Summary
Sézary syndrome, a rare T-cell lymphoma, presents with skin redness and abnormal blood cells. This case study confirms diagnosis through cell identification and lymph node analysis.
Area of Science:
- Dermatology
- Hematology
- Oncology
Background:
- Sézary syndrome is a malignant proliferation of mature T-cell lymphocytes.
- It is a rare form of cutaneous T-cell lymphoma, similar to mycosis fungoides.
- Key features include exfoliative erythroderma and Sezary cells in peripheral blood.
Observation:
- A 70-year-old woman presented with itchy, exfoliative erythroderma, subcutaneous nodes, and lymphadenopathy.
- Clinical suspicion for Sézary syndrome was high based on presenting symptoms.
Findings:
- Diagnosis was confirmed by identifying Sezary cells in peripheral blood via cytochemistry and membrane marker studies.
- Lymph node histopathology further supported the diagnosis.
- Genotypic studies ruled out HTLV-I/II and confirmed the monoclonal T-cell origin.
Implications:
- This case highlights the diagnostic process for Sézary syndrome.
- Accurate diagnosis is crucial for appropriate management of this rare lymphoma.
- Understanding the monoclonal T-cell origin aids in disease classification.
