Hu. Baer et al., SUBCUTANEOUS PERIUMBILICAL METASTASIS OF A GALLBLADDER CARCINOMA AFTER LAPAROSCOPIC CHOLECYSTECTOMY, Surgical laparoscopy & endoscopy, 5(1), 1995, pp. 59-63
The frequency of gallbladder carcinoma is 1.2 to 7.4% of all cholecyst
ectomy specimens. In open cholecystectomy for gallstone disease, undet
ected gallbladder carcinoma is found postoperatively in the histologic
al examination in 0.3%. Tumor cells of these clinically inapparent gal
lbladder carcinomas can be implanted at the trocar sites during laparo
scopic cholecystectomies. We report a case with subcutaneous tumor see
ding at the navel trocar insertion site in a 65-year-old woman.
