Primary carcinoma of the trachea.

Primary carcinoma of the trachea, in its rarity, contrasts with carcinoma of the bronchus, whose increasing frequency has been recognized during the last twenty-five years. Since von Bruns's publication of the statistics available up to 1898, the literature has been reviewed by Krieg (1908), Lombard and Baldenweck (1914), d'Aunoy and Zoeller (1931), and Culp (1938), the last of whom reviewed in detail all cases reported up to June, 1936. In this paper we describe a case of primary tracheal carcinoma closely resembling one of Culp's reported cases, and we review the literature, including new cases from the period June, 1936, to December, 1945.
