단순 한선 극세포종 1예 = A Case of Hidroacanthoma Simplex

다국어 초록 (Multilingual Abstract)

Hidroacanthoma simplex is a rare skin tumor which most often develops on the lower extremity of an elderly person. Clinically, the lesion appears as a well-demarcated brownish flat or verrucous plaque, resembling seborrheic keratosis or Bowen's disease. Histologically, it is characterized by intraepidermal nests of basaloid cells within an acanthotic epidermis. there is some controversy over the histogenesis of hidroacanthoma simplex, many consider it an epidermal tumor differentiation into intraepidermal eccrine duct cells. We report a case of hidroacanthoma simplex presented a small verrucous papule on the left foot with the results of an immunohistochemical study.
