The field of head and neck pathology was just developing 50 years ago but has certainly come a long way in a relatively short time. Thousands of developments in diagnostic criteria, tumor classification, malignancy staging, immunohistochemistry application, and molecular testing have been made during this time, with an exponential increase in literature on the topics over the past few decades: There were 3506 articles published on head and neck topics in the decade between 1969 and 1978 (PubMed source), with a staggering 89266 manuscripts published in the most recent decade. It is daunting and impossible to narrow the more than 162000 publications in this field and suggest only a few topics of significance. However, the breakthrough in this anatomic discipline has been achieved in 3 major sites: oropharyngeal carcinoma, salivary gland neoplasms, and sinonasal tract tumors. This review will highlight selected topics in these anatomic sites in which the most profound changes in diagnosis have occurred, focusing on the information that helps to guide daily routine practice of surgical pathology.
Keywords: Head and neck; Immunohistochemistry; Molecular; Oropharyngeal; Paranasal sinus neoplasms; Pathology; Salivary gland neoplasms.
