Age-specific cutaneous T-cell lymphoma incidence rates and age distributions at diagnosis from 2001-2005 in the 16 SEER registries by sex. (A-D) Rates per 1 million person-years are shown for (A) all cutaneous T-cell lymphomas (CTCL) combined, (B) mycosis fungoides (MF), (C) primary cutaneous peripheral T-cell lymphoma (pcPTL), and (D) cutaneous CD30⁺ lymphoproliferative disorders (CD30⁺ LPD). (E-H) Density plots are shown for (E) all CTCL combined, (F) MF, (G) pcPTL, and (H) CD30⁺ LPD. Area under the curve includes 100% of cases. The vertical axis for each density plot represents smoothed estimates of the density of patients (density × 100 = %).
