ABSTRACT

Cutaneous lymphomas represent a heterogeneous group of T-, NK- and B-cell neoplasms, with mycosis fungoides (MF) being the most common subtype. MF has a plethora of clinicopathological manifestations. Many variants of this lymphoma differ substantially from the ‘classical’ Alibert–Bazin disease and are therefore sometimes referred to as ‘atypical’ forms of the disease. This review addresses the whole clinicopathological spectrum of mycosis fungoides with respect to epidemiology, clinical, histopathological, immunophenotypic and genotypic features and the clinical course and prognosis of its variants: classical, erythrodermic, follicular, syringotropic, bullous/vesicular, granulomatous, poikilodermic, hypo- and hyperpigmented, unilesional, palmoplantar, hyperkeratotic/verrucous, vegetating/papillomatous, ichthyosiform, pigmented purpura-like, pustular and mucosal involvement in MF.
