Four cases of Bowen's disease of the nail bed occurred. The clinical appearance of the lesion was characterized by either verrucose hyperplasia, fissures, or ulceration of the nail bed with destruction of the nail plate in the area. Treatment of choice is complete surgical excision of the nail bed and the nail matrix, if it is affected.
