A Case of Darier-like Actinic Keratosis / 대한피부과학회지

ABSTRACT

A 82-year old man was presented with a 0.7 by 0.5 cm sized, atrophic, mild erythematous macule on the left temple for 4 months. There was no history of verruca on the lesion or taking arsenic. Histopathologically, there were suprabasal acantholysis, lacunaes, vesicles with a few corps ronds and grains in the suprabasal layer and granular layer. Atypical cells and dyskeratotic cells were, in groups, seen in the entire epidermis and its appendages. But, glandular structures were not found. We report a rare case of actinic keratosis showing Darier-like features.
