다발성으로 발생한 거대한공각화증 1예

Abstract

We report a case of an 81 year-old man with multiple, giant porokeratosis, who had variable-sized erythmatous, scaly plaques, ranginh from 3*4 cm to 10*12cm, on, his trunk, extremities and genital area. The skin lesions appeared 20 years ago and had increased gradually and slowly, both in size and number. Histologic examination revealed a typical cornoid lamella and loss of the underlying granular layer. Giant porokeratosis was diagnosed on the basis of overwhelming clinical features and characteristic histologic findings. Giant porokeratosis is a rare clinical condition among several subtypes of porokeratosis.
