Abstract
- Acantholytic acanthoma is a rare benign neoplasm of epidermal keratinocytes and this commonly displays as a solitary, asymptomatic keratotic papule on the trunk. The histologic features are hyperkeratosis, acanthosis, papillomatosis and prominent acantholysis. Dyskeratotic cells are occasionally present, but prominent dyskeratosis is not a characteristic feature of acantholytic acanthoma. Herein, we report on a case of acantholytic acanthoma with several dyskeratoses, and this occurred in a 54-year-old woman who presented with a keratotic plaque that repeatedly pealed on the umbilicus.
