A 54-year-old woman had noticed a nodule on her thigh 6 years ago. The nodule was excised three times because of reccurrence. In April 2000, 4th reccurence occurred. At this time, she consulted a dermatologist who suspected the lesion to be a malignant tumor; subsequently, she was referred to us. The nodule was excised completely. Histopathologically, the tumor was composed of spindle-shaped cells mixed with bizarre giant cells. In some areas of the lesion, the tumor cells were arranged in a storiform pattern, and in other areas chondroid tissue had formed. Immunohistochemically, the tumor cells revealed a variety of findings. Electron microscopy did not show that the tumor cells had characteristic ultrastructural features. Thus we diagnosed this tumor as malignant fibrous histiocytoma, pleomorphic type. [Skin Cancer (Japan) 2002; 17: 61-64]
