Carcinoma of the cystic duct presenting as obstructive jaundice

Cystic duct carcinoma is a rare disease. We present here a case of 33-year-old female patient who presented with obstructive jaundice. An abdominal ultrasound and computed tomography scan showed dilatation of intrahepatic biliary radicals with abrupt narrowing of the common bile duct and markedly distended gall bladder suggestive of obstructive pathology. Following an exploratory laparotomy, a markedly distended gall bladder, cystic duct specimen and infrapyloric lymph nodes were sent for histopathological examination. Histopathological examination revealed a well-differentiated adenocarcinoma of the cystic duct with no lymph node metastasis.
