Sebaceous gland necrosis induced by Demodex mites: a case report
Abstract
Demodex mites, including Demodex folliculorum and Demodex brevis, are obligate ectoparasites residing in the pilosebaceous units of human skin.1 Although typically asymptomatic, these mites can provoke inflammatory dermatoses in immunocompromised or predisposed individuals. Conditions, such as rosacea, blepharitis, and acne vulgaris, have been associated with increased mite density and subsequent inflammatory responses.1-3 Histopathological findings in such cases often reveal a dense perivascular and perifollicular lymphohistiocytic and neutrophilic infiltrate, with numerous Demodex mites in the follicular infundibula.
