Bowen's disease of the nail apparatus: a series of 8 patients and a literature review.

Bowen's disease of the nail apparatus is uncommon. Since often characteristic clinical features are missing, diagnosis and treatment are delayed. We have analyzed our patients' files from January 2001 to July 2015 for this disorder. We identified eight patients with Bowen's disease of the nail apparatus, six male and two female individuals. Fingers were more often affected than toes. The disease does not respect the anatomical borders of the nail apparatus. Therefore, we performed delayed Mohs surgery with skin grafts in seven patients and with second intention healing in one patient. Two relapses were noted but only one ate the same digit. Since relapses occurred after 2-3 years, a follow-up of such patients seems justified.
