Syringoma - External and Internal Eye
See also in: Overview,AnogenitalAlerts and Notices
Synopsis
Syringomas are benign adnexal tumors derived from intraepidermal luminal cells of eccrine sweat ducts. They present as small, dome-shaped papules, often in a periorbital distribution. They may, however, occur at any site on the body. They are seen more frequently in women and in those with Down syndrome. Although usually sporadic, familial cases have been reported and inherited in an autosomal dominant manner. Treatment of these lesions is cosmetic.

Differential Diagnosis & Pitfalls
- Basal cell carcinoma – Pearly papule with telangiectasia and erosions on a background of sun-damaged skin.
- Milia – Small, white cystic papules filled with keratin.
- Xanthelasma – Favor upper eyelids; white to yellow plaques.
- Sebaceous hyperplasia – Yellow umbilicated papule with crown vessels.
- Steatocystoma multiplex – White to yellow smooth papules and nodules.
- Flat warts – Characteristically flat-topped papules.
- Trichoepitheliomas – Favor alar creases; flesh-colored, rubbery papules.
- Trichilemmomas – Common on the lips; may be verrucous.
- Sarcoidosis – Infiltrative papules and plaques that can be seen around the nares. The micropapular variant may resemble syringomas.
