Background: An abdominal wall desmoid tumor is a rare event, has a strong tendency for local invasion and recurrence, and usually presents as an abdominal lump.
Case: A 35-year-old multiparous woman presented with a painful abdominal lump that had been slowly increasing in size. The pain was not associated with menstruation. Clinical examination, ultrasonography, and abdominal magnetic resonance imaging were performed and suggested a large, sharply defined mass measuring approximately 11 × 7.1 cm in the right anterolateral abdominal wall. There was no family history of familial adenomatous polyposis. The mass was excised and sent for histopathologic examination, which indicated abdominal wall desmoid tumor.
Conclusion: Abdominal wall desmoid tumors can be diagnostic dilemmas and should be considered in the differential diagnosis for lumps in the abdomen in women.
