[Laryngeal Atypical Carcinoid Combined with Squamous Cell Carcinoma: A Case Report].

The primary laryngeal atypical carcinoid is relatively rare, and the tumor combined with other histologic types including squamous cell carcinoma is extremely rare. We experienced a case which was complicated with atypical carcinoid and squamous cell carcinoma. A 79 years old man complaining of sputum was admitted to Hiroshima City Hospital. A tumor was seen in over the right glottis and the right vocal fold was fixed. Squamous cell carcinoma was diagnosed based on a biopsy harvested under laryngoscopy. Imaging studies (CT, MRI) were done. The primary tumor was in the right aryepiglottic fold, and one swollen lymph node was found in level 2 (right side). Based on the findings, the stage was T3N1M0. We performed a total laryngectomy and right neck dissection. Atypical carcinoid and squamous cell carcinoma were detected in the same tumor. There were two lymph node metastases, both of which were atypical carcinoid metastases. Postoperative irradiation was provided. It is now 4 years since the operation, but the patient lives without relapse and metastasis of this disease.
