Primary non-hodgkin lymphoma of the larynx.

A rare case of primary large B-cell non-Hodgkin lymphoma of the larynx is reported. The patient was an 80-year-old female who presented with pharyngeal discomfort and dysphagia. Radiotherapy was instituted with complete remission of the tumor. Nine months afterward, she presented with aspiration pneumonia and dysphagia. Indirect laryngoscopy disclosed laryngeal and esophageal edema, which was probably related to radiotherapy. No signs of tumor recurrence were observed. Three months later, she was entirely asymptomatic. Although cases of aggressive course and poor response to therapy exist, primary large B-cell non-Hodgkin lymphoma of the larynx is generally considered a relatively benign and radiosensitive tumor.
