SEBACEOUS ADENOMA: Review of the Literature and Report of a Case

Whether or not true adenoma of sebaceous glands exists is still an unsettled question. Because a tumor which was recently studied at the Massachusetts General Hospital is believed to provide evidence in favor of the existence of sebaceous adenoma, it is believed appropriate to report the histologic appearance of this tumor together with a review of the pertinent literature.

REVIEW OF LITERATURE  An adenoma may be defined as an organoid tumor consisting of circumscribed proliferations of incompletely differentiated glandular structures. Lesions in which the glandular structures are mature or nearly mature are, therefore, not adenomas. On this basis adenoma sebaceum (Pringle) and senile sebaceous adenoma are generally no longer considered adenomas.Authors of recent articles are almost unanimously in agreement that adenoma sebaceum (Pringle) represents an organic nevus.¹ Only Gilman² classifies it as adenoma, because of the development of the lesions later in life and the disorderly "adenomatous"
