Desmoid fibromatosis of the esophagogastric junction.

Summary

We present the case of an 82-year-old male with constitutional syndrome. A computed tomography was performed, which identified a 69 x 52mm mass in the oesophago-gastric union. A computed tomography guided biopsy was performed and the histological analysis identified a fusocellular tumor compatible with desmoid fibromatosis. Treatment was started with indomethacin. However, a control computed tomography 3 months later showed that the mass had grown. Thus, indomethacin treatment was stopped and tamoxifen treatment was started. The patient has had an excellent performance status since symptom presentation. In conclusion, desmoid tumors are rare and most are sporadic. However, they may also be associated with familial adenomatous polyposis syndrome. It must be emphasized that our patient did not have any risk factors and the anatomical location in the oesophago-gastric union is not a common location. Desmoid fibromatosis supposes a clinical challenge for diagnosis and treatment and thus, management should be individualized.
