Squamous cell carcinoma of the nail bed is a rare malignant tumor. The highest incidence occurs in the fingernails of the hand, but involvement of the toenails is also possible. Subungual squamous cell carcinoma often resembles to other more common benign lesions, such as fungal infections, onychomycosis, or viral warts, which explains the frequently delayed diagnosis of this tumor. We report the case of a mason with a subungual squamous cell carcinoma of the right hallux that had developed in a chronic post-traumatic lesion, without bone invasion. Treatment consisted of toe amputation. Further attention to chronic non-healing nail bed lesions is needed.
