title: [Value of cytologic diagnosis of pulmonary carcinoid tumors. A morphologico-clinical analysis].
abstract: 14 centrally and 16 peripherally located carcinoid tumors of the lung were included in the study. For the centrally situated carcinoids the cytological interpretation of imprints or smears from the surface of the biopsy specimens turned out to be superior to the histological diagnosis based on the same endoscopic bronchial biopsy. 10 out of 12 cytologically investigated cases were correctly diagnosed. In the remaining 2 cases one was misdiagnosed as a small cell carcinoma and the other one raised suspicion of malignancy (Pap-III-finding), but no definitive diagnosis could be made. By contrast, out of 11 histologically investigated endoscopic biopsies from central carcinoids 5 were misdiagnosed as small cell carcinomas and in one case the material obtained endoscopically was inadequate. Out of the 16 peripheral carcinoid tumors only 5 were diagnosed cytologically: 3 by catheter aspiration and 2 by transthoracic needle biopsy. The characteristic cytologic feature of carcinoid tumors and the cytological differential diagnosis are described in detail.
