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

Abstract

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.
