Patients may be concerned for cosmetic reasons or worry about possible malignancy. Lesions usually are described as asymptomatic, soft, discreet, and yellow-colored, with a smooth to slightly verrucous surface. Patients may complain of one or multiple lesions at various locations on the face. Lesions may become red, irritated, and bleed after scratching, shaving, or other trauma. A change seems to occur in the rate sebocytes migrate from their points of differentiation into the sebaceous unit.
Gland is enlarged with a widened sebaceous duct and an increased number of basal cells.
These lesions reveal individual, discreet, enlarged glands. Within each gland, mature sebaceous lobules surround and connect to a central, widened sebaceous duct. Treatments are mostly mechanical. Lesions tend to recur unless the entire unit is destroyed or excised. Risk of permanent scarring must be considered when treating benign lesions.
