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. 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.
