[ 4 ] - Evaluation of Phenotypic Characteristics of 53 Cases of Neurofibroma in Hazrat Fatemeh Hospital during the Years 1994-2005
Background and Objective: Neurofibromas occur as solitary and multiple forms. The solitary ones are extraneural and more common, histologically exhibiting spindle cells with wavy nuclei, scattered among collagen fibers.

[ 6 ] - Differential diagnosis of urothelial carcinoma in situ from non-neoplastic urothelia: Analysis of CK20, CD44, P53 and Ki67
Background: Flat urothelial lesions comprise a spectrum of morphologic changes ranging from reactive atypia to carcinoma in situ (CIS). Urothelial dysplasia and CIS are associated with the recurrence and progression of urothelial carcinoma. Distinguishing CIS and dysplasia from reactive atypia based on histolopathogical features alone is often difficult. Using different immunohistochemical mark...
[ 7 ] - Well differentiated liposarcoma of spermatic cord: report of 3 rare cases
Spermatic cord liposarcomas are very rare tumors. Patients usually present with painless growing scrotal swellings which are clinically misdiagnosed as hernia. The correct diagnosis is not common and usually they present as operative or histological surprises. To our knowledge, there are about 186 similar cases reported in the literature. Herein we report three cases of spermatic cord li...
[ 8 ] - Platelet count and MPV, routinely measured but ignored parameters used in conjunction with the diagnosis of acute coronary syndrome: single study center in Iranian population, 2010
Background: Myocardial infarction is the major cause of morbidity and mortality in industrialized countries. Platelet count and the mean platelet volume (MPV), a simple and reliable indicator of platelet size which correlates with platelet activation, might associate with troponin in acute chest pain. Methods: We analyzed MPV of 851 patients who were admitted to Rasoul-e-Akram Hospital with ac...
[ 9 ] - A Rare Case of Duplication of Chromosome 2 (q31.3q36.3) in a 4.5-year-old Boy and Review of the Literature
De novo duplication of 2q is very rare. Most cases of 2q duplications result from familial translocations, and are associated with simultaneous monosomy of another chromosome segment. To our knowledge and search in English literature there are less than 20 reported cases of isolated 2q duplication. Hereby we introduce a 4.5-year-old Iranian boy of a non-consanguineous marriage who was referred ...
