Title: A Case of Cervical Lymph Node Metastasis from a p16-Positive Unknown Primary Cancer Diagnosed by Needle Biopsy
Abstract: The American Joint Cancer Commission (AJCC) and Union for International Cancer Control (UICC) 8th Edition modified their TNM Staging Manual by introducing a staging rule for carcinoma of unknown primary in the head and neck (CUP). Histopathological examination of the lymph node is necessary for the diagnosis of CUP to determine viral involvement in the case of nasopharyngeal or oropharyngeal cancer. However, an open biopsy should be avoided to prevent tumor cell dissemination. Herein, we reported a case of neck mass which was diagnosed as a CUP, potentially from oropharyngeal cancer, by core needle biopsy (CNB).
