Granulocytic sarcoma of the uterine cervix

Granulocytic sarcoma (GS) is a rare manifestation of leukemia and has been reported in 3-5% of acute myelogenous leukemia (AML) patients. GS in the uterine cervix is very rare and is also called chloroma because of its greenish appearance. We present the case of a patient whose disease relapsed as chloroma of the uterine cervix after bone marrow transplantation (BMT). She remained in continuous complete remission for 2 years after allogeneic BMT. However, she visited the hospital because of painless vaginal bleeding. She was diagnosed as having chloroma by cervical smear and colposcopically directed biopsy of the cervix. Systemic chemotherapy was administered on the presumption that myelogenous leukemia had recurred as chloroma, and a good clinical response was achieved. We describe the first case of AML that relapsed as chloroma of the uterine cervix after complete remission of the AML, which had complete response to only systemic chemotherapy.
