To the Editor:Chloroma is a rare solid tumor that was formed sometimes from malignant myeloid blast cells outside the hematopoietic system;these are known as chloroma or granulocytic sarcoma[1]Chloroma can be diagnosed anywhere outside of the hematopoietic system,such as the head and neck,skeletal system,breast,uterus,and central nervous system.[2]This tumor is common in leukemic patients.[3]Chloroma presents as an epidural mass resulting in spinal cord compression with neurologic symptoms.[4]Spinal lesions occur most frequently at the thoracic level;however,the most common primary symptoms are low back pain and radiating pain in the legs[5].
