Conduction System Hamartoma: Autopsy Case Series.

Conduction system hamartoma is a benign hamartomatous lesion arising from Purkinje and Purkinje-like cells of the heart. We aimed to investigate the cases that we detected during postmortem histopathological examination. The histopathology reports of the cases autopsied between 2012 and 2022 were reviewed retrospectively.

The Epidermal Growth Factor, Anaplastic Lymphoma Kinase, and ROS Proto-oncogene 1 Mutation Profile of Non-Small Cell Lung Carcinomas in the Turkish Population: A Single-Center Analysis.

The management of non-small cell lung carcinomas (NSCLC) has changed with the identification of molecular pathways. We aimed to reveal the 3-year epidermal growth factor (EGFR), anaplastic lymphoma kinase (ALK), and ROS proto-oncogene 1 (ROS1) mutation profile in the Turkish population. The histopathological and molecular data of all NSCLC cases from our department between May 2019 and April 2022 were evaluated.

Is That Innocent to Touch the Adipose Tissue?: An Autopsy Case Series of Fat Embolism Syndrome.

Although fat embolism in the pulmonary or systemic circulation is usually associated with long bone fractures, it can also occur less frequently during surgical operations, such as liposuction, fat grafting, and joint repair. This study aims to present cases of macro fat embolism resulting in sudden death during the perioperative period. Three cases with a history of sudden death during the perioperative period were included in this study.

Eosinophilic myocarditis from a forensic histopathological perspective.

Eosinophilic myocarditis (EM) is a rare and potentially fatal form of myocarditis characterized by infiltration of the myocardium with eosinophil leukocytes, often accompanied by eosinophilia. Although the exact underlying cause remains unknown, it has been shown to be associated with hypersensitivity reactions, immune-mediated disorders, infections, or cancer. Due to the differences in symptomatology, it is often diagnosed by postmortem histopathological examination.

Coexistence of low-grade mucinous neoplasm and carcinoid (collision tumor) within multiple appendiceal diverticula: A case report.

Neoplasms of the appendix are very rare. They usually show glandular or neuroendocrine differentiation, and when they both occur in the same area, it is called a "collision tumor." Low-grade mucinous neoplasms associated with appendiceal diverticula are also uncommon.

Cribriform glands are associated with worse outcome than other pattern 4 subtypes: A study of prognostic and clinicopathological characteristics of prostate adenocarcinoma with an emphasis on Grade Groups.

Aim: Although prostate adenocarcinoma is the most common cancer in men, survival is quite high and with the help of histopathological examination using the updated classification, patient management strategies are developing. We aimed to evaluate the correlation between the histopathological features and biochemical recurrence (BCR) in patients who underwent radical prostatectomy (RP) using the new classification.

Methods: A total of 285 prostate adenocarcinoma cases that underwent RP between January 2009 and December 2017 and followed up for at least 3 months were included in the study.

Giant IgG4-Related Pseudotumor of the Esophagus Resected with Endoscopic Submucosal Dissection: A Case Report and Review of the Literature.

IgG4-related disease (IgG4-RD) is a systemic autoimmune disorder that has been defined in various organs. The disease is characterized by typical clinicopathological features including a dense lymphoplasmacytic infiltrate rich in IgG4 positive plasma cells, storiform fibrosis, obliterative phlebitis, and often an elevated serum IgG4 level. Esophageal IgG4-RD is rare, and its presentation as a solid mass is even more rare.

Epithelioid trophoblastic tumor in a postmenopausal woman: A case report and review of the literature in the postmenopausal group.

Epithelioid trophoblastic tumor is a rare gestational trophoblastic neoplasm arising from the intermediate trophoblasts. Although usually seen in the reproductive period, it may be encountered during the postmenopausal period. A 56-year-old woman who had given her last birth 21 years ago presented to the hospital with a complaint of postmenopausal bleeding.

Endoscopic Submucosal Dissection of Seborrheic Keratosis-Like Lesion of the Esophagus: A New Entity?

Seborrheic keratosis, one of the most common lesions of the epidermis, is rarely seen on mucosal surfaces. We report a case of a distinctive epithelial neoplasm of the esophagus showing close resemblance to seborrheic keratosis that was resected with endoscopic submucosal dissection. A 65-year-old patient's previous esophageal biopsy showed suspicious low grade dysplasia and the patient was referred for endoscopic submucosal dissection of a flat lesion in the mid-esophagus.

Coexistence of low-grade mucinous neoplasm and carcinoid (collision tumor) within multiple appendiceal diverticula: A case report.

Neoplasms of the appendix are very rare. They usually show glandular or neuroendocrine differentiation, and when they both occur in the same area, it is called a "collision tumor." Low-grade mucinous neoplasms associated with appendiceal diverticula are also uncommon.

Unusual locations of hydatid disease: A 10-year experience from a tertiary reference center in Western Turkey.

Introduction: Hydatid disease is an endemic parasitic infection caused by Echinococcus granulosus mostly seen in the Mediterranean countries. The most affected organ is the liver, however hydatidosis can be found anywhere in the human body.

Methods: The records of patients who were diagnosed with hydatid disease in our hospital from December 2005 to February 2016 were analyzed retrospectively.
