Adrenal PEComa Treated by Surgical Resection and Postoperative Radiotherapy: A Case Report.

BACKGROUND Perivascular epitheloid cell neoplasm (PEComa) is a rare mesenchymal tumor that is evaluated in the same tumor family as angiomyolipoma, sugar cell tumor of the lung, and lymphangioleiomyomatosis. Immunohistochemically, the disease can express melanocytic and myogenic markers, such as HMB45, HMSA1, MelanA/Mart1, and actin. The disease can be seen in almost every organ, especially the uterus and retroperitoneum.

A clinicopathological experience in acute myeloid leukemia: Effects of clinical data and status of FLT3, CEBPA and NPM1 on prognosis.

Background: The purpose of the study was to analyze the expression of nucleophosmin (NPM1), CCAT/enhancer-binding protein alpha (CEBPA), and FMS-like tyrosine kinase 3 (FLT3) with immunohistochemistry and evaluate the relationship with clinicopathologic data with special emphasis on prognosis in bone marrow biopsy specimens diagnosed with acute myeloid leukemia (AML).

Materials And Methods: Bone marrow biopsies of 104 patients who were diagnosed with AML were re-evaluated for diagnosis and subclassification. Immunohistochemically, anti-NPM1, anti-CEBPA, and anti-FLT3 antibodies were applied to slides prepared from formalin-fixed paraffin-embedded tissues.

The Effect of Intraarticular Insulin on Chondral Defect Repair.

Objective: The aim of this study is to evaluate the effects of intraarticular insulin on the treatment of chondral defects.

Design: Twenty-four mature New Zealand rabbits were randomly divided into 3 groups as control (Group 1), microfracture (Group 2), and microfracture and insulin (Group 3). Four-millimeter full-thickness cartilage defects were created to the weight-bearing surface on the medial femoral condyles of each rabbit.
