ABSTRACT
Priapism is a rare complication of hematological diseases. Among leukemia, it is most frequently seen in patients with chronic myeloid leukemia, due to the high leukocyte counts that these patients achieve. We report a 22 years old male who presented with a priapism lasting more than 24 hours. Thirty six hours after admission and subsequent to a leukopheresis, penile relaxation was obtained. Despite good hematological response to therapy, an extensive penile and uretral necrosis, associated to an Acinetobacter infection, ensued between the fourth and fifth day of admission, that required surgical treatment

Patients and methods: Eight patients, our of 368, with acute myeloid leukemia that were studied in the Hematology Laboratory of a public hospital in Santiago, were classified as LMA-MO. Results: Blast cell morphology was undifferentiated or of subtype FAB-L2 lymphoblastic leukemia with medium sized blasts, agranular basophilic cytoplasm, reticular nuclear chromatin and a prominent nucleolus. Cytochemical staining was negative for peroxidase and esterases, immunophenotyping showed the expression of one or more myeloid antigens (CD13, CD33) and was negative for lymphoid antigens. Immunocytochemical expression of myeloperoxidase was positive in the three cases where it was performed. Only one patient achieved complete remission and is free of disease after 36 months of follow up. All other patients died without obtaining remission, six shortly after the onser and one 12 months after. Conclusions: The diagnosis of LMA-MO is essential considering its dismal prognosis
