SMALL INTESTINE - Intussusception, secondary carcinoma

An ileo-ileal intussusception led by a tumour some 3 cm. in diameter, brownish in colour, and showing several nodular excrescences. The leading point appears to be ulcerated.
This man, at the age of 70, was found to have a carcinoma of the left lower lobe of the lung, which was treated by radiotherapy. The following year he was admitted to hospital with nausea, anorexia and vomiting; the following day he developed abdominal pain and vomited faecal matter. He died three days after admission. At autopsy, the presence of a carcinoma of the lung was confirmed, there were secondary deposits in the liver, and this lesion was demonstrated in the ileum. Histologically, the present lesion is a secondary deposit from the carcinoma of the lung.
