differential diagnosis

Last reviewed 11/2020

There are four common diseases which give a very similar clinical picture to gastric carcinoma: that of a patient with a anorexia, weight loss, a slight lemon tinge on examination, and anaemia.

These diseases are:

  • carcinoma of the caecum
  • carcinoma of the pancreas
  • pernicious anaemia
  • uraemia

They form a quintet with gastric carcinoma which should always be considered together.

The principal differential for a gastric carcinoma is a gastric ulcer. In fact the gastric carcinoma may have originated from a previous gastric ulcer. A histological diagnosis of a gastric carcinoma must be made.
