[Granulocytic sarcoma: apropos of 7 case reports]

Area of Science:

• Hematology
• Oncology
• Pathology

Background:

• Granulocytic sarcoma (GS), a rare extramedullary tumor of myeloid blasts, presents with varied clinical manifestations.
• Accurate diagnosis of GS is crucial for appropriate patient management and prognosis.

Observation:

• Seven cases of granulocytic sarcoma with distinct clinical presentations were analyzed.
• Diagnostic methods include tumor biopsy, antilysozyme immunoperoxidase technique, and ASD chloroacetate esterase staining.
• Immunohistological staining aids in identifying intra-cellular or surface antigens for GS recognition.

Findings:

• The study confirms the utility of various staining techniques in diagnosing granulocytic sarcoma.
• Different clinical presentations highlight the heterogeneous nature of GS.

Implications:

• The prognostic significance of GS is discussed in the context of these diverse cases.
• Early, aggressive treatment combining chemotherapy and local radiotherapy is proposed for isolated granulocytic sarcoma.
