| Abstract: | A patient with acute myelomonocytic leukemia is reported. He had presented erythroderma and atypical cellular infiltration of the skin 4 months prior to the detection of leukemia in the peripheral blood and bone marrow. Aleukemic leukemia cutis is a rare condition which is characterized by leukemic cells invading the skin prior to the observation of leukemic cells in the peripheral blood. The cases of aleukemic leukemia cutis reported in the literature show little or no conformity in their clinical appearance. Enzyme cytochemistry, immunocytological and electron-microscopic studies are of considerable help in differentiating the cutaneous infiltrates and in establishing early diagnosis. We report herein a patient with erythroderma which regressed spontaneously, whereas microscopic examination of a cutaneous biopsy showed atypical cells infiltrating the dermis. After a period of 3 months, during which the patient remained free of lesions, he showed recurrence of the erythroderma while developing acute myelomonocytic leukemia. We feel this unusual presentation of aleukemic leukemia cutis should be added to the evergrowing list of cutaneous manifestations of leukemia. |
