Abstract
Oxaliplatin-induced immune thrombocytopenia is a rare manifestation of oxaliplatin hypersensitivity, presenting as an acute onset of severe thrombocytopenia after oxaliplatin administration. No standard therapeutic approach outside of permanent discontinuation of oxaliplatin exists. Here, we present a case of oxaliplatin-induced immune thrombocytopenia occurring after oxaliplatin retreatment for metastatic colon cancer. Possible mechanisms of disease and approach to treatment are discussed.
