Clonality for the T-cell receptor (TCR) assessed by polymerase chain reaction for TCR gamma chain gene rearrangements using formalin-fixed paraffin-embedded sections according to the established BIOMED-2 protocol (24). Identical peaks obtained from skin and breast lesions, suggesting the presence of the same TCR gene rearrangement (black arrow).
