title: Mycosis Fungoides Variants.
abstract: Mycosis fungoides (MF) is a cutaneous T-cell lymphoma that usually manifests as patches and plaques with a propensity for nonphotoexposed areas. MF is a common mimicker of inflammatory and infectious skin diseases, because it can be manifested with a wide variety of clinical and pathologic presentations. These atypical presentations of MF may be difficult to diagnose, requiring a high level of suspicion and careful clinicopathologic correlation. Within this array of clinical presentations, the World Health Organization classification recognizes 3 MF variants: folliculotropic MF, pagetoid reticulosis, and granulomatous slack skin. These 3 variants, as well as hypopigmented MF, are addressed in this article.
