[Cylindrical epithelioma of nasal cavities and accessory sinuses. Anatomoclinical study of 26 cases].

Report of a series of 26 cases of cylindrical epithelioma of the nasal cavities and accessory nasal sinuses. These neoplasms constitute a remarkably homogenous group the main characteristics of which are following: -- uniform histological pattern, similar to that of the epitheliomas of the colon, -- ethmoidal location in almost all cases, -- preferential occurrence in wood-workers, for instance in the Bas-Rhin. The prognosis depends on the extension of the epithelioma verified in 16 patients during the intervention. Recurrences caused death in 13 patients of this series. Ganglionic or distant metastases are rare. Six patients, i.e. 24 p. 100 had a favourable evolution of at least 3 years. Discussion about the therapeutics of the primary tumor and of its recurrences.
