Leucocytoclastic Vasculitis: a perplexing diagnosis with a simple cure

Abstract

For such a puzzling diagnosis, Leukocytoclastic Vasculitis (LCV) has a relatively simple and effective cure. We present a case report of a male patient in his thirties with a rash on his left leg for around a year without a definite diagnosis. The eruption of the rash was likely related to his Covid-19 immunization. After an extensive workup, it was diagnosed as a case of Leukocytoclastic Vasculitis. It was then successfully treated with immunosuppressive therapy.

Physicians need to consider the possibility of leukocytoclastic vasculitis in patients presenting with a skin rash especially after starting a medication or getting immunized. The recent surge in Covid-19 vaccinations could mean an increased incidence of LCV, therefore physicians need to be more mindful of this possibility when evaluating a skin rash. A thorough history needs to be undertaken to identify the trigger responsible and a skin biopsy should be done as soon as possible to confirm the diagnosis and start treatment.
