A 60‐year‐old white woman with laryngeal oat cell carcinoma is described. She was a heavy smoker who had been treated seven years earlier with 5,000 rads for a well differentiated squamous cell carcinoma metastatic to a left submandibular lymph node. She presented this time with a two month history of hoarseness and tumor of the supraglottic larynx was found. There was clinical and chemical evidence of an ectopic ACTH syndrome. The histology and fine structure of the tumor were typical of oat cell carcinoma. Immuno‐reactive ACTH, GRP, NSE, Beta‐endorphin, calcitonin, and keratin were found in the cytoplasm of the tumor cells by indirect immunoperoxidase techniques. We could find no previously reported case of laryngeal oat cell carcinoma with ectopic ACTH syndrome or cytoplasmic localization of polypetides. ACTA PATHOL. JPN. 35: 915–923, 1985.
