Two cases of malignant lymphoma of the larynx are presented. Case 1 is a 67-year-old female in clinical stage IIEA. Irradiation of 42 Gy was given to the bilateral neck and supraclavicular area. The patient has been disease-free for nearly 15 years after irradiation. Case 2 is an 86-year-old female in clinical stage IEA. Irradiation of 45.2 Gy was delivered to the larynx. The patient had been disease-free for 7.5 years up to her death from intercurrent disease. Histologically, these tumors belonged to the category of low grade B-cell lymphoma of mucosaassociated lymphoid tissue (MALT-type). Although chemotherapy was administered in these 2 cases, it did not lead to an effective outcome. In conclusion, radiotherapy can be considered as a definitive treatment modality for primary malignant lymphoma of the larynx.
