Background: Aggressive fibromatosis (syn. desmoid tumor) is a sporadically occurring neoplastic proliferation of fibroblasts originating from musculoaponeurotic planes, forming invasively growing masses without the capability to metastasize. The choice of treatment remains surgical resection with or without radiotherapy, and is characterized by high recurrence rates. Better understanding of the aetiology of aggressive fibromatosis is needed to be able to develop new treatment strategies to cope with the high recurrence rates.
Methods: Relevant studies were identified through a search of the electronic databases PubMed/ Medline. The following search terms were used: 'aggressive fibromatosis', 'desmoid tumor', 'adenomatous polyposis coli', 'APC', 'beta-catenin', 'Wnt', 'Wingless' and 'Wnt/Wingless'. Studies were selected for review on the basis of abstract reading. A hand search was performed by checking reference lists in selected articles.
Results: The neoplastic nature of aggressive fibromatosis and the role of the adenomatous polyposis coli (APC) and beta-catenin signaling cascade in driving the onset and progression of this disease are discussed.
Conclusion: Mutations in either the APC or beta-catenin genes are likely to be a major driving force in the formation of these desmoid tumors. More research is needed to develop new treatment strategies.

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.

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.

Article Synopsis
- Desmoid tumours are rare benign growths that can aggressively invade surrounding tissues, especially near nerves and blood vessels, making them difficult to treat.
- Their exact cause is unknown, but they are more common in females and may be linked to factors like trauma, surgery, or inflammation, suggesting possible genetic or hormonal influences.
- A case study highlights a 34-year-old woman who developed a desmoid tumour in her neck after neck surgery; despite surgical removal, the tumour recurred, necessitating a second operation for complete treatment.

Background: Desmoid-type fibromatosis of the breast is a rare, benign, but locally aggressive tumor that typically affects women. Its presentation in male patients is exceedingly rare, and even more so following a cosmetic procedure such as liposuction. This case report describes a unique presentation of breast fibromatosis in a male patient, who developed the condition after undergoing liposuction for cosmetic purposes to define the pectoral area.
