Small bowel melanoma.
A 51-year-old woman who presented with a two-week history of colicky
abdominal pain and change in bowel habit - with intermittent diarrhoea.
Her abdominal pain was brought on by eating. Fifteen years earlier a
malignant melanoma had been excised from under her left breast. Four
years ago she underwent a left mastectomy for cutaneous melanoma. Two months
before the current admission she underwent cardiac surgery for what was
thought to be an atrial myxoma - and proved to be melanoma.
On this occasion the examination was unremarkable, with no evidence of
metastatic disease. A CT scan was performed. This slice shows an
intussusception. There is contrast in the small bowel surrounding (the
intussuscipiens) the intussusceptum.
At operation she was found to have a mid-jejunal intussusception. An
enlarged (and black) mesenteric node can be seen.
