Onychomatricoma an infrequent nail tumor: Two case reports

Purpose: Onychomatricoma is an uncommon but benign neoplasm of the nail matrix that has been rarely reported in literature and often misdiagnosed. Fewer than 100 cases have been reported, and multiple tumors were initially misdiagnosed and treated as primary onychomycosis. It predominantly affects women (2-16:1) with a peak incidence in the fifth decade with only one pediatric case ever been reported. It is most commonly seen in Caucasians and has a predilection for fingers rather than toes. The classic clinical signs of OM include xanthonychia, nail plate hypertrophy, splinter hemorrhages, transverse overcurvature of the nail plate, and woodworm-like cavities of the nail plate.
