[Monocytic leukemias with unusual clinical presentations]

In clinical hematology the terms "monocytic" leukemia and "reticulosis" still -require better definition and classification. By presenting the histories of eight patients and by cytology and cytochemistry it is shown that myelo-monocytic leukemias can have the course well-known for an acute leukemia, including different skin lesions, as well as that of an typical chronic granulocytic leukemia. In dermatology monocytic leukemias were considered as belonging to the entity of the so-called reticulosarcomatosis cutis. However, strict differentiation from the hiary cell leukemia is to be made today. The general term "reticuloses" has quite faulty been used formerly for classification of these last two disorders.
