Diagnostic Dilemma: An Unusual Case of Angioimmunoblastic T-Cell Lymphoma Manifesting as Bone Marrow Non-Caseating Granuloma.

We present here a rare and unusual presentation of angioimmunoblastic T-cell lymphoma with non-necrotizing granuloma of bone marrow. We did not find any case reports of such case in our literature search. A 77-year-old man presented with shortness of breath, generalized weakness, fatigue and weight loss. Laboratory data revealed elevated white count, low platelets and anemia. Imaging studies revealed generalized lymphadenopathy. A bone marrow biopsy showed hypercellular marrow with non-caseating granuloma which was non-diagnostic and lymph node biopsy showed angioimmunoblastic T-cell lymphoma.
