Aleukemic leukemia cutis is a rare condition characterized by the infiltration of the skin by leukemic cells before their appearance in the peripheral blood. The authors report a case of aleukemic leukemia cutis in a 30-year-old seemingly healthy man who presented with multiple skin papulonodular lesions and lack of peripheral blood involvement. Histopathologically, the skin infiltrates showed prominent granulomatous features that masked the underlying malignant process. Immunophenotypic studies of skin and bone marrow infiltrates revealed the myelomonocytic lineage of the atypical cells, consistent with M4 acute myelomonocytic leukemia. The authors emphasize the value of immunohistochemical studies in diagnosing a cutaneous atypical infiltrate and discuss problems of histopathologic differential diagnosis.

D017254	Leukemic Infiltration	A pathologic change in leukemia in which leukemic cells permeate various organs at any stage of the disease. All types of leukemia show various degrees of infiltration, depending upon the type of leukemia. The degree of infiltration may vary from site to site. The liver and spleen are common sites of infiltration, the greatest appearing in myelocytic leukemia, but infiltration is seen also in the granulocytic and lymphocytic types. The kidney is also a common site and of the gastrointestinal system, the stomach and ileum are commonly involved. In lymphocytic leukemia the skin is often infiltrated. The central nervous system too is a common site.	Infiltration, Leukemic,Infiltrations, Leukemic,Leukemic Infiltrations
D017444	Skin Diseases, Papulosquamous	A group of dermatoses with distinct morphologic features. The primary lesion is most commonly a papule, usually erythematous, with a variable degree of scaling on the surface. Plaques form through the coalescing of primary lesions.
