Malignant fibrous histiocytoma in a child's hand.

ABSTRACT

A 3-year-old girl had a 4-month history of a tumor in her right hand. The tumor was located in the subcutaneous and soft tissues of the palm and the long, ring, and small fingers. Histologic studies showed a malignant fibrous histiocytoma that was confirmed by the ultrastructural study as having a fibroblastic and histiocytic origin. The long, ring, and small fingers were amputated. The postoperative course was normal, and 18 months later no recurrence or metastases were observed.
