Reactivation of Epstein-Barr virus infection and polyclonal expansion of lymphocytes is well-documented in solid organ and hematopoietic stem cell transplant recipients and is considered a potential precursor to lymphoma. We report an analogous case of posttransplantation polyclonal lymphoproliferative disorder in a patient with human immunodeficiency virus infection who was successfully treated with antiretroviral therapy.

Background: Clonal mature B-cell lymphoproliferative disorders (B-LPDs) are a heterogeneous group of neoplasia characterized by the proliferation of mature B lymphocytes in the peripheral blood, bone marrow and/or lymphoid tissues. B-LPDs classification into different subtypes and their diagnosis is based on a multiparametric approach. However, accurate diagnosis may be challenging, especially in cases of ambiguous interpretation.

Introduction: Castleman's disease (CD) represents a rare polyclonal lymphoproliferative disorder characterized by atypical lymph node hyperplasia, the precise etiology of which remains undefined. Pancreatic involvement of CD is particularly uncommon and often misdiagnosed due to its nonspecific clinical features, making it difficult to distinguish from tumors with abundant blood supply such as solid pseudopapillary tumors and neuroendocrine tumors. Multimodal imaging plays a crucial role in diagnosing pancreatic CD and determining the extent of lymph node involvement.

Castleman disease (CD) is a rare lymphoproliferative disorder encompassing a spectrum of conditions with distinct histopathological findings and varied clinical presentations. Diagnostic challenges are often encountered due to overlapping features with other malignancies, infections, and autoimmune disorders. Idiopathic multicentric Castleman disease (iMCD) is a subtype of CD, characterized by generalized lymphadenopathy, polyclonal lymphoproliferation, systemic inflammation, and a cytokine storm that can be life-threatening.

Idiopathic multicentric Castleman disease (iMCD) is a rare, life-threatening subtype of Castleman disease (CD), which describes a group of rare, polyclonal lymphoproliferative disorders that demonstrate characteristic histopathology and variable symptomatology. iMCD involves a cytokine storm that occurs due to an unknown cause. Rapid diagnosis is required to initiate appropriate, potentially life-saving therapy, but diagnosis is challenging and impeded by clinical overlap with a wide spectrum of inflammatory, neoplastic, and infectious causes of generalized lymphadenopathy.
