Summary
Angioimmunoblastic lymphadenopathy (AILD) is a rare condition that can mimic tuberculosis, leading to misdiagnosis. This case highlights the importance of lymph node biopsy for accurate AILD diagnosis, especially with pulmonary involvement.
Area of Science:
- Immunology
- Pathology
- Pulmonology
Background:
- Angioimmunoblastic lymphadenopathy (AILD) is an uncommon T-cell mediated lymphoproliferative disorder.
- AILD often presents with constitutional symptoms and lymphadenopathy, making differential diagnosis challenging.
- Clinical and radiological features of AILD can overlap with infections like tuberculosis and other lymphomas.
Observation:
- A patient presented with symptoms suggestive of pulmonary involvement.
- Initial fine needle aspiration cytology was misinterpreted as tuberculosis, leading to empiric antituberculous treatment.
- The patient received three months of antituberculous therapy without clinical improvement.
Findings:
- A subsequent lymph node biopsy definitively diagnosed Angioimmunoblastic lymphadenopathy (AILD).
- This confirmed AILD as the underlying cause of the patient's pulmonary and systemic symptoms.
- The case underscores the diagnostic difficulties in distinguishing AILD from other conditions.
Implications:
- Accurate and timely diagnosis of AILD is crucial for appropriate management.
- Lymph node biopsy remains a critical diagnostic tool for suspected AILD, especially when initial investigations are inconclusive.
- Awareness of AILD's potential to mimic other diseases like tuberculosis is essential for clinicians.
