Fibro-osseous pseudotumor on the hyponychium of the great toe

Abstract

Fibro-osseous pseudotumor of the toe is a benign soft tissue tumor that is predominant in the young adult population. Although the etiology is unknown, a history of trauma has been reported to precede tumor development. The differential diagnosis includes myositis ossificans, extraskeletal osteosarcoma, and pyogenic granuloma. Once removed, the tumor typically has no recurrence. Surgical excision is the treatment of choice. We present a patient with fibro-osseous pseudotumor of the great toe, which had no recurrence following excision.
