Three subtypes of poroid neoplasia in a single lesion: eccrine poroma, hidroacanthoma simplex, and dermal duct tumor.
Four histopathologic variants of poromas are accepted, according to the architectural features of the neoplasm: hidroacanthoma simplex or intraepidermal poroma; eccrine poroma, which is a poroma connected to the epidermis that extends to superficial dermis; dermal duct tumor, which develops when the neoplasm is composed of small, solid aggregations of poroid and cuticular cells confined to the dermis with little or no connection with the epidermis; and poroid hidradenoma, which is a solid-cystic, dermal poroma (2).
It has also been described as malignant hidroacanthoma simplex, sweat gland carcinoma, malignant intra-epidermal eccrine poroma, eccrine poro-epithelioma, dysplastic poroma, malignant syringoacanthoma and porocarcinoma.
DISCUSSION: Malignant eccrine poroma may be seen associated with an eccrine poroma or a lesion of hidroacanthoma simplex.
