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).
