Bowen's disease of the nail bed: A case report

We present a case of Bowen's disease of the nail bed in a 32-year-old patient admitted to the traumatology-orthopedics department for a persistent lesion of the right thumb nail. Bowen's disease is often misdiagnosed because of its benign, slowly progressive appearance. The clinical picture of this disease is not uniform and can mimic a number of other dermatological disorders, such as vulgar warts, onychomycosis and various clinical presentations. Therefore, biopsy of any chronic nail tissue lesion is essential. Surgical excision is the treatment of choice for tumours without bone involvement. Our patient was treated with Mohs micrographic surgery. Postoperatively, the patient noticed a sensation of hypoesthesia in the treated area, which regressed almost completely over the following months.
