A sebaceous adenoma, a type of adenoma, a cutaneous condition characterized by a slow-growing tumor usually presenting as a pink, flesh-coloured, or yellow papule or nodule.[1]:662[2]


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] It is also linked to hereditary nonpolyposis colorectal cancer (Lynch Syndrome).

It is not the same as "adenoma sebaceum" by F. Balzer and P.E. Ménétrier (1885).[4] The term "adenoma sebaceum" is a misnomer for facial angiofibromas associated with tuberous sclerosis complex.[5][lower-alpha 1][lower-alpha 2]

  1. Balzer and Menetrier (1885) described the microscopic appearance of the facial papules as "adenoma sebaceum", thought to be benign tumors of sebaceous glands, although the skin lesions are actually angiofibromas.

  2. Facial angiofibromas were first described in 1885 by Balzer and Menetrier. At this time, they were incorrectly termed adenoma sebaceum. We now know that the sebaceous glands are only passively involved, if at all. Facial angiofibromas are actually hamartomas, defined as benign, tumorous nodules of superfluous tissue.
