A syringoma is a noncancerous tumor of the sweat ducts. Syringomas are most commonly found in clusters on the eyelids, but they may also occur elsewhere on the face, or on the scalp, neck, chest, abdomen, armpits, or groin. They are yellow or skin-colored, small, firm, rounded lumps, and rarely cause any other symptoms, although occasionally they may be itchy.
They are harmless and do not need treatment. They may be removed by heat or laser treatment, but this can leave scars.
