title: Intracranial granulocytic sarcoma: two cases and literature review.
abstract: Intracranial granulocytic sarcoma was a relatively rare tumor composed of myeloid blasts and/or immature myeloid cells in an extramedullary site which is associated with acute/chronic myeloid leukemia. In this paper, two cases of intracranial granulocytic sarcoma, one male aged 36 and one 28-year-old female, were reported to improve the diagnosis and treatment of such diseases. Diagnostic and treatment procedures for them were retrospectively summarized and relevant literature reviews were combined. Pathological biopsy was conducted to validate the diagnosis. Surgical resections in combination with chemotherapy were performed. The differential diagnosis of intracranial granulocytic sarcoma from malignant lymphomas and alternative small round cell malignancy was confirmed by biopsy and immunohistochemistry.
