LUNG - Secondary carcinoma (primary squamous lung)

History
This man was admitted to hospital in November 1975 with increasing shortness of breath, decreased exercise tolerance, pleuritic pain and right-sided weakness. Previously, he had had recurrent attacks of bronchitis, and he had been a heavy smoker for 40 years. Examination showed spider naevi, a right pleural effusion, enlarged supra-clavicular lymph nodes, an enlarged liver, and left hemiplegia. Death occurred approximately 1 week after admission. At autopsy, a poorly-differentiated squamous cell carcinoma of the right upper lobe bronchus was demonstrated, with multiple metastases in the lungs, local lymph nodes and kidney.
