Desmoid tumors, also known as aggressive fibromatoses, are clinically rare soft-tissue tumors that arise from such connective tissues as the musculoaponeurotic structures. The majority of the reported intra-abdominal desmoid tumors occur in the small intestinal mesentery and peritoneum, whereas stomach desmoid tumors are extremely rare. The present study reports a case of stomach desmoid tumor and reviews the related available literature. The diagnosis of the stomach desmoid tumors can be made with routine pathological and immunohistochemical examinations. Compared with desmoid tumors at other sites, the currently preferred treatment of the stomach desmoid tumors with negative margins is radical resection of tumors. All the follow-ups of patients with the stomach desmoid tumors show no obvious recurrence, suggesting that the prognosis of the stomach desmoid tumors is good.

Gardner syndrome is characterized by multiple intestinal polyps and extraintestinal lesions. We describe FDG PET/CT findings of the extraintestinal lesions in a patient with Gardner syndrome. FDG PET/CT showed 2 hypermetabolic desmoid tumors in the abdominal wall, sclerotic areas with multifocal activity in the maxilla and mandible, multiple osteomas in the bilateral parietal, left frontal, sphenoid and ethmoid bones, an impacted tooth in the right maxilla, and bone islands in the T2 and T5 vertebral bodies.

Background: Familial adenomatous polyposis is a cancer-predisposing syndrome caused by germline pathogenic variants of the adenomatous polyposis coli gene, leading to numerous colorectal polyps and a high risk of colorectal cancer. Desmoid tumours have become significant in the management of familial adenomatous polyposis after a colectomy, yet the exact incidence remains undetermined due to a lack of dedicated surveillance.
Methods: This retrospective study accessed data from the prospectively maintained Hereditary Digestive Tumours Registry from 2000 to 2023.

Several extra-colonic manifestations, including duodenal polyposis and desmoid tumors, are well-described manifestations in familial adenomatous polyposis (FAP). More recently, an increase in gastric cancer diagnoses has been observed in FAP. This case series presents nine patients with FAP who were diagnosed with gastric cancer at our FAP expertise center, of whom eight were diagnosed between 2017 and 2023, while before 2017 the only diagnosis of gastric cancer was in 2001.
