Abstract
- Hidroacanthoma simplex is a rare, benign intraepidermal skin tumor originating from eccrine ducts. It usually develops on the lower extremity or trunk of the elderly, and appears as a well-demarcated brownish to erythematous flat or verrucous plaque. It is often clinically misdiagnosed as seborrheic keratosis or Bowen's disease and the pathogenesis of the disease is not understood. Histopathologically, it shows characteristic intraepidermal nests not extended to the dermis, the so called Borst-Jadasshon phenomenon. The nests are composed of uniform cuboidal tumor cells with a round, basophilic nucleus. Here we report a case of hidroacanthoma simplex following burn injury in an 82 year-old woman.
