Lymphomas of the head and neck.

Abstract

Lymphomas of the head and neck arise in Waldeyer's ring, the salivary glands, nasal cavity, paranasal sinuses, thyroid gland, and orbit. Though anatomically in close proximity, lymphomas arising in these sites have distinct clinical characteristics. Factors that appear to influence the pattern of disease include concurrent conditions, such as Sjögren's syndrome, and geographic factors, particularly with regard to nasal lymphomas. The treatment and prognosis of patients with head and neck lymphoma depends on the histologic grade of disease and extent of involvement at time of presentation. Most lymphomas are of intermediate-grade histology and early stage at presentation. A thorough understanding of clinical disease patterns and treatment options will allow the optimum management of these patients.
