[Value of imprint in bone marrow morphological examination]

Area of Science:

• Hematology
• Diagnostic Pathology
• Cytology

Context:

• Bone marrow examination is crucial for diagnosing hematological disorders.
• Traditional methods include bone marrow smears and sections, each with limitations.
• Bone marrow imprints offer a combined advantage of both techniques.

Purpose:

• To evaluate the diagnostic utility of bone marrow (BM) imprints in hematological diseases.
• To compare the diagnostic accuracy of BM imprints against BM smears and sections.
• To analyze the correlation of tumor cell infiltration patterns in lymphoma and plasma cell myeloma (PCM) using BM imprints.

Summary:

• A study of 3024 bone marrow samples found BM imprints superior to smears for cellularity evaluation.
• BM imprints demonstrated higher diagnostic accuracy for conditions like hypersplenism, myeloproliferative neoplasms, and plasma cell myeloma compared to smears.
• BM imprints also showed better diagnostic accuracy than biopsy sections for megaloblastic anemia, acute myeloid leukemia, and myelodysplastic syndromes.

Impact:

• Bone marrow imprints provide a more accurate and comprehensive assessment of hematological diseases.
• This technique enhances the diagnostic capabilities in hematopathology, potentially leading to earlier and more precise diagnoses.
• The findings support the integration of BM imprints as a primary diagnostic tool in hematological evaluations.
