Onychomatricoma: A Rare and Potentially Underreported Tumor of the Nail Matrix

Onychomatricoma is a rare benign neoplasm of the nail matrix first described by Baran and Kint in 1992. Fewer than 80 cases of onychomatricoma have been described in the literature, 15 of which were initially misdiagnosed and treated as onychomycosis. We present the case of a 66-year-old male with thickening and linear xanthonychia of the hallux nail plate secondary to an onychomatricoma misdiagnosed as onychomycosis
