13478              GIANT HYPERTROPHY OF JEJUNAL RUGAE

This is a surgical specimen from a male patient who had recurrent abdominal pain with vomiting for 3 years.  On the last two occasions a mass could be felt in the upper abdomen. Laparotomy during one of the obstructive episodes showed a high jejunal intussusception involving about 25cms of the bowel.  Resection with end-to-end anastomosis was carried out.

The specimen is the resected 10 cms of jejunum opened to disclose a polypoid mass of hypertrophied rugae projecting into the lumen from the circular folds of the jejunum.  This mass formed the head of the intussusception.  Histology shows no evidence of malignancy.
