29-year-old female with desmoid tumor on abdominal wall.
With history of one cesarian section 2 years ago.
Although desmoid tumors most commonly arise from the rectus abdominis muscle in postpartum women and in scars due to abdominal surgery, they may arise in any skeletal muscle.
The cause of desmoid tumors is uncertain and may be related to trauma or hormonal factors, or they may have a genetic association.
An endocrine etiology is suggested. Desmoid tumors most commonly appear in young women during or after pregnancy.
Note bulge or mass on the left lower quadrant of abdomen and cesarian scar.
