Abstract

<p>A 44-year-old man was diagnosed with gastric cancer and underwent laparoscopic distal gastrectomy, D2 lymph node dissection, and Billroth-I reconstruction. The histopathological diagnosis was pT2N0M0 Stage IB. At one-year follow-up, CT and PET-CT showed a mass in the #6 lymph node dissection area, which was suspected to be lymph node recurrence. Laparoscopic resection was performed and the mass was diagnosed as a desmoid tumor. Preoperative diagnosis of desmoid tumors is generally difficult. Mechanical stimulation by surgery is one of the mechanisms through which desmoid tumors develop, which makes differential diagnosis from recurrence difficult when such tumors occur after gastrectomy for gastric cancer. In cases with a low risk of recurrence, surgery for diagnosis is useful, and resection of other organs or chemotherapy can be avoided if recurrence can be ruled out. We report this case as an example of desmoid tumor that required differentiation from lymph node recurrence after gastrectomy for gastric cancer.</p>
