Insights
Orbital granulocytic sarcoma, a rare complication of acute myeloid leukemia (AML), can present as bilateral proptosis in children. Prompt diagnosis and chemotherapy with steroids led to complete remission in a pediatric case.
Area of Science:
- Oncology
- Ophthalmology
- Hematology
Background:
- Granulocytic sarcoma is a rare orbital complication of acute leukemia, primarily affecting children under 10 with acute myeloid leukemia.
- Diagnosis involves clinical examination, CT scans, and hematological investigations.
- Treatment combines chemotherapy and intravenous steroid therapy.
Observation:
- A 6-year-old girl presented with bilateral proptosis, indicative of acute myeloid leukemia.
- The patient received a two-phase chemotherapy regimen combined with intravenous steroids.
Findings:
- The treatment resulted in complete remission after a 24-month follow-up period.
- This case highlights the successful management of orbital granulocytic sarcoma in a pediatric patient.
Implications:
- Orbital masses of uncertain origin, especially bilateral ones, warrant consideration for granulocytic sarcoma.
- Special stains and immunohistochemistry are crucial for accurate diagnosis of granulocytic sarcoma.
Background:
Granulocytic sarcoma is a rare orbital complication of acute leukemia. It concerns primarily children under 10 years of age suffering from primitive acute myeloid leukemia. The diagnosis is made by clinical examination, computed tomography and confirmed by haematological investigations. The treatment approach is based on chemotherapy associated with intravenous steroid therapy.
Case Report:
We report the case of a 6-year-old girl who presented with bilateral proptosis revealing acute myeloid leukemia. The patient was treated by a combination of chemotherapeutic drugs in two phases, associated with intravenous steroids. After a follow-up period of 24 months, the patient was in complete remission.
Conclusion:
The diagnosis of granulocytic sarcoma should be considered in any orbital mass of uncertain origin, particularly if it is bilateral. Special stains and immunohistochemistry play an important role in the diagnosis.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
