Bowen's disease and squamous cell carcinoma of the palm.

A case of Bowen's disease of the palm with associated squamous cell carcinoma is described. A brief general review underlines this unusual localization. Bowen's disease may occur at any cutaneous site, simultaneously involving areas protected from and exposed to the light. Involvement of the dorsum of the hand is not rare, but palmar involvement is highly unusual. Only 12 indisputable cases have been published up to the present time.
