Coexistence of Linear Porokeratosis with Disseminated Superficial Actinic Porokeratosis / 대한피부과학회지

ABSTRACT

The coexistence of the variants of porokeratosis is very rare. We report a case of coexistence of linear porokeratosis with disseminated superficial actinic porokeratosis (DSAP). A 43-year-old wornan first noticed a brownish papule on the left side of groin in early infancy. She developed multiple discrete or confluent keratotic plaques in linear fashion on the left lower extrernity and trunk in childhood. These leaions became pruritic in summer. Two years ago, she developed multiple scattered small annular lesions on the face and forearms. Her family history showed no abnormalities. Biopsy specimene from the groin and trunk showed eornoid lamella.
