Desmoid tumour is an uncommon, locally invasive non-metastasizing neoplastic lesion. The pathogenesis of this tumour is unclear and its treatment is controversial. In this paper, the authors report a new case of chest wall desmoid tumour in a 67-year-old man previously operated by sternotomy for a triple aortocoronary bypass. To the best of our knowledge only two cases of thoracic desmoid tumours following aortocoronary bypass have been reported in literature. The correlation between the site of the surgical approach and the tumour, and the time interval between surgery and presentation, supports the hypothesis of a causal role of surgical trauma in the occurrence of this tumour. The Authors discuss the pathogenesis of this tumour with review of the current literature.

Diagnostic utility of LEF1 and β-catenin in WNT pathway tumors with CTNNB1 mutation.
World J Surg Oncol

Department of Pathology, Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, 1665 Kongjiang Road, Yangpu District, Shanghai, 200092, China.
Objective: This study aimed to compare the expression of lymphoid enhancer factor 1 (LEF1) and β-catenin in basal cell adenoma (BA), desmoid-type fibromatosis (DF), and pancreatic solid pseudopapillary neoplasm (SPN) to evaluate their diagnostic utility in tumors associated with the WNT/β-catenin signaling pathway harboring the mutation of CTNNB1 gene 3 exon.
Methods: Eighty tumor patients, including 26 BAs, 30 DFs, and 24 SPNs, were analyzed. Immunohistochemical staining was identified positive (nuclear staining of LEF1 and β-catenin in > 50% of tumor cells).

Introduction And Importance: Desmoid tumours typically arise in the abdomen and extremities. They are rare, originating from mesenchymal cells, with intra-abdominal desmoid tumours (DT) being even less common. While non-malignant and non-metastatic, they can be locally invasive, often necessitating surgical intervention for complete resection.

Desmoid-type fibromatosis (DTF) is a locally invasive tumor composed of myofibroblast-like cells and collagen; it does not metastasize but can cause significant local morbidity. Most sporadic cases are associated with mutations in the CTNNB1 gene, which encodes beta-catenin. Various treatments have been used with differing efficacy and toxicity profiles.
