Syringoma

Syringoma is a benign tumor of the eccrine sweat ducts. It has a chronic course, rarely regresses spontaneously, and generally poses no harm to the patient, so treatment is usually not required. This condition is common in adolescent and middle-aged women. The main symptoms are one or more millet-seed-sized papules appearing on the lower eyelids, face, neck, armpits, and external genitalia.
