This study examined immunohistochemical findings of sebaceous carcinoma and sebaceoma. An immunohistochemical study using 13 anti-cytokeratin (CK) antibodies (anti-CK1, 5-8, 10 and 14-20) and 35 cases of sebaceous carcinoma (16 cases on ocular and 19 cases on extraocular regions) and 10 cases of sebaceoma (no cases arose on the eyelids) was performed. Overall, those in ocular lesions were almost the same as those for extraocular lesions in sebaceous carcinoma other than CK8. The findings in sebaceous carcinoma were almost equal to those of sebaceoma. Over 75% of cases with sebaceous carcinoma were positive with anti-CK5 and anti-CK14 antibodies and negative with anti-CK1, CK10, CK15, CK17, CK18 and CK20 antibodies. Most cases (50-75%) of those were positive with CK7 and negative with CK6, CK16, CK19 and CK8. The sensitivity and specificity of immunohistochemical detection of sebaceous carcinoma using the panel of anti-cytokeratin antibodies were lower than those of other antibodies. Immunohistochemical detection of cytokeratins in diagnosing sebaceous carcinoma should be considered to be ancillary to conventional microscopic findings and those of other antibodies.

Diseases of the sebaceous glands such as sebaceous hyperplasia and sebaceous cell carcinoma (SEBACEOUS GLAND NEOPLASMS).
Small, sacculated organs found within the DERMIS. Each gland has a single duct that emerges from a cluster of oval alveoli. Each alveolus consists of a transparent BASEMENT MEMBRANE enclosing epithelial cells. The ducts from most sebaceous glands open into a HAIR FOLLICLE, but some open on the general surface of the SKIN. Sebaceous glands secrete SEBUM.
A malignant tumor of the skin appendages, which include the hair, nails, sebaceous glands, sweat glands, and the mammary glands. (From Dorland, 27th ed)
A transplantable carcinoma of the rat that originally appeared spontaneously in the mammary gland of a pregnant albino rat, and which now resembles a carcinoma in young transplants and a sarcoma in older transplants. (Stedman, 25th ed)
An adenocarcinoma characterized by the presence of cells resembling the glandular cells of the ENDOMETRIUM. It is a common histological type of ovarian CARCINOMA and ENDOMETRIAL CARCINOMA. There is a high frequency of co-occurrence of this form of adenocarcinoma in both tissues.
