Oxyphilic proliferations of the respiratory tract and paranasal sinuses.

Neoplasms of the upper respiratory comprised primarily of eosinophilic cells are, in general, rare, and they include a diverse group of lesions. Low-grade oncocytic neuroendocrine neoplasms (so-called oncocytic carcinoids) can be encountered in several locations throughout the respiratory tract. The oncocytoma and related entities, lesions that presumably arise from minor gland tissue, can likewise be seen from the nasal cavity to the lung; differences in clinical significance may relate to the location of such lesions, and are discussed herein. Granular cell tumor is another entity that can involve both the upper respiratory tract and lungs, and specific features of this lesion in different anatomic sites are highlighted. The oncocytic variant of Schneiderian papilloma is an important nasal lesion to recognize, because of important therapeutic and prognostic implications of that diagnosis. Finally, unique oncocytic variants of glomus tumor and pulmonary alveolar adenoma are discussed, as well as eosinophilic varieties of pulmonary carcinomas and mesotheliomas.

[The program for early diagnosis of the upper respiratory tract and digestive system neoplasms offered to alcoholics in the region of Friuli-Venice Giulia].

The present study deals with data from an on-going collaborative programme of early diagnosis for upper aero-digestive tract tumors established since 1990 by three ENT Departments of the Friuli-Venezia Giulia Region, Northeastern Italy. The aim of the study was firstly to evaluate the socio-economic characteristics and clinical features of alcoholics in treatment who were offered a free ENT check-up, and secondly to test the feasibility of this type of referral of high-risk patients from non-medical associations to the ENT specialist. A total of 683 patients, of which 151 (78%) were males and 151 (22%) were females, underwent ENT examination. About 25% of the patients were symptomatic, the most frequent symptom being dysphonia (50%) followed by cough (19%), while dyspnoea, dysphagia and pain were present in about 5% of the patients. Other than nearly 50% negative findings, ENT examination revealed a high percentage of inflammatory lesions (30%) of the upper aero-digestive tract. In 37 patients (6%) a precancerous lesion was found and in four cases an histologically confirmed tumor was diagnosed. Although the present study cannot be considered a complete screening, it did clearly evaluate the amount of response given by this high-risk population of alcoholics in treatment to the offer of an ENT examination and gives encouraging results concerning the feasibility of early diagnosis programmes for upper aero-digestive tract tumors which do not follow the normal routine of a sanitary referral by a general practitioner.
