A Case of Generalized Syringoma Misdiagnosed as Verruca Plana / 대한피부과학회지

ABSTRACT

Generalized syringoma is a rare variant of syringoma, whose incidence peaks during childhood and adolescence, with no difference seen in either sex. It frequently affects the chest, neck, abdomen and axilla, and occasionally shows spontaneous regression. A 34-year-old woman presented with pruritic, multiple, 1~3 mm sized, lightbrownish papules on the chest, abdomen, and back. One year before, she had been diagnosed as having verruca plana at a private dermatologic clinic and had received immunotherapy, but experienced disappointing results. Histologically, the disorder showed numerous dilated eccrine ducts lined by two rows of epithelial cells. We herein report a case of generalized syringoma misdiagnosed as verruca plana, plus a review of the literature.
