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.
