[Correlation between the clinical and pathohistologic diagnosis in "small biopsies" of the lung].
BACKGROUND
During the last 20 years routine application of various methods of multiple "small biopsies" of the lungs such as forceps, transbronchial, trucut percutaneous and so on, has significantly increased the efficacy of diagnostics of bronchopulmonary and pleural diseases. Tissue samples, not bigger than 3-4 mm, in which diagnostic pathological changes are expected on the basis of previous clinical, radiological and bronchoscopic examinations, can be the basis for making a definite therapeutical decision only if a skillful surgeon has performed the biopsy by correct instruments and from the right place and sent it for histological analysis with other important clinical information. This study is a comment on quality, significance and possibilities of improving clinical-pathological cooperation in this field of clinical pathology.


METHODS
By correlation of clinical and histological diagnoses we analyzed the diagnostic efficiency of microscopic examinations of "small biopsies" of the respiratory tract in 319 patients (175 bronchial forceps biopsies, 31 transbronchial biopsies, 22 percutaneous needle pleural biopsies and 91 combined forceps and transbronchial biopsies) in whom biopsies were performed during 1996 in the Specialized Hospital for Lung Diseases Brezovik.


RESULTS
Overall concordance between the clinical and histopathological diagnosis was 82.2%. In 99 cases (73.3%) out of 135 clinically "obvious" neoplasms, the histopathological examination confirmed existence of malignant tumor: squamous cell carcinoma in 80%, small cell carcinoma in 9.6% and adenocarcinoma in 5.6% of patients. In other patients it was not possible to perform a more precise classification. Endoscopic specimens of 29 patients (9.1%) were not representative.


CONCLUSIONS
The level of diagnostic efficiency (73.3%) of definitive histopathological verification of bronchopulmonary lesions, which have been clinically diagnosed as malignancies, is rather high, but the increase of diagnostic efficiency requires application of more sophisticated histological diagnostic methods (immunohistochemical) and more frequent utilization of bioptic procedures which are more convenient for detection of peripheral pulmonary lesions (transbronchial and percutaneous fine needle aspiration biopsies of the lungs).
