Successful outcomes after laparoscopic spleen-preserving pancreatic resection for a desmoid tumor: A case report

INTRODUCTION: Desmoid tumors are slowly growing neoplasms that arise from fibroblasts. These tumors are locally aggressive and have a high rate of recurrence after surgery. Pancreatic desmoid tumors are extremely rare. The indications and outcomes of laparoscopic surgery for pancreatic desmoid tumors have not been fully elucidated. This report therefore aimed to describe a rare case of a pancreatic desmoid tumor in a patient who was successfully treated with laparoscopic spleen-preserving pancreatic resection. PRESENTATION OF CASE: We report a case of a 60-year-old man who presented with back pain. Contrast-enhanced computed tomography scan revealed a circumscribed tumor in the pancreatic tail measuring 3 cm. The patient underwent laparoscopic spleen-preserving distal pancreatectomy. Pathological analysis revealed a desmoid tumor infiltrating the pancreatic parenchyma. There was no evidence of recurrence at 36 months of follow-up. DISCUSSION AND CONCLUSION: Isolated sporadic pancreatic desmoid tumors are extremely rare. Laparoscopic radical resection could be a safe and effective treatment for this benign but locally aggressive tumor. To the best of our knowledge, this is the first study to report a patient with a pancreatic desmoid tumor who was successfully treated with laparoscopic surgery.
