Presentation

Abdominal discomfort.

Patient Data

Age: 40 years
Gender: Female

Oval right mid abdominal mass anterior to the hepatic flexure and contacting the anterior abdominal wall. Some surrounding stranding. 

Case Discussion

Ultrasound-guided biopsy confirmed a benign-appearing mass of smooth muscle origin, most likely a leiomyoma or benign smooth muscle proliferation, with IHC staining positive for smooth muscle actin, calponin and desmin. The fascicular arrangement did NOT support a desmoid tumor. This was managed conservatively due to the benign pathological features.
