[Colonic metastasis of diffuse signet ring cells gastric carcinoma].

The gastric cancer, despite its remarkable decline in incidence (1), still remains as one of the leading causes of death around the world (2) (7.2 to 20 deaths per 10 inhabitants per year) (3). The diffuse type (according to Lauren’s classification) with signet ring cells occasional presence, is less frequent but with worse prognosis than the intestinal, both commonly spread out via haematic and lymphatic (40-60%), (4), and being able to affect organs such as the liver (35-50%), lung (9-22%), bone (1,9%), and central nervous system (0,5-2%); being exceptional, without references, the involvement of other organs such as the colon, as in the case of the patient we report.
