A Case of Primary Malignant Lymphoma of The Tongue

We experienced a very rare case of primary malignant lymphoma of the tongue. The patient was an 83-year-old Japanese woman. Her chief complaint was swelling of the tongue for half a year. Fine needle biopsy from her tongue mass was performed at a previous hospital and showed no malignant cells. This hospital introduced her to our hospital for the purpose of scrutiny.At the first visit to our Department of Otorhinolaryngology, the tongue surface showed no erosion or ulcer, but hard tumors were palpable in the subepithelium of the central region of the tongue. Open biopsy of this tumor was performed and was diagnosed as T-cell lymphoma. PET-CT revealed no metastasis findings and bone marrow biopsy showed abnormal findings. This lymphoma was classified as Stage I (Ann Arbor classification). We consulted the Department of Hematology and she received chemotherapy by hematologists. Two years have passed since the start of chemotherapy. At present, this lymphoma shows no growth in the tongue or whole body
