title: Aneurysmal (angiomatoid) fibrous histiocytoma.
abstract: We report a patient with aneurysmal (angiomatoid) fibrous histiocytoma manifested clinically as a single firm subcutaneous nodule, diagnosed as an epithelial cyst. Histologically, the growth showed massive histiocytic proliferation and areas with a vascular component. The lesion was histologically mistaken for Kaposi's sarcoma.
