Routine careful histopathological examination should be performed in sleeve gastrectomy specimens

Introduction: The presence of increased ratio of obesity caused a rapid increase of bariatric surgery practice. In this study, our purpose is to clarify the histopathologic findings of the patients who have experienced this type of bariatric surgery and to learn more about the distinguishable features of laparoscopic sleeve gastrectomy (LSG) specimens and to contribute to the related literature. Methods: A retrospective study was designed with the histopathologic findings from pathology specimens of 109 patients who experienced LSG between April 2014 and May 2016. To collect essential data, we used the database system of our institution that contains all of the selected patients for our study. Results: Overall, the average age was 36.2 years, and 85 were female while 24 were male. The principal histopathologic features were active chronic gastritis in 9, chronic gastritis in 68, atrophy in 5, and intestinal metaplasia in 8 patients. In two patients, gastrointestinal stromal tumor was found and in another patient, neuroendocrine cell hyperplasia was found. In addition to the dominant histopathologic features including chronic and active chronic gastritis, a small percent of patients had clinically significant pathologic findings in the sleeve gastrectomy specimens and this may have an effect on postoperative management and morbidity. Conclusion: Considering these results, having histopathologic examination of the sleeve gastrectomy specimens as a standard procedure is strongly recommended

Cutaneous syncytial myoepithelioma: A potential pitfall in the differential diagnosis of superfi cial dermal tumors

In the spectrum of myoepithelial tumors of the skin, cutaneous myoepithelioma is composed solely of myoepithelial cells. Cutaneous syncytial myoepithelioma as a rare histological variant of cutaneous myoepithelioma has been fi rst described in the last decade. This tumor is benign and rarely shows recurrence when incompletely resected. In addition to its distinctive common histological and immunohistochemical features, cutaneous syncytial myoepithelioma shares the same changes for most cases in molecular testing (EWS RNA binding protein 1 gene rearrangement). The differential diagnosis of other superfi cial dermal tumors is one of the major diffi culties in the diagnosis of this tumor. In the current study, we present our fi ndings of a 56 year-old woman who was diagnosed as cutaneous syncytial myoepithelioma.</p

Development of Two Types of Skin Cancer in a Patient with Systemic Sclerosis: a Case Report and Overview of the Literature

Systemic sclerosis (SSc) is an uncommon rheumatic disease in which the underlying main histopathologic feature is a thickening of the skin due to excessive accumulation of collagen in the extracellular tissue. Fibrogenesis, chronic inflammation, and ulceration may eventually promote skin neoplasms. Although nonmelanoma skin cancer (NMSC) is the most frequent type, there have been restricted case reports and case series with skin cancers in SSc patients in the literature. Herein, we describe a 78-year-old woman diagnosed with diffuse cutaneous systemic sclerosis thirteen years ago and associated nonspecific interstitial pneumonia that was successfully treated with high cumulative doses of cyclophosphamide. She developed basal cell carcinoma and squamous cell carcinoma of the skin in the follow-up. She is still on rituximab treatment with stable interstitial lung disease as indicated by pulmonary function tests and high-resolution chest computed tomography. To our knowledge and a literature search, this is the first reported patient with SSc with two types of skin cancer. In this review, we also aimed to emphasize the relationship between SSc and skin cancer, and possible risk factors for SSc-related skin cancer

The value of multimodal ultrasonography in the evaluation of late presenting testicular torsion in a rat experimental model

Objective To evaluate the value of multimodal ultrasonography (US) in a rat experimental torsion model after 6 h of torsion with different degrees. Methods Twenty-one male rats were divided into three groups. Left testes of the rats were twisted around their vascular pedicle 360 degrees in group 1, 720 degrees in group 2, and 1080 degrees in group 3 and intact right testes of the rats were accepted as control group. Grey-scale US, superb microvascular imaging (SMI), colour Doppler ultrasonography (CDUS), strain elastography (SE), and two-dimensional (2-D) shear wave elastography (SWE) examinations were applied 6 h after torsion procedure and testes were removed for pathological evaluation. Results Short-axis dimensions and volumes of the torsion side were higher than control testes. Lengths of the testes in the 3rd torsion group were smaller than the testes in groups 1 and 2 (P 0.002). SMI was better than CDUS in recognizing blood flow in testicular tissue. Strain ratios were higher in group 1 and decreased with the increasing torsion degree. Emean and standard deviation (SD) measurements increased in the torsion side. Pathologically the mean testicular damage scores were statistically significant between torsion and control testes in all groups. Conclusion Our results showed that short-axis and volume measurements, SMI, 2D-SWE, and SE are effective in the evaluation and diagnosis of testicular torsion (TT). Advances in knowledge Evaluation of affected testis and intact testis with multiparametric US in late presenting TT cases is more reliable than being dependent on a single sonographic modality

Properties of synchronous versus metachronous bilateral breast carcinoma with long time follow up

Background: Breast cancer is the most common cancer type among women with increasing incidence rates, improved prognosis and survival. According to the localization of the tumor, breast cancer is designated as unilateral (UBC) or bilateral (BBC). BBC can be classified as synchronous (SBBC) or metachronous (MBBC) based on the time interval between the diagnosis of the first and the secondary tumors. According to the guideline of WHO 2012, BBC is generally defined as SBBC when contralateral breast carcinoma is diagnosed within 3 months. The aim of this study was to compare the characteristics and patterns of metastasis of BBC patients with UBC. Materials and Methods: A cohort of 768 patients with breast cancer treated at the Turkish Ministry of Health-Izmir Bozyaka Research and Training Hospital between 1976 and 2012 were studied. Survival analysis was performed comparing UBC and BBC patients. In addition, evaluations were performed in patients with SBBC and MBBC sub-groups. We used a 3-months interval to distinguish metachronous from synchronous. Results: When clinical and histopathological parameters were statistically evaluated, ER status, event-free and overall survival were found to be significant between UBC and BBC patients. In comparison of SBBC and MBBC patients, age, histological type of tumor, event-free and overall survival were found to be significant. Conclusions: BBC cases were found to show worse prognosis than UBC cases. Among BBC, SBBC had the worst prognosis based on overall survival rates

Claudin 18.2 expression in esophageal adenocarcinoma and its potential impact on future treatment strategies

The incidence of esophageal adenocarcinoma (EAC) has rapidly increased, particularly in the Western world. Despite improvements in perioperative treatments, the overall survival of patients remains low. Claudin 18.2 is a tight junction protein that is exclusively expressed in the gastric epithelia. However, following malignant transformation, gastric cancer metastases maintain this expression. Therefore, claudin 18.2 is a promising target for immunotherapy. Previous clinical trials have revealed improved anti-tumor activity in patients treated with an anti-claudin antibody by investigating the expression of claudin 18.2 in tumor cells. However, there is currently very limited data on the importance of claudin 18.2 expression in EAC. The present study analyzed the distribution of claudin 18.2 using immunohistochemistry in 485 patients with EAC, including their lymph node metastases. Additionally, these results were associated with clinical and molecular data. Claudin 18.2 was detected in 89/485 patients (18.4%). No correlations between expression and clinicopathological data (sex, age, pT stage, lymph node metastasis and grading) were observed. However, significantly decreased claudin 18.2 expression was observed in tumor types with upregulated human epidermal growth factor receptor 2 expression (P=0.036). Additionally, neoadjuvant treatment did not have any significant impact on claudin 18.2 expression (P=0.331). To the best of our knowledge, the present study is the largest systematic investigation of claudin 18.2 protein expression in EAC. The results obtained suggested that claudin 18.2 may serve as a promising therapeutic target in a substantial number of patients with EAC

Reliability, diagnostic value, and diagnostic yield of ultrasound-guided percutaneous core needle biopsy for peritoneal lesions

IntroductionPeritoneal lesions cannot be definitively distinguished based on clinical and imaging characteristics alone. This study aimed to evaluate the reliability, diagnostic value, and diagnostic yield of ultrasound-guided percutaneous core needle biopsy (PCNB) for peritoneal lesions.MethodsA retrospective analysis of 129 patients who underwent PCNB for peritoneal lesions was performed to assessed technical completion and diagnostic yield.ResultsThe results showed that ultrasound-guided PCNB is a safe and reliable diagnostic tool with high diagnostic yield for peritoneal lesions. Technical feasibility and diagnostic yield rates were 100% and 89.9%, respectively. The diagnostic yield was lower for patients with a known history of cancer and a short anteroposterior diameter of the target lesion.ConclusionsThese findings suggest that ultrasound-guided PCNB could be considered as a first-line diagnostic tool for peritoneal lesions, as it offers a minimally invasive and accurate means of obtaining tissue samples for diagnosis. Percutaneous ultrasound-guided needle core biopsy is a safe and reliable diagnostic tool with high diagnostic yield for peritoneal lesions. History of cancer and the anteroposterior diameter of the target lesion affect the diagnostic yield of percutaneous biopsy.imageWe would like to thank Wiley Editing Services () for English language editing
