Abstract

Solitary fibrous tumours (SFTs) and chronic myeloid leukaemia (CML) are both uncommon neoplasms with distinct chromosomal aberrations and clinical presentations. Here, we present a case of a male in his late 50s with a history of intracranial SFT who presented 8 years after subtotal resection and adjuvant radiotherapy with splenic infarcts, a white blood cell of 83 000 cells/mL, and liver masses. He was treated with dasatinib for CML and temozolomide/bevacizumab for SFT. This case emphasises the benefits of broad differential diagnoses that include multiple concurrent disease processes when confronted with unusual presentations. It highlights the need for interdisciplinary efforts and personalised approaches when managing patients with multiple primary malignancies.
