Case Reports
Clinical Features
  • Thickened purple patches, plaques or nodules
Micro Description
  • Dense cellular infiltrate, often with a nodular outline, occupies the mid dermis
  • Deep dermis and subcutaneous fat may be involved
  • Typically spares the immediate subepidermis and hair follicles, forming a Grenz zone
  • Infiltrate is polymorphic, containing eosinophils, neutrophils and an admixture of plasma cells, mast cells and lymphocytes
  • Red cell extravasation is often present
  • Blood vessels appear dilated and their walls are infiltrated by eosinophils and fibrin deposition
  • Older lesions may show fibrosis and hemosiderin deposition
  • In late stage, histology resembles erythema elevatum diutinum
Positive Stains
  • Granular IgG at dermal-epidermal junction; also outlines the hair follicles and walls of blood vessels
  • Less often IgA and IgM are present
