PACHECO-MOLINA, Carlos et al. Gastric fibromatosis: a rare tumor in an infrequent location. Case report. Cir. cir. [online]. 2020, vol.88, suppl.2, pp.75-78.  Epub 08-Fev-2022. ISSN 2444-054X.  https://doi.org/10.24875/ciru.20000393.

Desmoid-type fibromatosis is an extremely rare benign tumor with locally aggressive features. It is predominantly developing in soft tissues due to its origin in muscles and aponeurosis. The diagnosis is established by immunohistochemistry with positivity for vimentin, B-catenin and sometimes for smooth muscle actin. The clinical spectrum of presentation is wide, based on this and resectability the treatment is offered. We present the case of a patient with symptoms of gastric outlet obstruction secondary to a subepithelial lesion in the gastric body with conclusive immunohistochemistry for gastric fibromatosis.
