Underlying chronic myeloid leukaemia was diagnosed. The management of this complex case was difficult, and the patient demised. This case illustrates that in patients with an acute febrile illness with haemorrhage, a thorough history and examination, as well as a high index of suspicion for concurrent conditions, is important.en© 2017 The Author(s).
