background and aims. well-differentiated chondrosarcoma and enchondroma are similar in histopathologic aspects; therefore, special methods should be used to make a distinction between these benign and malignant tumors. the aim of this study was to evaluate the efficacy of a histopathologic method in the long-term follow-up for differentiating these lesions. materials and methods. the medical re...
Background and Objective: One important step in the management of gastric cancer is determination of its prognosis. Cytokeratins are intermediate filaments that mainly exist in cytoskeletal component of epithelial cells. Recent researches have focused on the relationship between the expression of different cytokeratins with differentiation and outcomes of tumors. This study was done for determ...
Background and Objective: Adenoid cystic carcinoma (ACC) and polymorphous low grade adenocarcinoma (PLGA) originate from ductal and myoepithelial salivary gland cells. They have a similar histologic appearance, but with different clinical behavior, treatment and prognosis. CD117 is a tyrosine kinase that is expressed by melanocytes, mastocytes and germinal cells. Our knowledge about its express...
Ameloblastic carcinoma is an extremely rare malignant neoplasm which mostly occurs in the mandible and at a wide age group. It has no gender bias and has specific histopathologic features and its surgical treatment requires more aggression than ameloblastoma. . The number of reported cases of the disorder are rare, and it is very difficult to diagnose based on histopathologic findings because t...
Background & Objective: The role of synchronized expression pattern of cytokeratin (CK) 7 and CK20 in the prognosis of colon adenocarcinoma is unclear. The current study aimed at determining the relationship between the expression of cytokeratins 7 and 20 and prognostic factors in colon adenocarcinoma. Methods: In the current cr...
Immunohistochemical reactivity with OKT9 (antitransferrin receptor) monoclonal antibody was studied in 58 surgically resected adenocarcinomas of the lung. The cell surface and cytoplasm of the tumor cells were stained in 44 cases (76 percent). The expression of the transferrin receptor (TrfR) in tumor cells was compared with histopathologic prognostic factors, such as TNM factors, degree of his...
Background & Objective The role of synchronized expression pattern of cytokeratin (CK) 7 and CK20 in the prognosis of colon adenocarcinoma is unclear. The current study aimed at determining the relationship between the expression of cytokeratins 7 and 20 and prognostic factors in colon adenocarcinoma. Methods In the current cross sectional Study, 52 archival samples of colon adenocarcinoma wi...

Background: Skin adnexal tumors are a spectrum of benign and malignant that differentiate toward or arise from the unit skin. These rare pose challenge in diagnosis, often, discrepancy is seen between clinical histopathological diagnosis. Materials methods: This single institutional study was carried out among 36 patients who presented with swelling. An initial diagnosis considered based on his...
Reticulated acanthoma with sebaceous differentiation (RASD) is a rare, benign cutaneous tumor with peculiar histopathologic characteristics [1]. RASD had been described under various synonyms such as superficial epithelioma with sebaceous differentiation, sebocrine adenoma, poroma with sebaceous differentiation, and seborrheic keratosis with sebaceous differentiation [2]. Clinical differential ...
