[Cancer of the colon and pregnancy: a new case]

The authors report a first case of cancer of the colon which showed itself by parietal inflammation during pregnancy. They point out the difficulty of the diagnosis which is not usually found until complications supervene because of the mildness of the symptoms and the difficulty in carrying out appropriate tests because of the presence of the fetus. The prognosis is very bad and the modalities of treatment that can be adopted in the presence of the gravid uterus alter depending on the length of gestation. For a patient who has not been previously prepared and the discovery is made during an exploratory laparotomy the first essential is to perform an ostomy to divert the intestinal contents.
