title: [A Case of Oropharyngeal Large Cell Neuroendocrine Carcinoma].
abstract: The large cell neuroendocrine carcinoma (LCNEC) of the lung was first reported in detail by Travis et al. in 1991. Extrapulmonary LCNEC rarely occurs, and only 22 cases have been reported in the head and neck mucosal regions. Today LCNEC of the larynx is contained in the moderately differentiated/Grade 2 category. However some authors advocate that LCNEC of the larynx should be separated from this category because of the difference in the clinical manifestations and pathological features. Standard treatment for head and neck mucosal LCNEC (M-LCNEC) has not been confirmed. However we suggested the efficacy of postoperative chemotherapy for M-LCNEC. This report describes a case of an LCNEC of the oropharynx. The patient was a 64-year-old man. We treated him with surgery and chemoradiotherapy. He has been disease-free for 36 months after adjuvant-chemotherapy.
