Congenital agminated segmental nevi of the chest.

Grouped patterns of pigmented lesions are infrequent. Of the several reports of agminated nevi, most have been Spitz nevi or blue nevi. The distribution of these nevi is often segmental, following a dermatome or the lines of Blaschko. Most segmental nevi are not agminated and develop early in childhood [1]. We describe a rare case of congenital agminated segmental nevi on the chest.
