (75.30%) were diagnosed as benign, while 62 nodules (24.70%) were reported to be malignant based on histopathological assessment. Sensitivity and specificity rates were 71% and 75% for ACR-TIRADS and 73% and 80% for EU-TIRADS. The area under the curve values were 0.78 and 0.80 for ACR-TIRADS and EU-TIRADS, respectively. The unnecessary FNAB rates were 61% for ACR-TIRADS and 64% for EU-TIRADS as per the recommended criteria of each algorithm. CONCLUSION: The diagnostic performance of both malignancy stratification systems was signified to be moderate and sufficient in a cohort of nodules with definite histopathological diagnosis. In light of our results, we demonstrated the strengths and weaknesses of the ACR- and EU-TIRADS for physicians who should be familiar with them for optimal management of thyroid nodules.

RESUMO

BACKGROUND: Fine needle aspiration (FNA) and core needle biopsy (CNB) are two commonly used approaches for the diagnosis of suspected neoplastic parotid gland lesions. We aimed to compare the diagnostic efficiency of FNA and CNB performed with ultrasound guidance preoperatively for the diagnosis of parotid neoplasms. METHODS: We retrospectively analysed the preoperative specimens of 113 patients (66 FNA, 47 CNB) who underwent surgical excision at our institute between 2014 and 2017. Patient selection was based on lesion type and dimension, preliminary and final pathology, imaging characteristics, clinical course, and treatment data for accurate statistical analysis. The final diagnosis was based on surgery in all of the patients. We compared the diagnostic accuracy of FNA and CNB regarding the correct tissue-specific diagnosis of benign and malignant tumours. The recurrence and complication rates were analysed to determine the safety of each technique. RESULTS: Among the 113 patients, the average follow-up period was 65.4 (50-88) months. Seventy-one patients (62.8%) were males, and the median age was 50 years. The most common type of surgery was superficial parotidectomy (83.2%), and the median tumour size was 30.0 mm. Pleomorphic adenoma was the most frequent neoplasm. The diagnostic rates of preoperative pathological evaluation of FNA and CNB samples were 68.2% and 91.5%, respectively. The sensitivity, specificity, and positive predictive value of FNA for detecting malignant lesions were 40, 100, and 100%, respectively, and those of CNB were 100, 100, and 100%, respectively. Only one complication occurred (haematoma) in the biopsy area after CNB. No recurrences were seen after CNB and FNA during the follow-up period. CONCLUSION: Our findings suggest that the diagnostic ability, sensitivity, and specificity of CNB are excellent compared with those of FNA. The only disadvantage of CNB is the need for experienced staff and good-quality equipment. The complication rates of each technique are very low, and the risk of tumour tract seeding is controversial. CNB should be considered the technique of choice when a nodule is detected in the parotid glands.

RESUMO

OBJECTIVES: To determine the role and efficacy of fine needle aspiration cytology (FNAC) and cell block in diagnosis of jaw lesions and compare the agreement between FNAC and cell block to predict the diagnosis. METHOD: The sample comprised 51 cases, including 12 odontogenic keratocysts (OKCs), 8 ameloblastomas, 22 radicular cysts, 7 dentigerous cysts, and 1 each of intraosseous mucoepidermoid carcinoma (MEC) and adenomatoid odontogenic tumor (AOT). FNAC samples remaining after hematoxylin and eosin (H&E)-stained cytosmear diagnosis were centrifuged at 3,000 rpm for 10 min. The supernatant was discarded and sediment mixed with 2-3 mL alcohol and filtered. To this, 10% formalin was added, filtered, taken for routine processing, and stained with H&E. The result of FNAC smear and cell block was compared with histopathological diagnosis. RESULTS: On cytological examination of the smears, 7 OKCs and 22 radicular cysts were diagnosed, whereas ameloblastomas, AOT, intraosseous MEC, and dentigerous cysts were not. This gave an agreement of 56.8% with the biopsy reports. Cell block sections stained with H&E of 12 OKCs, 22 radicular cysts, 1 MEC, and 3 cases of ameloblastoma offered a diagnosis in accordance with the biopsies giving an agreement of 74.5%, while dentigerous cyst and AOT failed to do so. In comparison with FNAC, additionally 5 cases of OKC and 1 of MEC could be detected, and in ameloblastoma, out of 8 cases, only 3 yielded a concordant diagnosis through the cell block technique. CONCLUSION: In comparison with FNAC, the architectural pattern and the morphology of the cells were better preserved by the cell block technique. This substantiates that cell block could be used as an ancillary technique to aid in definitive diagnosis of head and neck swellings.

RESUMO

Objective: To determine the proportion of aspirates reclassified into each Bethesda category and to assess the rates of malignancy in each of them on repeat fine-needle aspiration biopsy (RFNA) following an AUS/FLUS diagnosis. Design: Systematic review and meta-analysis. Methods: On February 2019, Pubmed/MEDLINE, EMBASE, WoS, and the Cochrane Library were searched for articles published from January 1, 2007. All studies published in English describing RFNA outcomes in AUS/FLUS nodules were included. PRISMA and MOOSE guidelines were followed. Five investigators independently assessed the eligibility of the studies. Two investigators extracted summary data and assessed the risk of bias. Data were pooled using a random-effects model. The rate of malignancy was calculated on resected nodules only (upper limit of true value); and considering all unresected nodules were benign (lower limit of true value). The protocol was registered in PROSPERO (CRD42019123114). Results: Of 2937 retrieved studies, 27 were eligible. The meta-analysis was conducted on summary data of 3932 AUS/FLUS thyroid nodules with RFNA. RFNA cytology would reclassify into categories I through VI of Bethesda: 4% (3%, 5%), 48% (43%, 54%), 26% (20%, 32%), 4% (3%, 6%), 5% (3%, 6%), and 2% (1%, 2%) of AUS/FLUS nodules. Malignancy rates of resected nodules were 24% (9%, 38%), 4% (1%, 7%), 40% (28%, 52%), 37% (27%, 47%), 79% (69%, 90%), and 99% (95%, 100%) for categories I through VI of Bethesda. There was high heterogeneity in these data. Conclusions: RFNA reclassified two-thirds of the AUS/FLUS specimens into a more definitive cytological category, with a benign call rate of nearly 50% and a negative predictive value greater than 96%.

RESUMO

Objective:To explore the application value of high frequency ultrasound and ultrasound-guided fine needle aspiration biopsy(US-FNAB) in the diagnosis of papillary thyroid microcarcinoma(PTMC), and to compare the characteristics and value of the two methods, so as to find a more convenient and non-invasive diagnostic method of PTMC, reduce unnecessary puncture and operation. Methods:The data of 190 postoperative pathologically confirmed PTMC patients admitted to Henan Province Cancer Hospital and Henan Provincial Hospital from January to June 2020 were retrospectively analyzed, with a total of 305 nodules, including 198 PTMC nodules and 107 benign thyroid nodules(BTN). According to the postoperative pathological results, they were divided into groups, and the relationship between the ultrasound appearance of the nodules and whether the cervical lymph nodes could be explored and PTMC was analyzed by chi-square test and logistic regression, and its diagnostic value was evaluated. The Kappa consistency test was used to analyze the consistency between ultrasound, FNAB and surgical pathological diagnosis results. The accuracy, sensitivity and specificity of high-frequency ultrasound and US-FNAB were compared, and the ROC curve was used to calculate the maximum area under the curve to evaluate its effectiveness. Results:The chi-square test showed that there were statistically significant differences in the morphology, margin, internal echo, echo uniformity, calcification, aspect ratio, blood flow signal, and whether the cervical lymph nodes can be detected and other ultrasound signs between the PTMC group and the BTN group. Logistic regression analysis showed that irregular shape, unclear edges, internal hypoechoic, intranodular calcification are independent risk factors for PTMC. By consistency test, the consistency between high-frequency ultrasound, US-FNAB examination and surgical pathological diagnosis was good, Kappa value was 0.802 and 0.893(P<0.05). Each nodule was examined by high-frequency ultrasound, and the diagnostic sensitivity, specificity, accuracy and AUC were 95.45%, 83.18%, 91.15% and 0.877 respectively. US-FNAB was performed on 189 of 305 thyroid nodules, and the diagnostic sensitivity, specificity, accuracy and AUC were 96.03%, 93.65%, 95.24% and 0.948 respectively. Conclusion:High frequency ultrasonic features such as internal hypoechoic, calcification in the nodules, unclear edges, and irregular morphology are of high value for the diagnosis of PTMC. Through data analysis, both high-frequency ultrasound and US-FNAB examination have high diagnostic value for PTMC. Compared with US-FNAB, high-frequency ultrasound has the advantages of low examination cost, non-invasive, simple operation and so on. For some patients with PTMC who do not have high risk factors, ultrasound can be used to actively monitor disease progression to avoid some unnecessary surgery.

RESUMO

Introduction: Background The aim of the paper is related to our experience defining the diagnostic accuracy of breast elastosonog-raphy. Objective: The aim of our study is therefore to define the diagnostic accuracy of breast elastosonography in the differential diagnosis of nodular breast neoformations to improve the characterization of the solid lesion and reduce the number of needle aspiration unnecessary for benign formations. Material and methods: A total of 88 patients were enrolled, who came to the Department with an ultrasound diagnosis of a breast lesion. Each lesion was subjected to mammography and B-mode ultrasonogra-phy with an evaluation of size, echogenicity, and vascularization pres-ence or absence. The use of the ultrasound machine and the respective probe has made it possible to make the measurements. All nodules were subjected to ultrasound-guided FNAC. These data were compared with the results of elastosonographic examination. Results: FNAC results were as follows: CIN 1 in 18 nodules, CIN 2 in 22 nodules, CIN 3 in 36 nodules, CIN 4 in 6 nodules, and CIN 5 in 6 nodules. The sensitivity and specificity of elastosonography found in our case series reported values in line with data reported in the literature, confirming the method's high reliability. Conclusions: The elastosonography could become a complemen-tary technique to mammography and ultrasonography in the future, reducing the costs and risks of additional examinations. Therefore, we believe it is essential to contribute with this additional finding to increasingly accredit this pathway and reduce the discomfort to patients of more invasive methods.

RESUMO

AIMS: With ongoing intensive vaccination programme against COVID-19, numerous cases of adverse reactions occur, some of which represent rare events. Enlargement of the injection site’s draining lymph nodes is increasingly reported, but is not yet widely recognised as being possibly associated with recent vaccination. As patients at risk of a severe course of COVID-19, indicated by their medical history such as a previous diagnosis of malignancy, receive priority vaccination, newly palpable lymph nodes raise concerns of disease progression. In this case series, we report on five patients who presented with enlarged lymph nodes after COVID-19 vaccination. METHODS: Sonography guided fine needle aspiration (FNA) was performed in five patients presenting with PET-positive and/or enlarged lymph nodes after COVID-19 vaccination with either the Pfizer-BioNTech or Moderna vaccine. RESULTS: COVID-19 vaccination had been carried out in all cases, with an interval of between 3 and 33 days prior to FNA. Three of five patients had a history of neoplasms. The vaccine was administered into the deltoid muscle, with subsequent enlargement of either the cervical, supra-, infra- or retroclavicular, or axillary lymph nodes, in four out of five cases ipsilaterally. In all cases, cytology and additional analyses showed a reactive lymphadenopathy without any sign of malignancy. CONCLUSIONS: Evidence of newly enlarged lymph nodes after recent COVID-19 vaccination should be considered reactive in the first instance, occurring owing to stimulation of the immune system. A clinical follow-up according to the patient’s risk profile without further diagnostic measures is justified. In the case of preexisting unilateral cancer, vaccination should be given contralaterally whenever possible. Persistently enlarged lymph nodes should be re-evaluated (2 to) 6 weeks after the second dose, with additional diagnostic tests tailored to the clinical context. Fine needle aspiration is a well established, safe, rapid and cost-effective method to investigate an underlying malignancy, especially metastasis. Recording vaccination history, including date of injection, site and vaccine type, as well as communicating this information to treating physicians of different specialties is paramount for properly handling COVID-19 vaccine-associated lymphadenopathy.

RESUMO

RATIONALE: A hormone-active metastatic Hürthle cell thyroid carcinoma (HCTC) and Graves disease (GD) present a therapeutic challenge and is rarely reported. PATIENT CONCERNS: We present a 64-year-old male patient, who had dyspnea and left hip pain lasting 4 months. He had clinical signs of hyperthyroidism and a tumor measuring 9 cm in diameter of the left thyroid lobe, metastatic neck lymph node and metastases in the lungs, mediastinum, and bones. DIAGNOSIS: Laboratory findings confirmed hyperthyroidism and GD. Fine-needle aspiration biopsy and cytological investigation revealed metastases of HCTC in the skull and in the 8th right rib. A CT examination showed a thyroid tumor, metastatic neck lymph node, metastases in the lungs, mediastinum and in the 8th right rib measuring 20 × 5.6 × 4.5 cm, in the left acetabulum measuring 9 × 9 × 3 cm and parietooccipitally in the skull measuring 5 × 4 × 2 cm. Histology after total thyroidectomy and resection of the 8th right rib confirmed metastatic HCTC. INTERVENTIONS: The region of the left hip had been irradiated with concomitant doxorubicin 20 mg once weekly. When hyperthyroidism was controlled with thiamazole, a total thyroidectomy was performed. Persistent T3 hyperthyroidism, most likely caused by TSH-R-stimulated T3 production in large metastasis in the 8th right rib, was eliminated by rib resection. Thereafter, the patient was treated with 3 radioactive iodine-131 (RAI) therapies (cumulative dose of 515 mCi). Unfortunately, the tumor rapidly progressed after treatment with RAI and progressed 10 months after therapy with sorafenib. OUTCOMES: Despite treatment, the disease rapidly progressed and patient died due to distant metastases. He survived for 28 months from diagnosis. LESSONS: Simultaneous hormone-active HCTC and GD is extremely rare and prognosis is dismal. Concomitant external beam radiotherapy and doxorubicin chemotherapy, followed by RAI therapy, prevented the growth of a large metastasis in the left hip in our patient. However, a large metastasis in the 8th right rib presented an unresolved problem. Treatment with rib resection and RAI did not prevent tumor recurrence. External beam radiotherapy and sorafenib treatment failed to prevent tumor growth.
