[Kaposi's sarcoma arising in a patient with chronic myelomonocytic leukaemia].

We present the case of a 84 year-old man from north Portugal with chronic myelomonocytic leukaemia (diagnosed 2 years ago), treated with erythropoietin and hydroxyurea. The patient was referred to our department due to brown macules, papules and patches with a smooth surface and whitish scaling, located in the lower limbs that had appeared two months ago. The diagnosis of Kaposi's sarcoma was histologically confirmed. He was HIV-1/HIV-2 negative and had no analytic detectable immussupression. The patient died a short time after the diagnosis before we could start treatment.
