The aim of the school is to update the medical specialists involved (dermatologists, pathologists, haematologists, radiotherapists, oncologists) in the diagnosis, management, and treatment of primary cutaneous lymphomas. The latter are the second most common type of extra-nodal lymphoma (accounting for about one third of the total number of non-Hodgkin’s lymphomas) and show definite peculiarities in terms of clinicopathological features, behaviour, and response to treatment.
