Pancreatic squamous cell carcinoma metastasizing along the puncture site 7 days after laparoscopic surgery.

Abstract

A 64-year-old man was admitted to the hospital due to "recurrent abdominal pain for 8 months" and had a history of multiple episodes of pancreatitis. CT scan showed an enlarged pancreas with no normal pancreatic tissue . Contrast enhancement scan in the arterial phase displayed moderate enhancement in the solid portion, while the cystic necrosis area showed no enhancement. It was suspected to be pancreatic cancer, and laparoscopic exploration of the pancreas followed by partial pancreatectomy was performed. Finally, it was confirmed as pancreatic squamous cell carcinoma by immunohistochemistry (P63 (+), CK5/6 (+)). Seven days after the operation, F18-FDG PET/CT showed multiple soft tissue density masses in the upper abdominal wall along the laparoscopic trajectory with increased uptake.
