| Abstract | Angioimmunoblastic T-cell lymphoma (AITL) is a subtype of peripheral T-cell lymphoma with a nonspecific clinical presentation. Cutaneous manifestations of AITL are variable and include morbilliform eruptions, urticaria, papulonodules, and erythroderma. We present the case of a 74-year-old male with a medical history of AITL presenting with diffuse erythematous macules and papules coalescing into patches and plaques on the trunk and bilateral upper extremities. Histopathology demonstrated a mild perivascular lymphocytic infiltrate in the dermis. By immunohistochemistry, the lymphocytic infiltrate was strongly positive for programmed cell death protein 1 (PD-1) (CD279) as well as cluster of differentiation 3 (CD3), CD5, and (focally) B-cell lymphoma-6 (BCL-6). Many cells within the infiltrate were positive for Epstein-Barr virus (EBV) by in situ hybridization. Additionally, a bone marrow biopsy demonstrated an atypical lymphoid infiltrate with T-cell predominance, many EBV-positive cells, and clonal T-cell receptor (TCR) beta gene rearrangement. Based on these histopathological findings, a diagnosis of recurrent AITL with cutaneous involvement was made. This case is a rare example of skin findings presenting as a first sign of recurrent AITL. |
