Results: The commonest bronchogenic carcinoma was squamous cell carcinoma (42%) followed by adenocarcinoma (20%), small cell carcinoma (4%), adenosqumaous cell carcinoma (4%) and large cell carcinoma (2%). Conclusion: The histopathological examination of bronchogenic carcinoma cases is helpful for the management of the patients.
