Abstract
Autoimmune Lymphoproliferative syndrome is an inherited disorder manifesting with autoimmune cytopenia, lymphadenopathy and splenomegaly. The differential diagnosis includes infections, autoimmune disorders or malignancies. The disease is characterized by accumulation of double negative (CD3+CD4-CD8-) T cells (DNT) in the peripheral blood. Here we report the case of 19 years-old girl that was diagnosed as autoimmune Lymphoproliferative syndrome with a literature review.
