Nevoid basal cell carcinoma syndrome and acrokeratosis verruciformis. Occurrence of two rare inherited autosomal dominant conditions in the same patient.

An exceptional case of nevoid basal cell carcinoma (NBCC) syndrome occurring with acrokeratosis verruciformis (AKV) in the same patient is presented. The occurrence of two rare autosomal dominant diseases in a patient suggests that AKV might be one of the different dyskeratoses of the NBCC syndrome. The clinical aspect of the flesh-colored papules of AKV, indistinguishable from flat warts, might nevertheless prompt performance of a biopsy.
