Sebaceous adenoma is a cutaneous condition characterized by a slow-growing tumour usually presenting as a pink, flesh-coloured, or yellow papule or nodule.

Sebaceous adenomas, in isolation, are not significant; however, they may be associated with Muir-Torre syndrome, a genetic condition that predisposes individuals to cancer.[3] Thus, identification of a sebaceous adenoma may be a life saver.

It is associated with tuberous sclerosis complex. The term adenoma sebaceum is a misnomer.
