A rare case of immune thrombocytopenia secondary to breast cancer

Immune Thrombocytopenic Purpura (ITP) occurs in 2‐4/100000 adults and results in thrombocytopenia with variable bleeding symptoms.1 An association of ITP with lymphoproliferative disorders is well known and comprises up to 30% of cases of secondary ITP.2 Paraneoplastic secondary ITP in solid tumors is less well known but has been described,3 including in breast cancer patients.4 A correlation between the clinical courses of ITP and of solid tumor was infrequently observed. We describe the case of a patient presenting with ITP shortly after diagnosis of a localized breast cancer, who achieved complete remission of ITP after curative surgery of breast cancer despite rapid weaning of oral steroid therapy.
