A Case of Intraepidermal Epithelioma Showing Dermal Invasion / 대한피부과학회지

ABSTRACT

Intraepidermal epithelioma is a rare cutaneous neoplasm characterized histologically by intraepidermal collections of malignant appearing keratinocytes preserving the epidermal architecture. In our case, the tumour unusually showed parakeratosis and dermal invasion. There were a few reports which exhibited parakeratosis and invasion. So, we suggest there may be correlation between these factors.
