A Case of Vesicular Prurigo Pigmentosa / 대한피부과학회지

ABSTRACT

Prurigo pigmentosa (PP) is a rare inflammatory skin disease of unknown etiology, characterized by recurrent, symmetrical, pruritic, erythematous papules resulting in gross reticular hyperpigmentation. The rash occurs mainly on the back, the chest and the nape of the neck. Vesicular or bullous forms have been reported only rarely. This case report concerns a 15-year-old female with PP, in whom vesicular manifestations appeared recurrently on an existing maculopapular eruption on the trunk.
