(a) A photomicrograph showing a dense diffuse lymphocytic infiltrate in the upper and mid dermis with no particular adnexotropism. The inset reveals these atypical lymphocytes mainly arranged in an interstitial pattern (H & E: 100x and 400x). (b) A photomicrograph showing lymphocytic infiltrate weakly positive for T-cell marker CD8 (IHC: 400x). (c) A photomicrograph showing lymphocytic infiltrate strongly positive for T-cell marker CD4 (IHC: 400x). (d) A photomicrograph showing negative expression of B-cell marker CD20 (IHC: 400x).
