Abstract:
We report a review of the morphologic and topographic characteristics of 176 cases of cutaneous fibrous histiocytoma. We confirm its prevalence in females with greater incidence of location in the limbs. Among the morphologic varieties the most frequent is the fibro-collagenous. The most common differential diagnosis comprises dermatofibrosarcoma protuberans, atypical fibroxanthoma, malignant fibrous histiocytomas and idiopathic fibromatosis. Its histogenesis from mesenchymal immature elements and its tendency toward fibrohistiocytic differentiation is generally accepted.
