A rare case of fibroma of a tendon-sheath of the fourth toe: A case report

Fibroma of the tendon sheath (FTS) arising from the extensor tendon of a toe is a rare event. A review of the literature reveals less than 10 such cases. The current case report describes such a very rare tumor arising from the extensor digitorum longus tendon in a 61-year old male patient. The patient presented with a 6-month history of a progressive localized swelling of his left fourth toe. The tumor was diagnosed based on clinical, radiographic, surgical and histopathologic findings. By presenting this case report, the authors hope to call attention to this rare condition as a possible differential diagnosis in patients presenting with a soft tissue mass involving the toes.
