chloroma

Description

A rare, cancerous (malignant), green-coloured tumour that develops with myelogenous leukemia. It is formed by the buildup of abnormal blast cells (immature blood cells) that collect in soft tissue outside the bone marrow.

Chloromas develop most often in the bone, skin, lymph nodes, breast, ovary, meninges (membranes that cover and protect the brain or the spinal cord) and around the eye.

Also called extramedullary leukemia or granulocytic sarcoma.
