Extrapulmonary Small Cell Carcinoma of the Hypopharyx :A Case Report
We report a case of extraplumonary small cell carcinoma of the hypopharynx. A 78-year-old man was referred for radiation therapy of a hypopharyngeal tumor. The pathological diagnosis was malignant, but inconclusive. Laryngeal fiberscopy revealed a tumor filling the right pyriform sinus. Palpation and MR imaging showed no lymph node metastasis. Further examination showed no distant metastasis. After admission, we again investigated the pathology of the tumor in detail and diagnosed small cell carcinoma. He received concurrent radiotherapy of a total dose of 54 Gy, and chemotherapy consisting of docetaxel, calboplatin and 5-FU, with a complete remission. He has been free from the disease for three years.
