Pathology of squamous carcinomas of the head and neck.

Recent publications dealing with the pathology of squamous carcinomas of the head and neck have been critically reviewed with particular reference to potential prognostic factors and improved methods for identifying nodal metastases. The topics covered include cytophotometry and proliferative patterns, molecular biology (EGFR and p53 genes), cell adhesion molecules (E cadherin), and combined radiologic and pathologic approaches to detect small volume metastases in cervical lymph nodes.
