Two cases of carcinoma of the larynx, which were found in teenagers, were reported: a fourteen year-old girl supralottic type, squamous cell carcinoma, Stage III (T2N1M0) and a seventeen year-old girl (glottic Type, carcinoma in situ, Stage I (T1N0)). The former was treated with irradiation followed by surgery, and in the latter, radiation only. The vocal cords were saved in both cases. No recurrance of tumor is seen for one and half year in the former case and six months in the latter after treatment. The followings are discussed: how to combine radiation therapy and surgical treatment, concerning skin incisions of partial resection, regional application of anti-cancerous drugs, and the functions of speech and swallowing after surgery.
