[Carcinoid of the larynx]

Laryngeal carcinoid with metastases to cervical lymph nodes was observed in a patient of 62. The diagnosis was confirmed by electron-microscopic study. The patient was followed up for 9 mos without any evidence of recurrence and metastases after laryngectomy and fascial envelope excision of cervical fat. The morphologic picture of laryngeal carcinoid is characterized by the presence of the alveolar, trabecular and teniform structures consisting of monomorphic and moderately polymorphic cells. Tubular and rosette-like structures occur. The overlying epithelium is intact. The necrotic foci, as a rule, are absent. Grimelius reaction is positive, argentaffinnic granularity isn't revealed. Electron-microscopic study demonstrates endocrine-type granules. The need for recognition of laryngeal carcinoid is explained by the fact that this tumour form has a more favourable course and prognosis in comparison to cancer.
