Intra-abdominal Desmoid Tumor

Desmoid tumors, aggressive fibromatosis, are neoplasms that rarely become malignant and do not metastasize. These tumors often infiltrate and destroy adjacent vital structures and organs. The exact etiology of these tumors is unknown, but there are three known factors associated with desmoid tumors: a genetic, a hormonal, and a physical factor related to trauma. As with this case, a sonogram is commonly the first diagnostic examination that is performed to determine the identity of the soft tissue tumor.
