Pseudosarcomatous fibromyxoid tumor (PSFT) is a rare pseudotumor of the genitourinary (GU) system that typically presents with gross hematuria. These tumors are benign, locally aggressive tumors. Metastasis has never been reported. Pathology is significant for spindle cell proliferation without malignant nuclear features that are commonly seen in sarcomas. Herein, we report a case of an 8-centi...

Inflammatory myofibroblastic tumors are neoplasms characterized by spindle cell proliferation and a fiboinflammatory vascular stroma. Herein, we presented the successful treatment of a rectal inflammatory myofibroblastic tumor in an 11-year-old boy who presented with diarrhea and abdominal pain of 1(1/2) months duration and an appendiceal inflammatory myofibroblastic tumor in a 29-year-old man ...

Human Bub1 plays an important role at the spindle assembly check-point to prevent cell cycle progression following spindle damage. We examined the expression of Bub1 mRNA and protein in 21 human salivary gland tumors (7 pleomorphic adenomas, 2 warthin tumors, 5 mucoepidermoid carcinomas, 3 adenoid cystic carcinomas and 4 acinic cell carcinomas) and 3 normal submandibular glands using real-time ...

Spindle cell lipoma is a histologically distinct variant of lipoma characteristically arising in the subcutis of the posterior neck, upper back, or shoulder. Spindle cell lipomas infrequently occur within the oral cavity and, in particular, rarely involve the tongue. The clinical and pathologic features of eight cases of spindle cell lipoma affecting the tongue were analyzed. The study group in...

leydig stromal cell tumor is a rare ovarian tumor that belongs to the group of sex-cord stromal tumors. they produce testosterone leading to hyperandrogenism. we present a 41yr old woman with symptoms of virilization and a mass of right adenex via ultra sonography, and a rise of total and free serum testosterone. an ovarian source of androgen was suspected and a surgery performed. a diagnosis o...

INTRODUCTION We present the immunohistochemical (IHC) analyses of a series of four kidney tumors currently classified as mucinous tubular and spindle renal cell carcinoma (WHO), a tumor with uncertain histogenesis and differentiation. Our aims were to determine an immunoprofile and to add clinical and morphological information about this rare renal carcinoma. MATERIAL AND METHODS The four tum...
