Leukocytoclastic vasculitis is the inflammation of small blood vessels due to leukocyte migration that comprises a wide range of differentials. It can be caused by autoimmune disorders, infections, neoplasms, or certain medications and warrants prompt recognition and therapy for optimal patient outcomes.

Case Presentation

Here we present a case of a 37-year-old male who presented with a painful, petechial rash on his torso and extremities. Skin biopsy revealed leukocytoclastic vasculitis, thereby prompting a comprehensive investigation into the underlying etiology leading to the diagnosis of Pseudomonas aeruginosa infective endocarditis.


Pseudomonas aeruginosa is a rare cause of infective endocarditis with a high mortality and morbidity rate. This case highlights the importance of taking a thorough history and physical along with a complete workup of vasculitis as the underlying cause can be life-threatening.
