BACKGROUND A better understanding of the histopathology and molecular biology of lung cancer might improve our capability to predict the outcome for any individual patient. The purpose of this study was to evaluate several histopathologic and molecular markers in order to assess their prognostic value in stage I non-small cell lung cancer. MATERIALS AND METHODS One hundred ten patients at the...

Background: The incidence and mortality rates of salivary gland tumors have increased according to previous evidence. No study has so far focused on the trend clinical histopathologic patterns in Iran. Therefore, aim was investigate clinico-histopathologic a retrospective, cross-sectional, institutional from 2010-2019 Amir Alam hospital. Methods: archived medical records were collected patients...

Background: New blood vessels formation is a critical step in tumor progression. Vascular density affects the clinical outcome and prognosis of malignant tumors. The aim of this study was to investigate the relation between the Vascular Endothelial Growth Factor (VEGF) expression and vascular density with the clinical and histopathologic features in oral squamous cell carcinoma (OSCC). &nbsp...

Sclerosing epithelioid fibrosarcoma (SEF) is a clinicopathologically distinct variant of fibrosarcoma that is capable of recurrence and metastasis. Awareness of imaging features and histopathologic characteristics will be helpful for differential diagnosis from other common tumors. Here, we report a case of SEF metastasizing to the pancreas as a solitary mass mimicking primary pancreatic cancer...

introduction: oral lichen planus (olp) and oral lichenoid lesions (olls) are clinically and histopathologically similar lesions but with different etiologies and treatment plan, thus differentiatingthese two has been the center of many researches. studies in different populations have beenperformed on clinical and histopathologic features of olp and olls. thus aim of the present studywas to eva...

Cranial fasciitis is an uncommon benign disorder characterized by a fibroblast-like cell proliferation, observed almost exclusively in children. Clinically, it manifests as a rapidly growing, solitary nodule in the head or neck area. Underlying bone involvement (cranial cortical erosion) is frequently detected. Histopathologic analysis allows differentiation between cranial fasciitis and fibroh...

primary pancreatic lymphoma is a rare extranodal manifestation of any histopathologic subtype of b cell non-hodgkin's lymphoma that predominantly involves the pancreas. it comprises less than 0.2% of pancreatic malignancies and less than 0.7% of non-hodgkin's lymphomas. this lymphoma is almost never suspected clinically. it is usually diagnosed by surgical exploration for suspected ad...

inflammatory pseudotuomr refers to a group of benign tumor like lesions that they are composed of a mixed inflammatory infiltrates. the diagnosis of these lesions and differentiation of them from malignant process may be difficult. we report on a 35-year- old man who presented with multiple painless palpable masses in his right hemiscrotum for about 6 months. right epididymal involvement with i...

INTRODUCTION Basal cell adenoma (BCA) of the salivary glands is a rare benign salivary gland tumour. Differentiation of BCA from varied entities involving maxillofacial area is mandatory. AIM To analyze the clinicopathological, histopathologic features, immunohistochemcal analysis and surgical considerations of this rare entity. MATERIALS AND METHODS This study included 12 cases of BCA from...
