Figure 2. Histopathological findings of annular erythema
(a) A monotonous dense infiltration is observed around vessels and
adnexa in the dermis and subcutaneous tissue (hematoxylin-eosin stain,
loupe image). (b) Mononuclear cells with dense chromatin and mild atypia
in the nucleus are present. A few mitotic cells are observed
(hematoxylin-eosin stain, ×1000). (c, d, e) Immunohistochemical analysis
(×400). Infiltrating cells are reactive to the anti-CD79α antibody (c),
CD10 (d), and terminal deoxynucleotidyl transferase (e).
