RESUMEN

We report here a case of disseminated Emergomyces pasteurianus infection from India in a patient with AIDS. The patient presented with weight loss, dyspnoea and multiple non-tender skin lesions over face, neck and chest over 3 months. The case was diagnosed by microscopy, histopathology of sample and isolation of fungus from skin lesion, breast nodule, bone marrow and sputum. The identification of the isolates was confirmed by sequencing internal transcribed spacer region of rDNA, beta-tubulin, actin and intein PRP8. The patient responded well to intravenous amphotericin B deoxycholate followed by itraconazole therapy.

RESUMEN

We present a rare case of a 30-year-old woman who presented with a swelling on the lateral aspect of her left forearm, present since 6 months, adjacent to a 16-year-old burn scar. X-ray of elbow joint and forearm revealed the subcutaneous nature of the swelling. Giemsa and periodic acid-Schiff-stained smears and potassium hydroxide mount of fine-needle aspirate of the swelling revealed dematiaceous, branching, and septate fungal hyphae. Fungal culture of the aspirated pus showed growth of Exophiala jeanselmei. Histopathological examination revealed brown-coloured hyphae with foreign body giant cell reaction and palisading granulomas in the surrounding tissue. The patient was successfully treated with surgical excision of the swelling. All the cases of phaeohyphomycosis due to Exophiala spp. in India are also reviewed.

RESUMEN

The diagnosis of atypia has always been under question both by the pathologist and the clinician. It was one of the main aims of the Paris system (TPS) to reduce the number of cases under the AUC (Atypical urothelial cells) category. With the strict criteria laid down by the Paris system, the rate of diagnosis of this category has reduced markedly. This study was done to test the impact of implementing TPS categories and criteria in comparison to our previously used system. TPS is one of the important deciding factors for the management of the patient. The management of patients with AUC diagnosis often varies depending on the treating physician (urologist/nonurologist). For further categorization of the diagnosis of AUC, markers like p53 and Ki67 can be used. One hundred urinary cytology specimens received for the period of 6 months were included in the study. The presentation of the categorical variables was done in the form of numbers and percentages (%). Interrater kappa agreement was used to find out the strength of the agreement between the Paris system and the traditional system. Using histopathological diagnosis as the gold standard, sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic accuracy were calculated. Immunohistochemistry was performed on the cell block for Ki67 and p53, and their values were correlated with histopathological examination, using Spearman's rank correlation. The interrater kappa agreement analyzed between the traditional reporting system and the Paris system was 0.522. Around 32% (6/19) of cases that were reported as AUC by the traditional system were recategorized under negative for high-grade urothelial carcinoma (NHGUC) by the Paris system. Thus, obliviating the need for further management and decreasing the unnecessary cost of the health care system with a decrease in patient anxiety. Histopathology was available in 28 cases and diagnostic accuracy of urine cytology classified by TPS was 89.2% with a sensitivity of 94.4%, specificity of 80%, positive likelihood ratio of 89.4, and negative likelihood ratio of 88.6. The correlation coefficient of p53 with grading of carcinoma was found to be strong at 0.864. The correlation coefficient of Ki67 with grading of carcinoma was also as strong as 0.885. TPS along with immunohistochemistry improves the performance of urine cytology by reclassifying the AUC category into other groups and increases the sensitivity for detecting HGUC.

RESUMEN

In low-resource settings, a point-of-care test for cervical cancer screening that can give an immediate result to guide management is urgently needed. A transvaginal digital device, "Smart Scope®" (SS), with an artificial intelligence-enabled auto-image-assessment (SS-AI) feature, was developed. In a single-arm observational study, eligible consenting women underwent a Smart Scope®-aided VIA-VILI test. Images of the cervix were captured using SS and categorized by SS-AI in four groups (green, amber, high-risk amber (HRA), red) based on risk assessment. Green and amber were classified as SS-AI negative while HRA and red were classified as SS-AI positive. The SS-AI-positive women were advised colposcopy and guided biopsy. The cervix images of SS-AI-negative cases were evaluated by an expert colposcopist (SS-M); those suspected of being positive were also recommended colposcopy and guided biopsy. Histopathology was considered a gold standard. Data on 877 SS-AI, 485 colposcopy, and 213 histopathology were available for analysis. The SS-AI showed high sensitivity (90.3%), specificity (75.3%), accuracy (84.04%), and correlation coefficient (0.670, p = 0.0) in comparison with histology at the CINI+ cutoff. In conclusion, the AI-enabled Smart Scope® test is a good alternative to the existing screening tests as it gives a real-time accurate assessment of cervical health and an opportunity for immediate triaging with visual evidence.

RESUMEN

Objectives: Cytological examination of effusion sample is a preliminary and minimally invasive method for the diagnosis of body fluids. Recently, the International System For Reporting Serous Fluid Cytopathology (ISRSFC) and the Indian Academy of Cytologist (IAC) have published guidelines for reporting effusion cytology and calculating the risks of malignancy (ROMs) for each defined category. We report our 2 years of experience in reclassifying and assessing the feasibility of applying ISRFSC and IAC categories to effusion fluid and to provide an estimate of the risk of malignancy for each diagnostic category. Material and Methods: Cytological reports of patients from January 2019 to December 2020 were retrieved and reclassified into a five-tiered classification scheme as per ISRSFC guidelines. Cellblock and immunohistochemistry were performed in selected cases. Clinico radiological and histopathological information were obtained and correlated with the cytological findings wherever available. Results: In the study, 652 cases were included during the 2 years. Out of these, 328 (50.3%) were women and 314 (47.3%) were men. Patient's ages ranged between 2 92 years with a mean age of 47.4 years. There were 366 (56.1%) cases of ascitic fluid followed by 262 (40.1%) cases of pleural fluid and 24 (3.8%) cases of pericardial fluid in the analysis. Of all the cases, 13 (2%) were non-diagnostic (ND), 464 (71.6%) were negative for malignant (NFM) cells, 16 (2.4%) were atypia of uncertain significance, 31 (4.7%) were suspicious of malignancy, and 125 (19.3%) were malignant. Cellblock was prepared in 65 cases. Lung cancer followed by breast cancer was the most common malignancies involving the pleural effusion and ovarian cancer was the most common cause of peritoneal effusion. ROM for each diagnostic category was 23% for ND, 25% for NFM, 56% for the atypical category, 80.6% in suspicious, and 90% were for positive for malignancy category. Conclusion: The use of a five-tiered system as per the ISRFC and IAC guidelines are feasible for the standardized reporting of effusion samples, thus avoiding subjective variation of reporting.

RESUMEN

Lichen scrofulosorum is the most common tuberculid in the Indian population and the second most common form of cutaneous tuberculosis. We discuss an uncommon presentation of lichen scrofulosorum, with psoriasiform morphology and koebnerization at tuberculin test site, associated with cervical lymphadenitis in a 17-year-old girl. Although the cutaneous lesions resolved completely after 3 months of antitubercular treatment (ATT), she developed scrofuloderma in the left cervical region at 4 months. In the absence of rifampicin resistance, ATT was continued for another 6 months, with no further evidence of disease activity. This case represents an infrequent occurrence of lichen scrofulosorum followed by scrofuloderma, which necessitated a prolonged course of first-line ATT.

RESUMEN

OBJECTIVE: Sternocleidomastoid tumor of infancy (SCMI) is a rare, benign self-limiting condition which occurs in the perinatal period. The goal of our study is to highlight clinicoradiological and cytopathological findings in these cases. MATERIAL AND METHODS: A study was done at a tertiary level hospital, from January 2016 to December 2019. Thirteen cases were studied, out of which 11 were clinically suspected cases of SCMI tumor and two cases were clinically suspected as cervical lymph node tuberculosis which were finally diagnosed as SCMI on fine needle aspiration cytology (FNAC) evaluation. Drs. N. K., S. Z., S. S. K., and S. R. independently reviewed the original diagnosis. Clinical, ultrasonographical, and cytopathological features are highlighted along with follow-up of the cases. RESULTS: There were a total of 13 cases, out of which 11 cases were neonates and two cases were more than 1 month of age (2 months and 2.5 months). Male: female ratio was 10:3 and swelling was present more commonly on the right side of the neck. Ultrasonography predominantly showed non-cystic, bulky, and heterogenous echotexture of the sternocleidomastoid muscle. Smears were moderately cellular showing mainly singly scattered oval to spindle shaped fibroblasts along with degenerating and regenerating muscle fibers. CONCLUSION: FNAC along with adequate clinic-radiological correlation aids in early and reliable diagnosis and can help curtail complications.

RESUMEN

Filariasis is a vector-borne disease, which is quite common in tropical countries such as India. In India, it is most commonly caused either by Wuchereria bancrofti or Brugia malayi. It can present in any possible site, possibly, because of their ability to migrate along the lymphatics. Very few cases have been reported in the literature where microfilariae have been found in cervicovaginal smears. Most of the cases have been reported on conventional Pap smears. Here, we present two such cases where microfilaria was found as an incidental finding in liquid-based cytology preparation.

RESUMEN

INTRODUCTION: Frozen section is a well-established method for providing rapid and accurate intraoperative diagnosis. Cytological techniques such as imprint and scrape cytology and intraoperative fine-needle aspiration cytology are conventionally considered as less accurate alternatives to the frozen section. However, inexperienced hands, scrape cytology has been shown to provide remarkably accurate results comparable to the frozen section. AIMS: The aims of this study are as follows: (1) To evaluate the diagnostic utility of scrape cytology in the intraoperative diagnosis of ovarian neoplasms. (2) To compare the accuracy of scrape cytology with frozen section in the intraoperative diagnosis of ovarian neoplasms. MATERIALS AND METHODS: This study was conducted over a period of 3 years from 2014 to 2017. A total of 60 cases of clinically and radiologically suspected ovarian masses were included in the study. Thirty cases were evaluated using frozen section and 30 cases using scrape cytology alone. The intraoperative diagnosis of both was compared with the final paraffin section histopathology. RESULTS: The diagnostic accuracy of scrape cytology and frozen section in determining a benign and malignant nature of neoplasm was 96% and 100%, respectively. In 93% of cases, scrape cytology enabled correct categorization of the tumor as surface epithelial, germ-cell tumor, sex cord-stromal, or others. CONCLUSION: Scrape cytology is an adjunct to frozen section for providing an intraoperative diagnosis; however, in resource-poor settings, it can be used as a stand-alone method for aiding intraoperative decision-making.

RESUMEN

Transitional cell carcinoma (TCC) arising from renal pelvis rarely gives rise to cutaneous metastasis. Due to the insufficient literature, the exact incidence is not known till date. Moreover, the diagnosis is confirmed on histopathological examination with the aid of immunohistochemistry wherever needed. We are presenting a case of a 70-year-old female with metastatic TCC from the renal pelvis to the abdominal skin, which was diagnosed on cytology alone along with the cell block preparation. We also highlight the important cytomorphological and immunohistochemical features noted, which need to be known to avoid any diagnostic delay.

RESUMEN

Carcinosarcoma of the parotid gland, a true malignant mixed tumour is extremely rare. It may occur in a pre-existing pleomorphic adenoma or arise de novo. We report a case of carcinosarcoma de novo harbouring an osteosarcomatous element in a 35-year-old man along with review of the reported cases. Excision was done and histopathologic examination confirmed the diagnosis. Long term follow up has been recommended for these tumours owing to their high propensity of recurrence and metastasis. Our case discusses the importance of histopathology and limitation of preoperative imaging in the diagnosis of such an aggressive neoplasm; emphasizing the fact that possibility of carcinosarcoma should be kept in mind while dealing with salivary gland lesions even at a younger age.

RESUMEN

BACKGROUND: Polycystic ovary syndrome (PCOS) is a metabolic syndrome, characterized by anovulation, hyperandrogenism, and polycystic ovary. With serological markers of autoimmunity found elevated in PCOS, there is a possible link between autoimmunity and PCOS. AIM: The study aimed to investigate the possible correlation between autoimmune markers of autoimmune thyroiditis (AIT) and PCOS. SETTING AND DESIGN: This case control study was conducted at the Department of Pathology of a tertiary care academic center during a 1-year period. MATERIALS AND METHODS: Fifty-five subjects with clinical PCOS and 51 age matched control non-PCOS subjects were recruited and subjected to clinical, biochemical, and endocrinal evaluation for AIT. All subjects underwent blood glucose and serum sampling for luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone, dehydroepi androsterone, thyroxine, thyroid stimulating hormone, anti-thyroid peroxidase, anti-thyroglobulin (Tg), and insulin. STATISTICAL ANALYSIS: Statistical analysis was performed using SPSS version 12 for Windows. The quantitative variables are described as mean ± standard deviation. To compare quantitative variables between two groups, unpaired t-test was used. The Chi-square/Fischer's exact test was used to compare qualitative variables. ANOVA was used to compare the PCOS and non-PCOS groups. P < 0.05 was considered significant. RESULTS: Significantly higher prevalence of AIT (anti-Tg antibodies) was noted in subjects with PCOS as compared to non-PCOS control subjects (P < 0.05). The PCOS subjects had higher insulin resistance index and also twice the level of LH: FSH ratio as compared to controls. CONCLUSION: Higher prevalence of AIT in PCOS subjects suggest possible role of autoimmune phenomenon in the etiopathogenesis of PCOS. More data from longitudinal follow-up studies is required to clearly establish this possible link.

RESUMEN

The most common causes of renal mass with malignant venous thrombosis are Wilms' tumor and renal cell carcinoma. Although renal involvement may occur in disseminated lymphomas, primary renal Burkitt lymphoma (BL) is rare. Vascular tropism is not a usual feature of lymphoma; thus, primary renal BL with venous extension is distinctly unusual. However, it is important to diagnose this entity because such patients respond well to medical management and may not require surgery. We report a pediatric case of primary renal BL with malignant vascular thrombus and systemic dissemination where biopsy was diagnostic and enabled appropriate treatment.

RESUMEN

Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy is a rare disease involving the lymph nodes. Extranodal RDD involving the thyroid is extremely rare. So far, six cases of RDD involving thyroid have been reported in the literature; all have occurred in females with a mean age of 56.3 years. Clinically, radiologically and cytologically, all the cases were initially diagnosed as thyroid malignancies with lymph nodal metastasis. The final diagnosis was made histologically only after total thyroidectomy. We herein, present a seventh case of RDD involving the thyroid in a 15-year-old female, diagnosed first on fine needle aspiration cytology (FNAC). We conclude that FNAC is a useful diagnostic procedure for RDD involving thyroid; it can avoid an unnecessary thyroidectomy.
