Sterile Neutrophilic Folliculitis with Vasculopathy in a Young Male Patient with Infective Endocarditis

Sterile neutrophilic folliculitis with vasculopathy is a rare entity histopathologically characterized by neutrophilic or suppurative and granulomatous folliculitis accompanied by a folliculocentric vasculopathy. 1 It is described as a cutaneous manifestation of a systemic illness or infectious trigger, and its clinical features vary independently from the underlying medical illness. 1 Prompt identification may uncover an underlying systemic disease. Due to the rarity of this clinical entity, there is a paucity of evidence regarding its etiology, diagnosis, and treatment recommendations. We present a case of sterile neutrophilic folliculitis with vasculopathy in a 34-year-old male hospitalized for infective endocarditis.
