Abstract
Thirteen cases of fibroma of tendon sheath have been reviewed. This lesion presents predominantly in middle-aged adults, particularly men, and usually arises in the dermis and subcutis of the extremities, most especially the hands. Histologically these tumours are always well circumscribed and may be lobulated. They are largely composed of interlacing bundles of hyalinised, hypocellular fibrous tissue with occasional more cellular areas. A constant feature is the presence of slit-like vascular channels. They are benign lesions with little tendency to recur and, although becoming more generally recognised are not yet familiar to dermatologists.
