Case Report: Development of Leukocytoclastic Vasculitis after Cardiac Stress Test with Technetium 99 Sestamibi

Leukocytoclastic vasculitis (LCV) is a small vessel vasculitis that presents most commonly as palpable purpura. In our case report we note a patient that develops LCV which progressed from purpura to painful necrotic ulcers after exposure to technetium 99 sestamibi. It has been hypothesized as a potential trigger but this case is the first to document it as such. We also propose that our patient’s extensive allergy history may have predisposed her to developing LCV.
