We encountered a rare case of malignant lymphoma from the postcricoid area of the hypopharynx in a 69-year-old female. The patient presented with a six week history of throat pain and on examination a smooth and well-defined mass was found in the right postcricoid area of the hypopharynx. The mass was about 2cm in size, pale pink and partially red. Enhanced CT and MRI (Gd) revealed partial enhancement and a slightly irregular, homogenous mass 2cm in size in the right postcricoid area. Ga<sup>67</sup> scintigraphy revealed uptake only by the hypopharyngeal tumor lesion. The mass was biopsied with laryngofiberscopy and the pathological diagnosis was non-Hodgkin's lymphoma, diffuse large B cell type. After the I E Ann Arbor clinical stage was established, radiation therapy alone was begun. There has been no evidence of recurrence for 1 year 8 months after primary therapy. Radiation therapy alone was selected because the tumor was regional type stage IE and was small and could be effectively treated with primary therapy. However, since it was classified as intermediate grade in Working Formulation, careful follow up is necessary.
