Chloroma
A chloroma is a solid tumor composed of immature white blood cells called myeloid precursor cells. They are most often found in acute myelocytic leukemia (AML) but may be found in other myeloproliferative disorders such as polycythemia vera, hypereosinophilia , and myeloid metaplasia . Chloromas get their name from the Greek chloros (meaning green) since these tumors often have a green tint due to the presence of myeloperoxidase. Chloromas may be seen under the skin, around the eyes, or in the mouth. They are often very tender. Treatment is usually radiation therapy as chloromas are exquisitely sensitive to low doses of radiation.
