what is the clinical appearance of erythema migrans?
Erythematous patches surrounded by a white or yellow border. Diffuse areas devoid of filiform papillae. Distinct presence of fungiform papillae. There appear to be remission and changes in the depapillated areas
Genetic factors may play a role in presence, may be caused by stress. Pt. may complain of burning discomfort. NO TREATMENT
Erythema migrans
Term used to describe “geographic tongue” found on mucosal surfaces other than tongue
