Secondary immune thrombocytopenia (ITP) as an initial presentation of Whipple's disease.

Immune thrombocytopenia (ITP) is a heterogeneous autoimmune disease characterized by low platelet count that has been associated with a number of chronic infections but rarely described as a manifestation of Whipple's disease (WD). We present a case of Whipple's disease in a patient initially diagnosed with ITP. A 46-year old male in the fifth decade of life presented with presumed idiopathic ITP and was treated with several therapies including corticosteroids, rituximab, and thrombopoietin receptor agonists.
