title: Recurrence of cholangiogenous carcinoma in port-sites two years after laparoscopic removal of noncancerous gallbladder.
abstract: We present a unique case of carcinoma diagnosed in port-site, two years after uncomplicated laparoscopic cholecystectomy for benign cholecystitis. Analysis of morphology and cytokeratin profile (CK19+ and CK20+/-) of resected port-site tumor allows us to establish the diagnosis of tubular carcinoma with probable cholangiogenic origin. The primary carcinoma was not diagnosed in archival gallbladder tissue, despite repeated histological examination. No other primary tumor was identified during follow-up. Patient history and histological/immunohistochemical picture of the recurrent tumor suggested that primary carcinoma was probably located in the gallbladder, but was not detected during initial and repeated histological examinations of postoperative specimen. The patient is still alive, 12 months after the first port-site recurrence and 36 months after initial laparoscopy.
