Abstract
Pigmented onychomatricoma (OM) is a very rare benign fibroepithelial tumor of the nail matrix. We report the case of a 23-year-old Lebanese man with 15-year history of nail plate dystrophy with longitudinal ridging, yellowish discoloration, excessive transverse curvature and late-onset melanonychia along the medial third of the right thumb nail. Excisional biopsy was performed and confirmed OM. We outline the clinical history, radiological and histopathological findings as well as the surgical and reconstructive technique of this unusual case of OM. The age group, history of crush injury, and pigmentation of the nail plate make of this rare form of ungual tumor an interesting case report. © 2019 SFCM
