A case of isolated granulocytic sarcoma of the kidney after complete remission of acute myelocytic leukemia / 대한비뇨기과학회지

ABSTRACT

Granulocytic sarcoma is an uncommon extramedullary tumor composed of granulocytic precursor cells such as myeloblasts or monoblasts. These tumor were originally called chloroman because of the green color imparted by the heavy concentration of the myeloperoxidase present in myelogenous leukemic cells. The tumor usually develops during the course of myelogenous leukemia or myeloproliferative disorders and may represent the initial manifestation of leukemia. Rarely, granulocytic sarcoma is recognized as an isolated tumor without any evidence of leukemia. We report a case of a 21-year-old man who was diagnosed as granulocytic sarcoma of right kidney after complete remission of acute myelocytic leukemia.
