Leukaemia cutis preceding acute myelomonocytic leukaemia.

We report a case of acute myelomonocytic leukaemia (AMML) who presented with a striking leukaemic infiltration in the frontal area of the scalp that was also rapidly followed by infiltrates in other sites of the skin, mainly in the upper thoracic wall. Leukaemic skin infiltration developed independently of his haematological status; nevertheless, he rapidly progressed to acute leukaemia. We emphasise the importance of early recognition and identification of such lesions with a subsequent early application of systematic antileukaemic therapy.
