Adult pityriasis lichenoides‐like mycosis fungoides: a clinical variant of mycosis fungoides

Abstract

In patients with clinical features of longstanding PL and histological findings consistent with MF, differential diagnosis must include PL, LyP, and papular MF. As some forms of PL evolve towards MF and PL-like forms of MF, these patients should undergo regular follow-up and repeated biopsies in order to discard diagnoses of atypical forms of MF.
