Background: Solitary trichoepithelioma is a rare benign tumor of hair follicle origin. Although has predilection for the face and neck, it not usually found on eyelids. It similar clinicopathological features to basal cell carcinoma. Surgical excision histopathologic analysis helpful correct diagnosis. Case Report: A 59-year-old Caucasian female presented with raised, reddish oval mass right lo...

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...

Paragangliomas are neoplasms of neural crest origin. In the head and neck, they uncommonly involve the larynx. The distinction between paragangliomas and other neuroendocrine tumors can be difficult. Precise diagnosis is important in order to optimize patient treatment. Diagnosis relies mostly on histopathologic examination followed by immunohistochemistry. Here we report a 77-year-old woman wi...

BACKGROUND The recognition, terminology used and histopathologic evaluation of two essential elements in gastric carcinogenesis, atrophy and dysplasia, are characterized by controversy. MATERIALS AND METHODS One hundred fifteen cases, with slides and their histopathologic reports from the archive of the Laboratory of Pathology were studied for the diagnostic value, reporting of dysplasia, int...

sarcoidosis is multi organ disease with cutaneous manifestation in 20%-35% patients. cutaneous sarcoidosis has variable manifestations that make it difficult to diagnose. so clinical, histopathologic and laboratory evaluation is needed for diagnosis. most of cutaneous lesions presents as nodul, maculopapule and plaque. morpheaform lesion is a rare presentation of cutaneous sarcoidosis. this cas...

Iris varix is rare and little is known about its clinical characteristics. We treated a thrombosed iris varix that simulated an iris melanoma. A 53-year-old man developed a dark brown iris mass and hyphema in his left eye. Ultrasound biomicroscopy revealed a circumscribed mass of the iris stroma. Because of suspicion for melanoma, it was removed by sector iridectomy. Histopathologic examination...

Echocardiography is the preferred initial imaging method for assessment of cardiac masses. Cardiac magnetic resonance (CMR) imaging, with its excellent tissue characterization and wide field of view, may provide additional unique information. We evaluated the predictive value of echocardiography and CMR imaging parameters to identify tumors and malignancy and to provide histopathologic diagnosi...
