ABSTRACT
Introduction: Angioimmunoblastic T-cell lymphoma (AITL) is an aggressive subtype of peripheral T-cell lymphoma (PTCL) characterized by systemic disease. It is a rare subtype of non-Hodgkin’s lymphomas. However, it forms a major subset of PTCL. Lymph node is the primary site of disease and virtually all patients present with generalized lymphadenopathy. Case report: A 42-year-old male presented with fever of short duration and a solitary axillary lymph node swelling on the right side. Systemic examination revealed moderate ascites and hepatosplenomegaly. Hematological investigations showed pancytopenia and abnormal liver function. Axillary lymph node showed histological features suggesting AITL and was confirmed by a panel of immunohistochemistry (IHC). Conclusion: AITL presenting as solitary axillary lymph node enlargement is unusual. Such atypical presentation mandates careful clinical and laboratory evaluation. IHC is an effective ancillary tool for confirmation of diagnosis of this distinct clinicopathological entity.
