Characteristics and outcomes of 727 patients with mycosis fungoides and Sézary syndrome from a Brazilian cohort.

We observed a higher percentage of hypopigmented MF compared to the literature, and demographic (older age) and prognostic (poorer prognosis) similarities between erythrodermic MF and SS, suggesting a possible relationship between these erythrodermic lymphomas. Factors associated with a poorer prognosis were compatible with the literature.
