We investigated the rates of expression of bone morphogenetic protein-2 (BMP-2) in 29 adult patients with high-grade malignant fibrous histiocytoma of soft tissue, using the BMP-2-specific monoclonal antibody, AbH3b2/17, and found that they ranged from 1.9% to 78.9%. The survival at five years of the groups expressing high (> or = 30%) and low (< 30%) levels of BMP-2 was 85.7% and 36.3%, respec...

Malignant fibrous histiocytoma of the thoracic aorta associated with ulcer-like projection has not been reported previously. The hypovascular tumor of the thoracic aorta involved the mural layer, which showed intra- and extra-mural growth patterns and no significant filling defect within the aortic lumen, and mimicked ulcer-like projection with secondary pseudoaneurysm formation. Aortic tumor, ...

The light microscopic and immunohistochemical characteristics of a case of fibrous histiocytoma of intermediate malignancy arising from the parotid gland are presented. This neoplasm is rare in this site and must be distinguished from other spindle cell tumors of the parotid gland, particularly those of epithelial and myoepithelial origins. Histologic characteristics similar to those displayed ...

Angiomatoid fibrous histiocytoma is an uncommon soft-tissue tumor of intermediate malignancy that is often misdiagnosed initially. As there is not one immunohistochemical marker that consequently stains positive or negative for angiomatoid fibrous histiocytoma, molecular diagnostics are becoming more widely used. So far three translocations have been reported to arise in angiomatoid fibrous his...

INTRODUCTION Malignant fibrous histiocytoma is a very common subtype of soft-tissue sarcoma in middle and late adulthood. However, malignant fibrous histiocytoma of the testis is very rare in adolescents. CASE PRESENTATION We report here the case of a 14-year-old Han Chinese boy, who presented with left scrotal mass lasting for 20 days along with distending pain for 5 days. A physical examina...

background &amp; objective: chronic non healing ulcers or scar undergoing malignant transformation is a rare phenomenon with an estimated incidence of 2%. though, numerous predisposing factors have been identified, still it is rarely diagnosed and commonly mistaken for a benign condition. the objective of this study was to verify the efficacy of the fine needle aspiration cytology/ scrape cytol...
