Small Intestine - Leiomyoma

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.
