During the last 2 decades, major progress has been made and it has become obvious that human papilloma virus (HPV) infection plays a major role. Mostly the morphological aspects will lead the pathologist to classify the carcinoma into HPV-related and nonrelated carcinoma. Although polymerase chain reaction is the gold standard for HPV detection, immunohistochemistry is also useful. These tumors have to be staged according to the pTNM system; nevertheless, two different systems exist, and the pathologist should tell whether he/she uses the European (Union for International Cancer Control) or the American (American Joint Committee on Cancer) staging system.
