title: Fibroma of tendon sheath.
abstract: This report describes a 60-year-old woman with a fibroma of tendon sheath of left hand. Ultrastructural study of the tumor reveals the nature of the tumor cells as fibroblasts, thus distinguishing it from the more common giant cell tumor of tendon sheath believed to be derived from synovial cells.
