A 78-year-old man presented with asymptomatic multiple skin-colored hard plaques and nodules over the dorsa of both feet progressively increasing in size and number over the duration of 10 years [Figure - 1]. Histopathologic examination revealed a tumor composed of thin, anastomosing epithelial cords embedded in a fibrovascular stroma. The epithelial strands were composed of mature acrosyringeal cells and had eccrine ducts. Immunohistochemistry showed positive epithelial membrane antigen staining of the tumor cells and positive carcinoembryonic antigen staining of the ductal lumina. Dermoscopic examination was not done. A diagnosis of eccrine syringofibroadenomatosis was made. It is an uncommon tumor of the acrosyringium. Considering its malignant potential, complete excision is recommended. If complete excision is difficult due to involvement of larger areas, close surveillance and biopsies are necessary.
