An autopsy case of disseminated carcinomatosis of the bone marrow from esophageal adenocarcinoma.

Key Clinical Message: Disseminated carcinomatosis of the bone marrow is rare. We present such a case, which is useful for raising awareness about the importance of early diagnosis and treatment of carcinomas complicated by disseminated carcinomatosis of the bone marrow. Abstract: This is the first autopsy report of disseminated carcinomatosis of the bone marrow (DCBM) in esophageal adenocarcinoma. Advanced poorly differentiated adenocarcinoma with signet ring cell carcinoma arising in Barrett's esophagus caused disseminated intravascular coagulation (DIC) with extensive bone marrow metastasis, resulting in death from cerebral hemorrhage. Although DCBM due to malignancy is rare with poor prognosis, it should be considered in malignancies associated with DIC, and prompt initiation of chemotherapy is the only way to improve the patient's prognosis.
