Abstract:
We report a case of hidroacanthoma simplex on the inframammary area of an 86-year-old woman. The tumor cells showed considerable variation in appearance in different nests from the same lesion. By light and electron microscopy 5 types of tumor cells were identified. This tumor was thought to originate from the outer cells of the intraepidermal eccrine duct.
