I saw the surgeon today and we discussed what to do about the lymph node that could be seen on the CT. Thus far we have no explanation for it. Carcinoma and carcinoid seem to be ruled out. My favored explanation is that the NSAID I was taking was causing inflammation of the colon and this was a node reacting to the inflamation. Alternatively it could be an old TB node - I had a positive Mantoux when I was a teenager. Other possibilities could be lymphoma, though a single node just there would be very unusual and as a long shot, carcinoid producing something other than serotonin. I have hypercalcemia and parathormone producing carcinoids have been described. The options are laparoscopic biopsy now or repeat the CT scan in 3 months. I have opted for the latter, because even laparoscopy has a definite morbidity and I'm not sure that it is going to alter management
Increasingly abnormalities are being discovered on screening tests that don't amount to a hill of beans.
