Delayed presentation of port-site metastasis from an unknown gastrointestinal malignancy following laparoscopic cholecystectomy.

Port-site metastasis (PSM) is often encountered during laparoscopic surgery in patients with malignancy. We report a 45-year-old woman who presented with a single PSM from papillary adenocarcinoma after undergoing laparoscopic cholecystectomy for calculus cholecystitis. Post cholecystectomy, a diagnosis of chronic cholecystitis was confirmed on histopathology. The patient presented with a mass at the site of epigastric port 28 months after surgery. PSM was suspected on clinical examination, which was supported by findings on computed tomography and further confirmed by fine-needle aspiration cytology of the lump. The patient underwent surgical clearance of the mass, and histopathological examination proved the lesion to be papillary adenocarcinoma. The site of the primary tumour was not detected even after thorough examination. Based on the histopathology report following local surgical clearance, the patient was started on chemotherapy. This case is unusual because of the long delay prior to the presentation of PSM and the unknown primary malignancy.
