abstract：BACKGROUND:The Fli-1 transcription factor functions in cellular proliferation and tumorigenesis. Its role in various neoplasms and its presence in lymphocytes suggest a link between Fli-1 dysregulation and the pathogenesis of mycosis fungoides (MF). In this study, we further elucidate this possible link. METHODS:Secti...

Unlike classic MF where atypical lymphocytes show a predilection for the epidermis (epidermotropism), follicular MF displays a malignant lymphocytic infiltrate tropic for hair follicles (folliculotropism). This malignant lymphocyti...
