The specimen is an opened portion of small bowel. There is a bilobed tumour nodule situated
within the wall of the bowel. The tumour is predominantly submucosal in location and projects
into the lumen of the bowel. The tumour mass appears to be in continuity with the muscularis
externa and has a significant subserosal component. Histology showed the tumour to consist of
smooth muscle fibres and collagenous fibrous tissue. There was no evidence of malignancy. The
features were those of leiomyoma of the small bowel.
