A case of solitary eccrine syringofibroadenoma

Abstract

Eccrine syringofibroadenoma (ESFA) is a rare, benign adnexal neoplasm of eccrine ductal differentiation. It shows variable clinical findings ranging from a solitary papule or nodule to multiple lesions withlinear or diffuse distribution. Typically, it occurs as a solitary nodule on the extremities of elderly people. Histopathologic findings usually show proliferation of anastomosing cords and strands of cuboidal epithelial cells embedded in fibrovascular stroma. We report an uncommon case of solitary eccrine syringofibroadenoma with plasma cell infiltration on the dorsum of the foot of a 53-year-old man.
