A mixed, superficial, perivascular dermal inflammatory infiltrate was also present (fig. 1).
Immunohistological findings of both PR cases. Diffuse immunoreactivity was present for CD2, CD3, CD4, CD43, and CD45R0, but labeling for CD7 was comparatively diminished. CD8+ lymphocytes were sparse and CD30 was absent.
