Abstract
A 76-year-old man was admitted to our hospital for constipation and lower abdominal pain. Colonoscopic examination revealed rectal cancer (pathological examination of a biopsy specimen revealed moderately differentiated adenocarcinoma). Although he had multiple liver and lung metastases, the rectum was mostly obstructed due to rectal cancer, and we performed laparoscopic anterior resection and lymph node dissection (D2). Before starting chemotherapy, lumbago and coxalgia appeared, and blood examinations revealed disseminated intravascular coagulation syndrome (DIC). Detailed examinations revealed disseminated carcinomatosis of bone marrow. He died on the 26th day after the onset of DIC.
Dissminated carcinomatosis of bone marrow with rectal cancer is rare. If therapy for DIC is not effective, the prognosis is very poor. There are some cases surviving with chemotherapy for this disease. Therefore, it is necessary to consider the treatment for this disease with accumulation of more case reports.
