Recurrent Rash and Anemia: A Diagnostic Challenge of Angioimmunoblastic T-cell Lymphoma Mimicking Parvovirus B19 Infection.

Angioimmunoblastic T-cell lymphoma (AITL) is a rare and challenging subtype of T-cell lymphoma often presenting with skin rashes and difficult diagnostic features. Its presentation can mimic other conditions, complicating accurate diagnosis. This case shows AITL in a 74-year-old man initially presenting with anemia that mimicked pure red cell anemia caused by parvovirus B19. The patient exhibited direct Coombs-positive anemia and recurrent urticarial-like rashes, which were initially misleading. This case emphasizes the critical need for considering lymphoma in patients presenting with direct Coombs-positive anemia and recurrent urticarial-like rashes It underscores the importance of revisiting and thoroughly assessing medical histories to enable accurate diagnosis, even when initial presentations suggest alternative diagnoses. Early recognition and appropriate management of AITL are crucial for improving patient outcomes.
