Abstract
A 26-year-old woman was admitted to our hospital because of transverse colon cancer which was pointed out at another hospital when she visited for constipation. Laboratory data showed thrombocytopenia, myelocytes in the peripheral blood, and increase in the tumor marker (CEA, CA19-9). Barium enema study revealed long stenosis of the transverse colon. Abdominal CT scan demonstrated peritonitis carcinomatosis. Bone scintigraphy revealed multiple abnormal uptake of isotope in the entire skeleton. We diagnosed bone marrow carcinosis, peritonitis carcinomatosis, and DIC due to colon cancer. Anticancer treatment and thrombolytic therapy were started. One time, improvement of the symptom and decrease in the tumor markers were seen, but she died 6 months later. We report this a rare case of juvenile colon cancer with bone marrow carcinosis with a review of the literature.
