Eccrine syringofibroadenoma arising in peristomal skin: a report of two cases.

Eccrine syringofibroadenoma (ESFA) is a benign neoplasm arising from the intraepidermal portion of eccrine ducts. It is characterized by a distinctive histologic pattern of epithelial cells arranged in anastomosing cords surrounded by a fibrovascular stroma. Approximately 50 cases of ESFA have been reported, and in recent years the lesion has been described occurring in association with other skin conditions. We report 2 cases of ESFA arising in abdominal skin adjacent to enterostomy sites.
