Adenosquamous carcinoma arising in a duplication cyst of the gallbladder
A 52-year-old woman, previously healthy was admitted to another hospital due to right upper quadrant abdominal pain, fever and leukocytosis. An ultrasound demonstrated acute cholecystitis and lesion 8 cm. in diameter near the gallbladder. An abdominal CT scan showed the lesion in close proximity to the gallbladder, with fat infiltration. A percutaneous drainage of the lesion under CT guidance yielded a substance which was bloody and purulent in content. The patient improved clinically under antibiotics and was discharged from hospital with a recommendation for elective exploratory laparoscopy.
