Eccrine syringofibroadenoma: an unusual presentation of a rare disease

Eccrine syringofibroadenoma [ESFA] is a rare disorder with differentiation towards ductal eccrine apparatus. There are a variety of clinical manifestations and distribution of lesions but the histopathological features are remarkably similar with benign appearing anastomosing cords of eccrine ductal epithelial cells with or without lumina formation, are embedded in loose fibrovascular stroma. We report a case of 55-year-old Muslim man having large pale pink slightly verrucous plaque on right upper back since last 20 years with central ulceration for 8 years.
