Bronchioloalveolar carcinoma presenting with obstructive jaundice: A case report.

ABSTRACT

An unusual case of bronchioloalveolar carcinoma of the lung presented with chronic cough and obstructive jaundice in an adult Thai male, who subsequently died after having undergone palliative treatment with percutaneous transhepatic biliary drainage (PTBD). Autopsy finding included typical bronchioloalveolar carcinoma diffusely distributed in both lungs and its metastatic tumors at paratracheal nodes, both adrenal glands, spleen, liver and soft tissue around common bile duct that caused obstruction of biliary tract mimicking hepato-biliary cancer, clinically. In addition to histopathologic evaluation, the ultrastructural finding of dense bodies reminiscent of lamella bodies, and the identical DNA index of near diploid aneuploid cell cycle of the tumors in the lung and liver, confirmed the bronchioloalveolar carcinoma of the lung as the primary tumor that had a widespread metastasis.
