Fibroma of Tendon Sheath Revisited.

Fibroma of tendon sheath (FTS) is a benign fibroblastic/myofibroblastic neoplasm that primarily occurs in the fingers and hands of young and middle-aged adults. The lesion typically presents as a small, firm, slow-growing, painless nodule. Ultrasonography usually shows a focal nodular mass with homogeneous hypoechogenicity.
