Atypical laryngeal carcinoid is a rare tumor with a poor prognosis, mostly occurring in the supraglottic larynx. It is a subtype of neuroendocrine carcinoma which should be separated from typical carcinoid and small cell carcinoma. The histogenesis and standardized classification of laryngeal neuroendocrine carcinoma have not been clearly defined. In this report, we present two cases of atypical laryngeal carcinoid, one occurring in a 67 year old male and the other in a 54 year old female. Indirect laryngoscopy revealed a polypoid supraglottic mass, approximately 3 cm in diameter. Microscopically, each case showed a moderate degree of pleomorphism, tumor necrosis and frequent mitoses. The immunohistochemistry revealed a strong positive reaction for chromogranin, neuron specific enolase and cytokeratin. Each patient had distant metastasis, noted within 4 months after resection (liver and stomach), and died postoperatively at 5 and 20 months, respectively. A brief review of the literature concerning the biological behavior, histogenesis and pathology of atypical laryngeal carcinoid was performed.
