[Immunocytological study of cutaneous malignant lymphomas. Classification (author's transl)].

The malignant cutaneous lymphomas come into the category of hematodermias but can equally be considered as an abnormality of the immune system. Having described the methods used in the immunocytological investigation of 21 lymphomas and 3 pseudolymphomas, the authors expound their classification of malignant cutaneous lymphomas before stating the results obtained in immunocytological studies in each of the groups. They show how formal separation between epidermtropic malignant cutaneous lymphomas and non-epidermotropic malignant cutaneous lymphomas can be confirmed by immunocytological and ultrastructural facts.
