Resumen de Polymorphic Erythematous Macules and Plaques With Dysesthesia
Cesar Daniel Villarreal-Villarreal, Jorge Ocampo Candiani, Oliverio Welsh
A woman in her 50s with a 2-year history of disseminated dermatosis involving the trunk and limbs was seen in our dermatology department. The dermatosis was characterized by polymorphic erythematous macules and plaques with elevated and indurated borders without evanescence to pressure (Figure, A and B). She was referred from another clinic with the presumptive diagnosis of urticarial vasculitis. Previous treatment included antihistamines and oral corticosteroids for several months without improvement. Dysesthesia was recorded on her lesions. Results from complete blood cell count, erythrocyte sedimentation rate, and blood chemistry analyses were normal, as was a thyroid profile. A punch biopsy specimen from a trunk plaque was obtained, and histopathological analysis was performed (Figure, C and D).
