[Non-Hodgkin lymphoma of the infratemporalis fossa: a case report].

Extranodal non-Hodgkin lymphoma of the head and neck is usually seen in the Waldeyer's ring. Localizations in the infratemporalis fossa are rare and to date, only seven cases have been reported. The clinical and radiographic features of non-Hodgkin lymphoma is non-specific. Positive diagnosis requires a pathologic examination, generally guided by immunohistochemistry results. We report a case and discuss the epidemiological, diagnostic, therapeutic and prognostic features of these tumors.
