Fibroma of tendon sheath in the hand.

Seven cases of fibroma of tendon sheath in the hand are reviewed. These tumors are common enough to be considered in the differential diagnosis of a soft tissue tumor in the hand, as they comprised 7 of our series of 208 soft tissue hand tumors excised over a 15-year period. A marginal excision was performed in each case, and no tumor recurred after a mean follow-up interval of 8 years. The fibromas were adherent to tendons, tendon sheaths, and neurovascular structures, and thus were more difficult to excise without morbidity than other soft tissue hand tumors.
