[Mucin-producing signet ring cell carcinoma of stomach accompanied by microangiopathic hemolytic anemia and disseminated intravascular coagulation: a case report].

Diffuse bone marrow metastasis of carcinoma sometimes accompanies microangiopathic hemolytic anemia (MHA) which is characteristic with red cell fragmentation. We report on a 56-year-old male case of signet ring cell type gastric carcinoma complicated with MHA and DIC. Bone marrow aspiration disclosed the metastasis of carcinoma cells. However, no other distant metastasis was evident by pathological studies of autopsy samples.
