N2 - This tutorial focuses on salivary duct carcinoma (SDC), a rare, high grade neoplasm mainly of major salivary glands. The clinical course of these tumors is characterised by extended local disease, early distant metastasis, and poor outcome. The morphology of SDC is reminiscent of breast ductal carcinomas and may occasionally cause diagnostic problems. In spite of mimicry with ductal carcinoma in situ of the breast and an in situ component, that is evident in most tumors by immunohistology with antibodies directed against high molecular weight cytokeratins (Ck), SDC is always an invasive carcinoma. By immunohistology, most tumors show reactivity with antibodies directed against Ck 7, Ck 8/18 and Ck 19 whereas a morphologically indistinguishable subgroup expresses Ck 5/6 in tumor cells in addition to residual basal epithelia. Carcinoembryonic antigen, GCDFP-15 and androgen receptor are other helpful markers in routine diagnosis of SDC. Prostate-specific antigen is detectable in some cases. Abnormal p53 expression seems to indicate an adverse prognosis. Expression of c-erbB2, the over-expression of which is associated with a poor prognosis, may form the basis for a targeted therapeutic approach for selected cases of SDC.
