The specimen consists of a segment of small intestine, opened and somewhat distorted, to display
a polypoid tumour, some 4 x 3 cm., covered by mucosa, which shows patchy areas of haemorrhage
at the apex.
This man presented with vomiting, abdominal pain and constipation for six days. No
blood was demonstrated in the bowel motions. At operation, an intussusception in the mid-ileal
area was found, some 10 cm. in length, with the tumour shown here at the apex. The histology of
the lesion is of a simple leiomyoma.
