Objective: Our aim in this study is to define the histopathological subtypes, body site distribution, and incidence rates of single or multiple of BCCs. The study is conducted on patients from a single institution in Istanbul which has a migrant-receiving population reflecting that of the country overall.
Method: We retrospectively analyzed data concerning 896 cases of BCC seen between 2014 and 2018.
Background/aim: Cutaneous adnexal tumors (CAT) are rare tumors originating from the adnexal epithelial parts of the skin. Due to its clinical and histopathological characteristics comparable with other diseases, clinicians and pathologists experience difficulties in its diagnosis.We aimed to reveal the clinical and histopathological characteristics of the retrospectively screened cases and to compare the prediagnoses and histopathological diagnoses of clinicians.

Humans acquire Toxocara infection by accidental consumption of eggs contaminated foods, soil, water or larvae encapsulated in the viscera or meats of various paratenic hosts e.

Nowadays, pathologists are required to perform immunohistochemistry to demonstrate neuroendocrine and epithelial differentiation for diagnosis of MCC. Insulinoma-associated protein 1 (INSM1) is a zinc-finger transcription factor expressed in tissues undergoing terminal neuroendocrine differentiation, and INSM1 immunohistochemistry is a well-validated nuclear marker of neuroendocrine differentiation.

Methods: Overall, 30 non-diabetic patients and 30 type II diabetic patients who underwent lumbar microdiscectomy were included in this study. All patients underwent lumbar microdiscectomy, and IVD samples were obtained during the surgery.

Introduction: The pathological diagnosis of papillary thyroid carcinoma (PTC) is generally easy on routine sections stained with hematoxylin and eosin (H&E). However, the differentiation of the follicular variant of PTC (FVPTC) from other suspected follicular-patterned lesions of the thyroid is highly difficult. Among these, the lesions for which FVPTC cannot be excluded are classified as well-differentiated tumors of uncertain malignant potential (WDT-UMP).

When a NET is found in the liver, it must be treated to exclude metastasis from extrahepatic primary sites. The patient was a 38-year-old female.

Methods: Samples obtained from the skin of the external ear canal (EEC) of patients operated for chronic otitis media (COM) without cholesteatoma constituted Group 1; samples from the EEC skin of patients in Group 3 operated for COM with cholesteatoma and from the EEC skin of patients in Group 4 constituted Group 2; samples obtained from the cholesteatoma matrix of patients operated for COM with primary acquired cholesteatoma constituted Group 3; and samples obtained from the cholesteatoma matrix of patients operated for COM with secondary acquired cholesteatoma constituted Group 4. The assessment of the positive cell ratio was based on the presence of the following findings and was semiquantitatively classified into four groups: 0, no staining; + cell staining (weak positive staining: 1%-33%); ++ cell staining (moderately positive staining: 34%-66%); and +++ cell staining (strong positive staining: 67%-100%).
Objective: To examine the expression of Mullerian inhibiting substance (MIS) in papillary thyroid cancer.
Materials And Methods: The MIS expression was examined by studying the immunohistochemistry in deparafinized sections prepared from tissue blocks of patients who were diagnosed with papillary thyroid cancer, as given in the pathology archive records (n = 23).
Results: In all the cases studied, 50% (n = 10) showed strong staining and 50% showed moderate staining.

This study was conducted to investigate the effects of α-lipoic acid and coenzyme Q10 on plasma levels of lipids, asymmetric dimethylarginine, oxidative stress in fructose fed rats which provide a model of dietary-induced insulin resistance and to evaluate vascular changes developing in these rats by histologically. Male Sprague Dawley rats were used in this study. The animals were divided into 4 groups.

Dynamic computed tomography (CT) and magnetic resonance imaging (MRI) show typical contrast enhancement of SST with peripheral enhancement in the early phase and centripetal progression in the delayed phases.

The aim of the present study is to investigate immunohistochemical hTERT expression and its relationship with the clinicopathologic features in a spectrum of colorectal tumors. In this study, hTERT expression was determined in HP (n = 20), adenomatous polyp (AP) (n = 20), colorectal adenocarcinomas (n = 20), and normal mucosa (n = 20) by immunohistochemical method.
