Eccrine syringofibroadenoma radiation treatment of an unusual presentation.

Benign skin diseases have seldom been treated with radiotherapy, unless resistant to other treatments. Eccrine syringofibroadenoma (ESFA) is a rare benign eccrine tumor. ESFA very rarely presents bilateral lesions, and seldom a nonsurgical treatment has been proposed. An exceptional case of bilateral ESFA of the foot is presented; radiotherapy was effective in treating both lesions with good cosmetic results.
