Summary
Diagnostic cytologic features of natural killer (NK)/T-cell lymphoma were identified. Immunohistochemistry for CD56, TIA-1, and EBER are valuable diagnostic aids for this lymphoma.
Area of Science:
- Cytopathology
- Hematopathology
- Oncology
Background:
- Natural Killer (NK)/T-cell lymphoma is a rare and aggressive lymphoid malignancy.
- Accurate and timely diagnosis is crucial for effective patient management.
- Cytologic evaluation plays a role in the initial diagnosis of lymphomas.
Observation:
- Three cases of NK/T-cell lymphoma were analyzed for distinct cytologic features.
- Histologic correlation and immunohistochemical markers including CD56, TIA-1, and EBER in situ hybridization were utilized.
- Morphological characteristics included mixed-sized cells with eccentric nuclei, prominent nucleoli, and abundant cytoplasm.
Findings:
- Common findings were mitotic figures, necrotic debris, and tingible body macrophages.
- Lymphoma cells appeared more shrunken in fluid samples.
- Immunohistochemistry confirmed CD56, TIA-1, and EBER positivity in one case.
Implications:
- Specific cytologic features can aid in the diagnosis of NK/T-cell lymphoma.
- Immunohistochemistry is a critical adjunct for confirming the diagnosis.
- Enhanced understanding of cytologic morphology improves diagnostic accuracy for this lymphoma subtype.
