Desmoid tumors are fibroblastic/myofibroblastic neoplasms, which originate from musculo-aponeurotic structures and are classified as deep fibromatoses. Despite their benign histologic appearance and lack of metastatic potential, desmoid tumors may cause aggres?sive local infiltrations and compression of surrounding structures. They are often associated with female gender, familial adenomatous polyposis (FAP) and sporadically may occur at sites of previous trauma, scars or irradiation. Molecular studies have demonstrated that these patients are associated with a bi-allelic APC mutation in the affected tissue. Radical tumor resection with free margins remains the first therapy of choice. In cases with anatomical or technical limitations for a wide excision, radiation therapy represents a proven and effective alternative or supplementary treatment.

Introduction: Desmoid tumors are soft-tissue neoplasms that can have profound impacts on the lives of people living with such diseases. As they are rare tumors, patients often have difficulty finding teams specialized in sarcomas and support networks. In low- and middle-income countries, the challenges are exacerbated due to a need for established networks and medication access.

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.
