BACKGROUND: Hypopigmented mycosis fungoides (HMF) is a rare subtype of mycosis fungoides (MF). We compared patients with exclusive hypopigmented lesions with a group of MF patients with concomitant different lesions.
METHODS: 20 patients with HMF only and 14 patients with hypopigmented lesions concomitant with other types of lesions (mixed MF, MMF) were selected. Clinical-epidemiological analysis as well as histological and immunohistochemical studies were performed.
RESULTS: HMF and MMF preserve some similarities, like predilection for dark-skinned persons and slow progression, but they also present differences: the exclusive variant is associated with early onset and a clear CD8+ immunophenotype, whereas MMF patients tend to present a predominance of CD4+ cell infiltrates. Histological analysis revealed similar findings; relapsing courses were common.
CONCLUSION: Whether patients are suffering from exclusive HMF or MMF, the presence of hypopigmented lesions can be considered a marker of good prognosis in MF, since both groups presented similar data, such as staging and disease duration.
