MRCP2-2209

A 54-year-old woman presents to her GP with concerns from her carer about her increasingly prominent gums over the past few months. The patient has learning difficulties and lives in a care home. She has had three recent infections and has been experiencing fatigue and shortness of breath with minimal activity. On examination, she has hypertrophic bleeding gums, anaemia, multiple bruises, a flow murmur, and mild splenomegaly. Blood tests reveal a raised white cell count, low neutrophil count, thrombocytopenia, and increased blast cells with Auer rods. What is the most likely diagnosis?
