Multiple Benign Cystic Epithelioma

Synonym: Epithelioma adenoides cysticum (Brook)

Multiple Benign Cystic Epithelioma is a rare hereditary disorder. Onset is at puberty. Lesions are mostly confined to the central part of the face and temples, distributed usually bilaterally symmetrically.

Signs and symptoms of Multiple Benign Cystic Epithelioma

Typically, lesions consist of asymptomatic, discrete pin-head to pea-sized, pearly, pale-pinkish, solid, round or oval papulo-nodules embedded in the skin; they are, only slightly raised above the surface. They develop for a few years and then become stationary. Only rarely do they ulcerate or become malignant.

Histology consists of proliferation of mature basal cells from outer walls of hair follicles forming strands and cysts. No mitotic figures are seen.

Treatment of Multiple Benign Cystic Epithelioma

Treatment is surgical. Dermabrasion, liquid N2 or CO2 laser may benefit in some cases.
