title: An unusual case of port site metastasis after laparoscopic cholecystectomy in a renal transplant patient: a case report.
abstract: Port site metastasis after laparoscopy is a rarely seen intraabdominal malignancy independent of tumor stage. We present an unusual case of port site adenocarcinoma metastasis from unknown origin following laparoscopic cholecystectomy. A 52-year-old woman with a previous renal transplant underwent a laparoscopic cholecystectomy for symptomatic cholelithiasis. Six months later, she was admitted to the hospital with a complaint of a mass at the four trocar sites. A biopsy from the port sites led to the diagnosis of adenocarcinoma metastasis. Port site metastasis after laparoscopic cholecystectomy is seen especially after gallbladder cancer, and less frequently after intraabdominal malignancy independent of tumor stage. Our patient illustrated that port site metastasis probably spread from an undetected cancer site of an early stage intraabdominal tumor. Immunosuppression may have increased the likelihood of tumor seeding at the port sites.
