The overlying skin is usually unaffected. L Intra-abdominal and extra-abdominal desmoid tumors o Intra-abdominal desmoid tumors remain asymptomatic until their growth and infiltration cause visceral compression. Symptoms of intestinal, vascular, ureteric, or neural involvement may be the initial manifestations. L Breast desmoid tumors o Desmoid tumors account for 0.2% of primary breast tumors, developing from muscular fasciae and aponeuroses. o Desmoid tumors may mimic breast cancer.
