	The operative specimen consisted of 12 cm of distal ileum, appendix, cecum and colon. On opening the bowel there was a 4.5 x 3 x 3-cm elliptical submucosal mass at the ileocecal valve that had produced partial obstruction. Several small (2 mm) submucosal masses were found in the cecum nearby. On cut section each lesion was found to be firm, gray-tan and homogeneous involving the muscular wall of the bowel and adjacent mesentery.

−	The operative specimen consisted of 12 cm of distal ileum, appendix, cecum and 50 cm of colon. The ileum was mildly dilated and its wall hypertrophied. On opening the bowel there was a 4.5 x 3 x 3-cm elliptical submucosal mass at the ileocecal valve; this had produced partial obstruction. Several small (2 mm) submucosal masses were found in the cecum nearby. On cut section each lesion was found to be firm, gray-tan and homogeneous involving the muscular wall of the bowel and adjacent mesentery. The appendix and colon showed no lesions.
