Neuromuscular and vascular hamartoma of small bowel presenting as inflammatory bowel disease.

We present the case of a rare hamartomatous condition of the small intestine clinically mimicking inflammatory bowel disease. Disorganised fascicles of smooth muscle derived from both muscularis mucosae and propria, bundles of non-myelinated nerve fibres with groups of abnormal ganglion cells, and haemangiomatous vessels were present within the submucosa of a long segment of small intestine causing subacute obstruction.
