Sebaceous hyperplasia appears as 1-to-3-mm yellow umbilicated papules with overlying telangiectasias on the face of middle-aged individuals (Fig. 15.1). They represent a benign proliferation of sebaceous glands. The lesions are sometimes mistaken for basal cell carcinoma.
Large sebaceous hyperplasia on the forehead
Age: most commonly middle age and elderly but can appear in young individuals as well
Race: more common in Caucasians
Precipitating factors: organ transplantation is a rare precipitant
Increased numbers of large, mature sebaceous lobules are clustered around a central duct in the upper dermis. The lobules lie closer than normal to the epidermis.
There are single or multiple 1-to-3-mm yellow umbilicated papules with overlying telangiectasias that appear on the face. The forehead, cheeks, and nose are the most common locations. It can rarely present on the areola.
Most commonly mistaken for basal cell carcinoma.
None is indicated. Biopsy if considering basal cell carcinoma.
Benign, but do not regress or resolve without therapy.
KEY CONSULTATIVE QUESTIONS
Any history of the lesion bleeding.
There is no medical indication to treat sebaceous hyperplasia. Still, some individuals are significantly bothered by its appearance and request removal, particularly in the circumstance of multiple lesions. Treatments include oral, destructive, laser, and photodynamic therapies. Each has its side effects and risk of recurrence.
All patients should be informed before any treatment modality that improvement is variable and in the future new lesions may arise requiring follow-up treatments.
