Introduction:
Many patients with desmoids have an antecedent trauma, particularly surgical intervention for familial adenomatous polyposis. However, cases of mesenteric desmoid after gastrectomy are extremely rare. We present a case of multiple mesenteric desmoids after total gastrectomy for gastric cancer.
Presentation of case:
A 70-year-old man had undergone a total gastrectomy for early stage gastric cancer. He had no other relevant medical history or family history. A year after gastrectomy, a computed tomography showed three mesenteric masses, and we performed careful observation. The 2-year postoperative examination indicated slowly growing masses. There were no other lesions except for the three masses. We decided to perform diagnostic surgery to evaluate the tumors. There were three mesenteric masses (1.5 cm, 4 cm and 1.5 cm in diameter). We performed partial small intestinal resections for each mass. Histological examination showed that the tumors were desmoids. A year after surgery, he was doing well with no evidence of recurrence of the desmoids or the gastric cancer.
Discussion:
Diagnosing intra-abdominal desmoid tumors is often difficult. Especially if a patient has a history of malignancy, it may be extremely difficult to differentiate multiple mesenteric desmoids from a cancer recurrence. In the current case, surgical resection was a useful treatment option as diagnostic therapy.
Conclusions:
Multiple mesenteric desmoids could emerge after gastrectomy for gastric cancer, and surgical resection of the tumors is a useful option as a diagnostic therapy.
