Sebaceous adenoma is a rare but benign tumour of sebaceous cells. Its common presentation is that of a smooth, round, yellow and firm nodule or polyp. It has a predilection for the face - particularly the eyelids - and the scalp. The elderly are more afflicted. It has approximately the same incidence in males and females.

Histologically, the tumour is well-demarcated and consists of irregular lobules within the upper dermis. There are multiple layers of small, basophilic cells at the periphery surrounding larger, vacuolated cells.

Sebaceous adenoma may be one of the features of Muir-Torre Syndrome.

Concern over diagnosis or a sudden increase in the rate of growth may prompt excision biopsy. Incomplete excision may result in recurrence. Sebaceous adenomata have been treated with radiotherapy.
