An elderly autopsy case of chronic myelomonocytic leukemia with infiltration of a giant liver cyst and multiple organs]

A 78-year-old man was referred to his local hospital at the beginning of July 2006 with low grade fever and cough, and was admitted on August 22 with pneumonia. Hematology tests on admission revealed leukocytosis, anemia, and thrombocytopenia, so he was subsequently transferred to our hospital on August 24. A diagnosis of chronic myelomonocytic leukemia (CMML) was made from the hematological findings and he was given hydroxycarbamide from September 7. Seventeen days later, abdominal CT revealed hemorrhage into a giant liver cyst, as well as both intraabdominal and intrathoracic hemorrhage. He died of hemorrhagic shock on September 25. Autopsy showed extensive infiltration of myelomonocytic leukemic cells into the walls of the liver cyst, as well as the pleura and multiple other organs. In summary, we report an elderly autopsy case of CMML with infiltration of a giant liver cyst and multiple organs.
