Cytotoxic T-lymphocyte-associated protein 4 (CTLA4) haploinsufficiency (HI) is an immune dysregulation disorder characterized by T lymphocyte hyperactivation, and generalized lymphoproliferative and autoimmune disorders. Patients with CTLA4 haploinsufficiency are also prone to developing various malignancies. Due to the rare nature of this condition, the longitudinal evolution of CTLA4 haploinsufficiency clinical manifestations remains to be described. We report on over a decade-long course of a young adult men patient with known CTLA4 haploinsufficiency, who sequentially developed multiple autoimmune conditions along with two distinct episodes of classical Hodgkin Lymphoma (cHL) of unique histologies. Notably, the patient had serological and molecular evidence of Epstein Barr virus (EBV) infection at the time of diagnosis of both cHL. The allogeneic stem cell transplantation consolidated durable remission of cHL and CTLA-4 haploinsufficiency-related clinical manifestations, but failed to enable the patient to permanently suppress EBV viremia, which raises concerns for the development of other EBV infection-related conditions in the future. This case report adds on the current understanding of the natural clinical history of patients with CTLA4 haploinsufficiency, and their unique susceptibility to developing cHL.
