A Case of Papillary Eccrine Adenoma / 대한피부과학회지

ABSTRACT

The papillary eccrine adenoma is a rare benign sweat gland neoplasm, first described by Rulon and Helwig in 1977. It is usually present as a solitary dermal nodule on the distal extremities. Histological examination revealed a well circumscribed, non capsulated dermal nodule consisting of multiple ducts with various size. These ducts were composed of double layered epithelial cells mostly and intraluminal papillation with eosinophilic luminal materials was seen. We report a case of papillary eccrine adenoma in 52-year-old male who presented single nodule on the right midback, uncommon area.
