Concomitant adenosquamous carcinoma of the common bile duct and early adenocarcinoma of the gall-bladder.

We report a 59 year old male with obstructive jaundice and a clinical diagnosis of carcinoma of the midportion of the common bile duct. Examination of the surgical specimen revealed a small tumour in the neck of the gall-bladder. Histologic examination revealed the tumour in the common bile duct was an adenosquamous carcinoma whereas that in the gall-bladder was an early papillary adenocarcinoma. Thus, this is a rare case of the simultaneous development of adenosquamous carcinoma and early papillary adenocarcinoma in the biliary tree.
