Erythema Elevatum Diutinum (EED) is a rare chronic form of leukocytoclastic vasculitis, typically presenting with persistent erythematous to violaceous papules, nodules, and plaques localized on the extensor surfaces of the extremities. The bullous variant of EED is exceptionally uncommon, characterized by the formation of tense bullae or vesicles atop existing lesions, which may ulcerate and become secondarily infected. The patient experienced significant clinical improvement of the lesions following therapy. This case underscores the importance of recognizing atypical presentations of EED, especially in patients with underlying autoimmune disorders, and highlights the effectiveness of dapsone in managing refractory cases.
