Molecular genetic analyses of human endogenous retroviral elements belonging to the HERV-P and -R family in Primary Cutaneous T-Cell Lymphomas

Abstract

Mycosis fungoides (MF) is characterized by longstanding, scaly patch lesions preferentially involving the buttocks and body areas infrequently exposed to sunlight and by a slow evolution over years from patches to plaques and eventually tumors or erythroderma. Lymph node and visceral involvement, as well as large cell transformation, frequently occur in the late stages of the disease [1]. Sézary syndrome (SS) is an erythrodermic cutaneous T-cell lymphoma (CTCL) with leukemic involvement, an aggressive clinical behavior and poor prognosis [2].
