One biopsy per patient was assessed in 64 cases. Two biopsies corresponding to two different lesion types (plaque and tumor) were evaluated in one patient with tumor-stage MF.

^**

Tonsil tissue from 5 distinct individuals was obtained as de-identified specimens. Human CTCL cell lines were originally derived from an MF plaque ^b and from the peripheral blood of patients with SS ^c or with an unspecified leukemic-stage CTCL ^d.

^***

Mean age [±SD] of patients at time of cell harvest: 66 [±11].

BIDs: benign inflammatory dermatoses; CTCL: cutaneous T-cell lymphoma; MF: mycosis fungoides; SS: Sézary syndrome.
