Breast hematoma with active bleeding due to seat belt injury.

Breast emergencies are not frequent but play an important part in routine breast imaging applications. Diagnosis and identification of seat belt injury in emergency department are essential for patient management and early treatment of advanced cases. Herein we reported imaging findings of a patient who had prominent swollen at her left breast accompanying tissue edema and painful palpable mass formed by active bleeding hematoma as a result of seat belt injury due to a car accident. Radiologic examinations revealed hematoma in the breast accompanying active bleeding.

Machine Learning-Based Ultrasound Texture Analysis in Differentiation of Benign Phyllodes Tumors from Borderline-Malignant Phyllodes Tumors.

PURPOSE: Phyllodes tumors (PTs) are uncommon fibroepithelial breast lesions that are classified as three different forms as benign phyllodes tumor (BPT), borderline phyllodes tumor (BoPT), and malignant phyllodes tumor (MPT). Conventional radiologic methods make only a limited contribution to exact diagnosis, and texture analysis data increase the diagnostic performance. In this study, we aimed to evaluate the contribution of texture analysis of US images (TAUI) of PTs in order to discriminate between BPTs and BoPTs-MPTs. METHODS: The number of patients was 63 (41 BPTs, 12 BoPTs, and 10 MPTs). Patients were divided into two groups (Group 1-BPT, Group 2-BoPT/MPT). TAUI with LIFEx software was performed retrospectively. An independent machine learning approach, MATLAB R2020a (Math- Works, Natick, Massachusetts) was used with the dataset with p < 0.004. Two machine learning approaches were used to build prediction models for differentiating between Group 1 and Group 2. Receiver operating characteristics (ROC) curve analyses were performed to evaluate the diagnostic performance of statistically significant texture data between phyllodes subgroups. RESULTS: In TAUI, 10 statistically significant second order texture values were identified as significant factors capable of differentiating among the two groups (p < 0.05). Both of the models of our dataset make a diagnostic contribution to the discrimination between BopTs-MPTs and BPTs. CONCLUSION: In PTs, US is the main diagnostic method. Adding machine learning-based TAUI to conventional US findings can provide optimal diagnosis, thereby helping to choose the correct surgical method. Consequently, decreased local recurrence rates can be achieved.

Sonoelastography findings of myofibroblastoma.

Myofibrolastoma of the breast (MFB) is a rare and benign stromal tumor. Although MFB is a benign entity, in radiologic evaluation, there is no specific diagnostic feature. Conventional breast imaging findings have been published before. Sonoelastography has been used as an imaging method that allows us to evaluate tissue stiffness in vivo and increases the specificity of B-mode ultrasonography in the discrimination of benign-malignant lesions. In this case report, it was shown that MFB is of high stiffness in shear wave elastography (SWE) evaluation. SWE findings of MFB, which is a benign lesion, have been described for the first time in the literature.

Predictive Factors for Unnecessary Axillary Dissection According to SLN Metastasis in T1, T2 Stage Breast Cancer.

The axillary nodes' status is essential in determining the treatment algorithm according to complete clinical staging. Unnecessary axillary lymph node dissection (ALND) has been prevented after sentinel lymph node biopsy (SLNB) has occurred in current practice. However, approximately half of patients with positive SLNB do not have axillary metastatic lymph nodes. Our study aims to predict unnecessary ALND in patients with SLN metastases by evaluating the patients' clinicopathological data. In total, 221 patients with macrometastasis in SLNB who underwent completion ALND were evaluated retrospectively. Patients were divided into two groups: patients with metastases only in the sentinel lymph node and additional axillary lymph nodes. Univariate and multivariate logistic regression analyses were used to analyze the correlation between SLN metastasis and axillary lymph node metastasis; clinicopathological characteristics, including patient age, menopause status, tumor size and grade, receptor status proliferative marker status, and molecular subtypes of the tumor. In the evaluation of T1-2, cN0 breast cancer patients with SLNB in the form of macrometastasis, only SLNB metastasis was found in 118 (53.4%) patients. In 103 (46.6%) patients, additional axillary node metastasis was observed. The risk of additional nodal spread correlated with patient age older than fertility age (age of 49) (p = 0.015, OR: 1.96, 95% CI: 1.14-3.39) and the number of increased metastatic sentinel nodes (p < 0.001). In line with the data shown by our study, the rate of axillary metastases increases in patients over the age of fertility and as the number of metastatic SLNs increases.

Intra-operative parathyroid hormone evaluation is superior to frozen section analysis in parathyroid surgery.

BACKGROUND: Surgery is currently the only treatment option for patients with primary hyperparathyroidism (PHPT). Recently, minimally invasive parathyroidectomy (MIP) has begun to replace traditional bilateral neck exploration (BNE). OBJECTIVE: The aim of this study is to compare the results of parathyroidectomies performed in our hospital over the past decade that were guided by intra-operative parathyroid hormone (IOPTH) sampling or frozen section (FS) analysis. MATERIAL AND METHODS: Data on 697 patients who underwent parathyroidectomies in the Department of Endocrine Surgery, Dokuz Eylul University between January 2005 and 2018 were included in this study. Patients with malignancies other than thyroid papillary microcarcinoma and parathyroid cancer were excluded from the study. RESULTS: The concomitant use of neck ultrasound (US) and technetium 99m Sestamibi (99mTc MIBI) scintigraphy successfully localized the hyperfunctioning parathyroid glands in nearly 96% of cases. As compared with the IOPTH group, the operation time was longer in the FS group (p < 0.001), and the need for postoperative calcium (Ca) supplementation was higher (p < 0.001). The duration of hospitalization (days) was significantly higher in the FS group (4.2 ± 3.4 vs. 2.6 ± 1.9) as compared with that in the IOPTH group (p < 0.001). In addition, the recurrence rate in the FS group was significantly higher than that in the IPOTH group (p = 0.002). CONCLUSION: IOPTH sampling is a safe and effective method when performed by experienced surgeons and with appropriate preoperative screening. This study emphasizes that IOPTH sampling. We believe that the success in parathyroid surgery is due to three factors: correct indication, accurate localization and experienced surgeon.

Management of the axilla with sentinel lymph node biopsy after neoadjuvant chemotherapy for breast cancer: A single-center study.

The neoadjuvant chemotherapy (NAC) is the gold standard initial treatment of the locally advanced breast cancer (LABC). However, the reliability of methods that used to assess response the NAC is still controversial. In this study, patients with LABC who underwent NAC were evaluated retrospectively. The assessment of response to NAC and the effect of axillary approach were investigated on LABC course.The study comprised 94 patients who received NAC with an LABC diagnosis between 2008 and 2020. In our center, magnetic resonance imaging, ultrasonography, and F-flouro deoxyglucose positron emission tomography/computed tomography, and, for some patients, fine-needle aspiration biopsy of suspicious axillary lymph nodes have been performed to assess the effects of NAC. Patients with positive hormone receptor status received adjuvant hormonotherapy, and those with human epidermal growth factor receptor 2 gene expression were treated with trastuzumab. Adjuvant radiotherapy was applied to all patients undergoing breast conserving surgery. Radiotherapy was applied to the peripheral lymphatic areas in the clinical N1 to N3 cases regardless of the response to NAC.The clinical response to the NAC was found that partial in 59% and complete in 19% of the patients. However, 21.2% of the patients were unresponsive. The mean of lymph nodes that excised with the procedure of sentinel lymph node biopsy (SLNB) was 2.4 (range 1-7). In 22 of the 56 patients who underwent SLNB, axillary dissection (AD) was added to the procedure upon detection of metastasis in frozen section examinations. There was no difference between the SLNB and AD groups regarding overall survival (OS; P = .472) or disease-free survival (DFS) rates (P = .439). However, there were differences in the OS (P < .05) and DFS (P = .05) rates on the basis of the LABC histopathological subtypes.The study found that a relationship between molecular subtypes and LABC survival. However, the post-NAC axillary approach had no effect on OS or DFS. Therefore, multiple imaging and interventional methods are needed for the evaluation of NAC response. In addition, morbidity can be avoided after AD by the use of SLNB in cN0 patients.

Conventional Imaging and Sonoelastography Findings of Oncocytic Breast Carcinoma in a Man.

Oncocytic breast carcinoma (OBC) is one of the rare types of invasive breast carcinoma in according to the classification of The World Health Organization. Herein we represent imaging findings of a case of 69-year-old male patient with OBC.

Hyperthyroidism with thyroid cancer: more common than expected?

OBJECTIVE: Hyperthyroidism is a group of diseases with many different etiologies and clinical manifestations. The most common causes include toxic multi-nodular goiter, Graves' disease and toxic adenoma. The prevalence of thyroid cancer developing in patients with hyperthyroidism has gradually increased in recent years. The aim of this study is to detect the incidental thyroid cancer rates in patients who have undergone a surgical operation due to hyperthyroidism, and to specify the patient groups in whom surgical treatment should come into the foreground. METHODS: A total of 591 patients, who had surgical excision of the thyroid due to hyperthyroidism between January 2007 and June 2017, were retrospectively analyzed. RESULTS: Of all the patients included in the study, 377 (63.7%) had multi-nodular goiter, 132 (22.3%) had Graves' disease, 55 (9.4%) had nodular Graves' disease, and 27 (4.6%) had toxic adenoma. Thyroid cancer was determined in 131 out of 591 patients (22.6%) who were operated. The most common histologic type was thyroid micropapillary carcinoma (65/131; 49.6%). The accompanying pathologies to thyroid cancer were as follows: Toxic multi-nodular goiter (89/131; 67.9%), nodular Graves' disease (24/131; 18.3%), Graves' disease (13/131; 9.9%) and toxic adenoma (5/131; 2.8%). DISCUSSION: Prevalence of cancer on a background of hyperthyroidism has gradually increased in recent years. It is not realistic to determine thyroid cancer prevalence only based on autopsy examinations. This rate significantly increases in the presence of nodule in clinical studies. Most of the carcinomas are microcarcinomas that do not have lymphovascular invasion and have very low lymph node metastasis. Thus, their treatment is still under debate. KEY WORDS: Hyperthyroidism Micropapillary Cancer, Thyroid cancer.

Comparison of Resection and Liver Transplant in Treatment of Hepatocellular Carcinoma.

OBJECTIVES: Hepatic resection and liver transplant are regarded as 2 potentially curative treatments for hepatocellular carcinoma. Here, we compared both options in patients with hepatocellular carcinoma secondary to cirrhosis seen at a single center over 12 years. MATERIALS AND METHODS: We evaluated early complications and survival of patients with hepatocellular carcinoma treated with liver transplant (57 patients) or hepatic resection (36 patients) at our center between 1998 and 2010. RESULTS: The 34-month mean follow-up period was similar for both treatment groups. The liver transplant group had a longer hospital stay than the hepatic resection group (P ⟨ .001). Patients with Child-Turcotte-Pugh A stage were treated by hepatic resection more than by liver transplant (P ⟨ .001),with Child-Turcotte-Pugh B stage patients treated by liver transplant more than by hepatic resection (P = .03). All patients with Child-Turcotte-Pugh C stage had liver transplant. Both treatment groups had similar postoperative complications and early postoperative mortality rates, but liver transplant resulted in longer overall (P = .001) and higher event-free (P = .001) survival than hepatic resection. Among the liver transplant group, 57.8% of patients met the Milan criteria. Patients who met Milan criteria were treated by liver transplant statistically more than hepatic resection, and these patients had longer overall survival (P = .01) and higher event-free survival (P ⟨ .001) than patients who had hepatic resection. Hepatocellular carcinoma recurrence rates were higher after hepatic resection (P = .232). CONCLUSIONS: In patients with hepatocellular carcinoma, hospital stay was longer after liver transplant, but morbidity and mortality rates for liver transplant versus hepatic resection were similar. However, overall and event-free survival rates were better after liver transplant than after hepatic resection. These results suggest that liver transplant should be considered as the primary treatment option for patients with hepatocellular carcinoma secondary to cirrhosis.

Elastography findings of encapsulated solid papillary carcinoma of breast in a man.

Encapsulated solid papillary carcinoma (ESPC) is one of the malignant papillary lesions and classified it as ductal carcinoma in situ. Radiologic features of ESPC have been reported in the literature many times. However, to our best knowledge US elastography findings of ESPC have not been reported in the published literature yet. In this case report, we present US elastography findings of ESPC.

Do the stump knotting technique and specimen retrieval method effect morbidity in laparoscopic appendectomy?

BACKGROUND: Stump closure is the most important part of a laparoscopic appendectomy (LA). Closing the appendix base with knot tying is the most cost-effective method. The defined risk factor for surgical site infection (SSI) after LA is the contamination of trocar entry area by inflamed appendicitis. This study aims to compare the single and double knot technique for stump control and specimen removal methods in LA. METHODS: The data of patients who underwent LA between January 2015 and January 2017 were obtained from prospectively collected database. Single and double knot technique, specimen removal method, operation duration, hospital stay, and perioperative-postoperative complications were compared. RESULTS: Extracorporeal double knot was used in 134 patients (63%), and single knot was used in 79 patients (37%). There was no difference between operation duration in the two groups (p=0.97). No stump leakage was observed in any patient. Intraabdominal abscess developed in three patients (1.4%). Appendix was removed from the abdomen directly in 101 patients (47%) and using specimen retrieval bag in 112 (53%). SSI developed in five patients (2.3%), and appendices of all of these five patients were removed from abdomen without using specimen retrieval bag. No SSI was detected in the group that used the specimen retrieval bag (p=0.02). CONCLUSION: Single or double knot(s) tying can be defined as safe and cost-effective stump closure method. The risk of developing SSI can be reduced using specimen retrieval bag.

Is the extent of surgical resection important in patient outcome in benign and borderline phyllodes tumors of the breast?

Background/aim: Phyllodes tumors (PTs) of the breast are rare, and their diagnosis and treatment remain controversial. This retrospective study aims to examine the clinical outcome of benign and borderline PTs, according to the surgical margins. Materials and methods: We examined the medical records of 122 patients in our clinic, who had histologically confirmed benign and borderline PTs between 1994 and 2017. Results: The mean age of the patients was 40.6 years (range 18.0-81.0, ±12.1 standard deviation [SD]) and the mean tumor size was 25.8 mm (range 9-65, ±10.3 SD). All patients underwent a breast-conserving procedure and the median follow-up was 51 months. Tumor margins were positive (tumor touching the ink) in 43 patients (35%). Only 16 patients (13%) had margins ≥10 mm. The margins were between 2 and 10 mm in most patients (40%) and ≤1 mm in 12% of the patients. Conclusion: Although no re-excision was performed to obtain grossly clear margins, local recurrence was not observed in any patients. Therefore, revision surgery for close or positive surgical margins for benign and borderline PTs should not be performed as a rule. As most tumors recur within 2 years of diagnosis, we propose a close clinical and imaging follow-up during this period.

The effectiveness of simultaneous oncoplastic breast surgery in patients with locally advanced breast cancer.

BACKGROUND: Oncological outcomes of the oncoplastic breast surgery in patients with locally advanced breast cancer (LABC) are not well defined. This study examined the effects of oncoplastic techniques for LABC in terms of localized control and survival. We also evaluated the esthetic results of patients who had undergone oncoplastic breast conservation surgery (OBCS) and their satisfaction with the outcome. METHODS: The files and Medula (Probel Co.) database records of the patients were studied retrospectively. The esthetic evaluation was conducted by a panel. A validated satisfaction study was also performed. RESULTS: In total, 42 LABC cases (median age 48 years; range 33-69 years) were included. The median observation period was 61 months (range 26-151 months). Neoadjuvant chemotherapy (NACT) was administered in 32 (76%) cases, and a pathologic complete response was observed in 7 (16.7%) cases. The median T size during the post-NACT pathological study was 27 mm (range 0-44 mm). Oncoplastic reduction surgery was performed in 13 cases, a glandular flap in 7, Grisotti flap in 5, and latissimus dorsi flap in 3 cases. The median specimen weight was 198 g (range 103-812 g), and the mean surgical margin length was 8.7 mm (range 5-17 mm). The margin was positive in 7.1% of cases, and the local repetition rate was 14.6%. The total survival rate was 86.6%, and disease-free survival was 59.6%. The rate of excellent and good ratings by the esthetic assessment panel was 79.4%. The satisfaction rate was 88.2%. The early and delayed complication rate was 16.7%. CONCLUSIONS: Oncoplastic techniques are suitable and safe for patients undergoing OBCS. These techniques do not pose a risk to oncological local control. No survival or follow-up problems were detected during the 5-year follow-up period, the esthetic results were acceptable, and the satisfaction rate was high.

Five years with a rectal foreign body: A case report.

INTRODUCTION: Rectal foreign bodies are rare colorectal emergencies. They are important for the complications that may occur. Delayed response causes a wide range of complications or may even result in death. PRESENTATION OF CASE: A 22 years old male patient was seen at our hospital with anal pain, discharge, and complaining of incontinence. The patient stated that a bottle of beverage was placed into his anal canal in an inverted manner for sexual satisfaction 5 years previously. DISCUSSION: After clinical and radiological assessment under general anaesthesia in the lithotomy position the object was removed by a laparotomy. He was advised to seek legal help and he received psychiatric treatment in the postoperative period prior to his discharge. CONCLUSION: Complications such as abscess, perianal fistula complicated by severe pelvic sepsis and osteomyelitis were expected complications in this case. As in this case, a surgical approach may eliminate dissection planes, increasing morbidity and mortality related to the injuring of surrounding bodies during object extraction.
