A case of malignant fibrous histiocytoma
Abstract
- The malignant fibrous histiocytoma is a predominantly pleomorphic arcoma usually occuring in the deep soft tissue of adults. Because of its highly variable morphologic pattern, this tumor has often been confused with other sarcomas such as pleomorphic rhabdomyosarcoma and liposarcoma. Although the histogenesis of this neoplasm remains controversial, it is best regarded as a primitive and pleomorphic nature reflected by collagen production and occasional phagocytosis. As report a case of malignant fibrous histiocytoma occurring in a 54-year-old female who presented with 4.5 x 5 x 0.5cm sized mass on the right thigh and metastasis later. Histopathologic findings shows plamp spindle cells appearing in a storiform-pleomorphic pattern around slitlike vessels. Immunohistochemical staining and electron microscopic findings led to the final diagnosis as malignant fibrous histiocytoma. The treatment was surgical excision.
