Abstract
Purpose: 1-general features of lung tumors in Pulmonary Disease University Hospital.
Objectives:
To determine: Distribution by age and sex,The most common histological type.
Material and methods: retrospective study.
Parameters in the study are: distribution by age and sex, groupings according to histopatologic diagnosis.Statistical processing of the data is done with a simple comparative method.
Results: For this period resulted in 395 bronchial biopsy in a total of 1105 biopsies.Broncoscopic biopsies, occupying 36% of the overall .The distribution of pathologies in bronchial biopsies was this:58% -tumors, 28%-inflammation, 6% inadequate material, 5% dysplasia and 3% normal.In consideration of tumor pathology such detection was observed a characterization:
Squamous cell carcinoma 52.5% (42% well differentiated, 36% moderately differentiated and 22% poorly diferenttiated).
Adenocarcinoma 22.5%, Small cell carcinoma -15%,Large cell carcinoma 6%.
4% other pathologies. Male female ratio was approximately 9:1 with a significant predomination in men.
The mean age of tumor pathology resulted from 50-70 years old.
Conclusion
Bronchial biopsy plays an important role in the diagnosis of malignant pathologies.
But in many cases, histopathological diagnosis is a challenge for pathologist and it is also related to insufficient material.
The greater number of particles in tissue taken,increases diagnostic productivity.
