We reviewed cytological and pathohistological records of 150 patients obtained during the esophagoscopy within a three year period (January 1st 1997 till December 31st 1999). Reports of endoscopic brushings and biopsies imprint cytology of esophageal lesions were compared to pathohistological reports. Cytological diagnoses were divided into 4 categories: negative for carcinoma, presence of atypical cells, suspicious for carcinoma and positive for carcinoma. Moreover, the group positive for carcinoma was further divided according to its carcinoma type (planocellular carcinoma or adenocarcinoma). Carcinoma  was found in 96 cases and confirmed by both cytology and pathohistology in 87 per cent of the cases. In 9 per cent of the cases pathohistology failed to determined carcinoma, but it was diagnosed by cytology and confirmed by other diagnostical methods. On the other hand, histopathology revealed carcinoma in 4 per cent of our case material where cytology failed to determine it. Type of carcinoma was determined by cytological examination in 67 per cent of the cases, (of which in 97 per cent of the cytologically determined tumor type was confirmed by histopathology). Based on this, it could be concluded that combined use of both histological and cytological examinations
would give the highest probability in the determination of esophageal carcinoma.
