INTRODUCTION Atypical melanocytic nevi are acquired melanocytic lesions that were described for the first time by Clark in studies of melanocytic nevi in patients with melanomas. Today, the use of dermatoscopy has made identification of this type of nevus much easier. OBJECTIVE Our aim was to study the correlation between the clinical, dermatoscopic, and histopathologic findings of melanocyti...

Background: Approximately 0.77% to 2% of cutaneous ulcers and post-burn scars will develop malignant degeneration. When squamous cell carcinoma (SCC) emerges in a chronic scar or ulcer, it often is referred to as Marjolin’s ulcer (MU). Methods: This cross-sectional study assessed demographic information and pathological features of MU in Razi Hospital during 2009 to 2014. We reviewed 5150 chron...

Appendiceal neoplasms include a heterogeneous group of epithelial and nonepithelial tumors that exhibit varying malignant potential. This review article summarizes current diagnostic criteria, classification systems, optimal therapeutic strategies for the five main histopathologic subtypes appendiceal neoplasms. In particular, management has evolved. Although their treatment historically been e...

BACKGROUND To evaluate the correlation of magnetic resonance imaging (MRI) features of breast lesions of Breast Imaging Reporting and Database System (BI-RADS) category 4 with histopathologic results. MATERIALS AND METHODS In a prospective study between December 2013 and April 2015, patients with suspicious mammographic and/or ultrasound findings referred for Breast MRI were evaluated. Patien...

PURPOSE To retrospectively compare pure pulmonary ground-glass opacity (GGO) nodules observed on thin-section computed tomography (CT) images with histopathologic findings. MATERIALS AND METHODS The institutional review board approved this study and waived informed consent. Histopathologic specimens were obtained from 53 GGO nodules in 49 patients. CT scans were assessed in terms of nodule si...

OBJECTIVE To evaluate the characteristics of patients who underwent surgery due to the presence of a large pelvic-abdominal mass over a 5-year period in a university clinic. MATERIAL AND METHODS Among 3476 gynecologic operations, intraoperative findings were evaluated retrospectively. Uterine and/or adnexal masses smaller than 20 cm were excluded to refine "large" tumors and 74 patients with ...

INTRODUCTION Cutaneous leiomyosarcoma is a malignant neoplasm derived from smooth muscle cells. Its low incidence hampers the development of specific protocols for diagnosis and treatment. OBJECTIVES To describe the clinical and histopathologic characteristics of a series of primary and secondary cutaneous leiomyosarcomas and to determine how these characteristics correlate with prognosis. ...

introduction: the purpose of this study was to compare the histopathologic reaction of four suturing materials: silk, polyvinylidene fluoride (pvdf), polyglycolic acid, and catgut in the oral mucosa of albino rabbits. materials and methods: the twenty-one male mature albino rabbits which were used in this study were randomly divided into three groups of seven each. silk, pvdf, polyglycolic acid...
