RESUMO
Desmoid tumours are rare tumours originating from fibroblasts, and are characterised by local infiltration and no metastasis. When complete resection is possible, surgical resection is considered a first-line treatment. In the case of large desmoid tumours, it is mainly performed by laparotomy, not laparoscopy. We report a case of a 43-year-old female patient presenting with a hypodense mass of approximately 5 cm in the posterior wall of the gastric antrum on computed tomography. There was no history of familial adenomatous polyposis, trauma or abdominal surgery. The patient underwent laparoscopic gastric wedge resection and spleen-preserving distal pancreatectomy without peri-operative complications. Pathological analysis revealed a desmoid tumour, which originated from the stomach and invaded the pancreas. Despite the large size and the locally infiltrative characteristics of these tumours, laparoscopic surgery can be an optimal treatment option due to its advantages.
