Primary carcinomas of the Waldeyer's ring area are typically nonkeratinizing squamous cell carcinomas (SCC). Their cervical lymph node metastases are not uncommonly cystic and filled with necrotic tumor cells. Some cysts, however, contain clear fluid. During the investigation of SCC producing "fluid-filled" cystic metastases, we evaluated hematoxylin and eosin (H&E) sections of 90 primary SCC for their site of origin. We analyzed the cytokeratin (CK) profile of primary and metastatic carcinoma… CONTINUE READING
