Primary cutaneous lymphomas háve been classified according to the classification of European Organi-zation for Research and Treatment of Cancer (EORTC) or World Health Organization (WHO). Even though both classifications represented a big progress in contrast to the former Revised European-American Lymphoma classification (REAL), they had some restrictions considering the dermatologists needs. That is why the representatives of both systems suggested a new classification of cutaneous lymphomas named WHO-EORTC. The páper gives a basic overview of the primary cutaneous lymphomas and two other neoplasms existing in the skin according to the new classification and discusses the differences be-tween two previous classifications. Secondary skin symptoms associated with systemic lymphomas and acute leukaemias are not mentioned here.
