A Case of Atypical Linear Porokeraotsis / 대한피부과학회지

ABSTRACT

Porokeratosis is a familial, chronic, progressive disorder which demonstrates a characteristic clinical and histologic picture. Since Mibelli described three cases in 1893, several clinical variants have been identified, all of which are delineated by a diagnostic histopathologic pattern. We reported a case of atypical linear porokeratosis that had three types of skin lesions. One was the plaque type, as originally described by Mibelli. And others were atypical lesions, as papules and verrucoid hyperkeratotic plaques.
