Lesions typically can be described as follows:

  • Primary lesions are edematous, erythematous papules or plaques with a pale center (wheal) and surrounding erythema (flare)

  • Lesions may be pale to red (depending on background skin color)

  • Lesions can be localized or generalized

  • Lesions may be round, oval, annular, arcuate, serpiginous, or generalized

  • Lesions resolve without postinflammatory pigmentary changes or scaling
