[Myelophthisis and gastric cancer. An unusual association].

The infiltration of the bone marrow y non-hematopoietic cells is called myelophthisis. In patients with gastric cancer, this invasion is extremely infrequent and the survival is usually less than three months. We present the case of a 35-year-old man with bone marrow involvement secondary to diffuse gastric carcinoma of signet ring cells.
