Abstract
Malignant lymphomas arising in the head and neck area include nasal NK-cell lymphoma, paranasal diffuse large B-cell lymphoma (DLBCL), Waldeyer ring DLBCL, and DLBCL and MALT (mucosa-associated lymphoid tissue) lymphoma of the salivary glands and thyroid. In the cervical lymph nodes, various types of lymphomas are found, including DLBCL, follicular lymphoma and Hodgkin lymphoma. Here, I will describe the treatment of early stage and advanced stage lymphomas, with particular emphasis on that of nasal NK- cell lymphoma.
