Granulocytic sarcoma (chloroma): a report of two cases.
Granulocytic sarcoma or chloroma is defined as an extramedullary solid tumor, composed of granulocytic precursor cells at various levels of differentiation. Granulocytic sarcoma is mostly associated with acute and chronic leukemia, rarely with polycythemia vera and myelofibrosis. The use of special immuno-histochemical stains is mandatory, because this tumor is often misdiagnosed as malignant lymphoma. We report two cases of granulocytic sarcoma (tonsil and ovary) associated with chronic myelogenous leukemia. We describe the first reported association of atypical CML and granulocytic sarcoma.
