Summary
A rare spinal granulocytic sarcoma (GS) can precede acute myelogenous leukemia. Early diagnosis of this epidural mass is crucial for timely treatment and preventing leukemic transformation.
Area of Science:
- Oncology
- Hematology
- Neurology
Background:
- Spinal epidural granulocytic sarcoma (GS) is a rare extramedullary manifestation of myeloid leukemia.
- It can present as a mass causing spinal cord compression.
Observation:
- A 10-year-old boy presented with leg weakness, initially misdiagnosed as histiocytic lymphoma.
- Bone marrow involvement was absent at initial presentation.
Findings:
- Retrospective immunoperoxidase staining for lysozyme confirmed spinal epidural GS fourteen months later.
- The patient subsequently developed acute myelogenous leukemia.
Implications:
- Spinal epidural GS should be considered in the differential diagnosis of epidural masses, even without overt leukemia.
- Early diagnosis and combined chemotherapy/radiation may avoid surgery and prevent leukemic progression.
