Hidroacanthoma simplex

摘要：

From the low-power biopsy specimen,we found hyperkeratosis and acanthosis with some lymphocytes which looks like Seborrheic Keratosis (SK) (Figure 1).At high-power,we observed well-circumscribed intraepidermal nests of clear-looking basaloid cells within the confines of an acanthotic epidermis (Figure 2),and the tumor cells were small and relatively monomorphic,cellular and nuclear atypia was not prominent (Figure 3).Finally,we made the diagnosis of hidroacanthoma simplex.Smith & Coburn first introduced the term hidroacanthoma simplex in 1956 to refer to an intraepidermal variant of poroma”1”.The histopathologic findings of hidroacanthoma simplex are cuboidal or ovoid deratinocytes with a vesicular nucleus within an acanthotic epidermis arranged in well-circumscribed intraepidermal nests,with or without presence of the ductal and cystic space.
