Spontaneous Regression of an Intraabdominal Desmoid Tumor in a Patient with Total Gastrectomy

Desmoid tumor is rare neoplasm characterized by clonal proliferation of myofibroblasts that do not metastasise, but often exhibit an infiltrative pattern and functional impairment. The etiology of this tumor is unknown, but hormonal, genetic, and physical factors play a role in its development and growth. The clinical behavior and natural history of desmoid tumors remains unpredictable and enigmatic. However, spontaneous regression of desmoid tumors is rare. Here we report spontaneous regression of an intraabdominal desmoid tumor in a patient who underwent total gastrectomy. (Korean J Med 2011;81:487-491)
