Unsuspected carcinoma of the gallbladder. A laparoscopic dilemma

Laparoscopic cholecystectomy is the treatment of choice for gallstones. A formal contraindication is gallbladder cancer. However, in a great number of cases, this is a previously unsuspected intraoperative finding, and sometimes its first appearance is in acute cholecystitis. We present the case of 67-year-old woman, which presented an unsuspected carcinoma of the gallbladder that developed abdominal wall implants at the umbilical and left hypocondrium site. The success of LC favors the observation of cases similar to that described in this article. Surgeons who operate using laparoscopic techniques should bear this possibility in mind and practice an extemporaneous biopsy at the slightest suspicion of malignancy, and, if it is confirmed, the operation should be continued as an open one.
