TCR-γ analysis of concurrent MF skin biopsy specimens showing a common clonal GR.

(A) A skin sample obtained from the right thigh showed a dominant TCR-γ gene rearrangement (GR) of 228 bp using the VγI primer. (B) The second specimen, obtained from left-thigh skin, showed an identical dominant T-cell GR (same Vγ family and the same size). Asterisks indicate TCR-γ GRs. The red peaks without asterisks correspond to internal size standards. Red indicates VγI; blue, VγII; black, VγIII; and green, VγIV.
