[Disseminated carcinomatosis of the bone marrow occurring 11 years after subtotal gastrectomy for gastric cancer].
A 44-year-old man was admitted to our hospital because of purpura, increased serum alkaline phosphatase, and thrombocytopenia. He had undergone subtotal gastrectomy for gastric cancer 11 years earlier. A biopsy specimen of the bone marrow revealed metastatic mucin-forming, moderately differentiated adenocarcinoma. Because the primary tumor was not detected in any other organ, the gastric cancer the patient was treated for 11 years earlier was suspected as the primary tumor. Microangiopathic hemolytic anemia and disseminated intravascular coagulation developed during the clinical course, and the patient deteriorated despite treatment with anticoagulants. Finally, he died of pulmonary carcinomatous lymphangitis. Autopsy revealed a small number of adenocarcinomatous cells in the lymphoduct of the remaining stomach in spite of its mucosa being intact. We concluded that the bone marrow was infiltrated by cancer cells which originated in the stomach 11 years before. It is unclear why adenocarcinoma cells remained dormant for as long as 11 years in the gastric lymphoduct and bone marrow.
