/span>ycosis fungoides (MF) is an epidermotropic, primary cutaneous T-cell lymphoma (CTCL) characterized by infiltrates of small to medium-sized T lymphocytes with cerebriform nuclei. The term MF should be used only for the classical cases characterized by the evolution of patches, plaques and tumours, or for variants showing a similar clinical course.
