Exophytic endobronchial epidermoid carcinoma.

Exophytic endobronchial epidermoïd carcinoma is a rare clinical entity. The authors describe and systematically analyzed 34 cases, collected during 35 years. There was a preponderance of male patients; the mean age at presentation was 58 years. The tumors were nearly always at the T1N0 stage, and their prognosis was not better than that for other Stage I bronchogenic carcinomas. The findings suggest that they are a special subvariety of bronchogenic carcinoma, rather than tumor detected at an early stage.

[Laryngeal lesions after prolonged intubation. Anatomo-pathologic study]. / Lésions laryngées après intubation prolongée. Etude anatomo-pathologique.

Laryngeal lesions produced during prolonged intubation were studied in 11 larynxes from consecutive patients dying during intensive care. A constant finding was ulceration of the vocal process, combined in 7 cases with inter- or pre-arytenoidal subglottic ulcerations. Histology failed to reveal signs of lesions of the cricoarytenoid joint or chondritis of the posterior arch of the cricoid cartilage.

[Simultaneous or successive locations carcinomas of head and neck (author's transl)]. / Cancers multiples, simultanés et successifs, des voies aéro-digestives supérieures.

204 simultaneous or successive locations of carcinoma were observed and analysed in a series of 1992 cases of head and neck carcinomas for 15 years (10.24 p. 100). Simultaneous carcinomas appeared electively in single anatomical area: hypopharynx, oropharynx, endolarynx. Successive carcinoma on the other hand are developed in adjacent anatomical sites. An oesophagal location worsens the prognosis; the related facts and rules are analysed for their frequency. An early detection II counselled and their pathogenesis is discussed.

[Carcinoma of the upper respiratory and digestive tracts. Histopathology and chemotherapy in 300 cases (author's transl)]. / Chimiothérapie et histopathologie des carcinomes des voies aéro-digestives supérieures. A propos de 300 cas.

The pathological review of 300 larynx hypopharynx and pyriform sinus carcinoma was done systematically. The results expressed according to the absence or the type of chemotherapy (Bleomycine alone or O.M.B. association) are analysed. There is no difference for the epithelial proliferation but the collagenous part of stroma was enhanced by therapeutic. The foreign body granulomas are related to the tumor maturation (keratinization).
