2 Figure 1 Hematoxylin-eosin staining, preputial LSA with strong lymphohistiocytic infiltrate, divided into an epidermotropic and a dermal part, both separated by a fibrosis zone. Scale bar: 100 μm.

3 Figure 2 Temperature gradient gel of TCR-γ PCR products of LSA skin samples. Lane 1, DNA molecular weight marker (HincII digest of φX 174 RF DNA); lanes 2, 6–9, polyclonal PCR products; lanes 3–5: clonal PCR products, appearing as sharp bands below the middle range of the gel (arrow), lane 10, PCR product of clonal control DNA (Jurkat T cell line).
