SC62 Nodal Metastases in Head and Neck Lesions: Where’s the Primary?
Session Credits: 3 CME and 3 SAMs
Faculty: Bruce Wenig, MD, H. Lee Moffitt Cancer Center, Tampa, FL and Juan C. Hernandez-Prera, MD, Moffitt Cancer Center, Tampa, FL
The presence of nodal metastatic tumor or what may appear to be metastatic tumor in the absence of a known primary cancer is a fairly frequent occurrence in head and neck cancers. Often, a diagnosis of nodal metastasis is rather straightforward. However, there are scenarios in which the diagnosis may be challenging and confounding given the absence of a known primary cancer or features simulating nodal metastasis in the presence of a benign lesion. This course will provide a detailed overview of select clinically scenarios in which the pathologist is confronted with metastatic carcinoma (or what may appear to be metastatic carcinoma) in the absence of a known primary carcinoma. In addition, the recent published AJCC staging system for unknown primary tumors of the head and neck will be incorporated into the course discussion. The foundation of the course will be traditional light microscopic pathology, which will be integrated with the clinical information and current knowledge of the immunohistochemical and molecular diagnostic features of a variety of head and neck neoplasms.
