Unexpected gallbladder cancer with cutaneous seeding after laparoscopic cholecystectomy.

We describe a case of gallbladder carcinoma involving full thickness of the gallbladder wall after laparoscopic cholecystectomy for cholecystitis. Laparotomy for removal of the gallbladder bed and excision of the umbilical cannula site revealed focal residual tumor in the liver bed and microscopic tumor implant in the cannula site. Postoperatively, the patient had radiotherapy of the tumor bed and umbilical scar. Eleven months later, the patient was alive without any evidence of relapse. Excision of the gallbladder bed and laparoscopic scar with or without complementary radiotherapy may be indicated for management of cases in which transmural extension of the unexpected gallbladder carcinoma occurs after laparoscopic cholecystectomy.
