ITP is being increasingly recognised secondary to SARS-CoV-2 infection in the current pandemic. Here, we report a case of a five-and-a-half-year-old female child on maintenance chemotherapy for acute lymphoblastic leukaemia who subsequently developed ITP secondary to SARS-CoV-2 infection. Our patient had prolonged thrombocytopenia secondary to ITP, requiring the use of second-line agents including romiplostim and eltrombopag. This is a unique case where ITP was recognised secondary to SARS-CoV-2. In such cases of thrombocytopenia, ITP should be considered as an important differential in addition to relapse of leukaemia or thrombocytopenia due to chemotherapy drugs.
