Abstract: 【Abstract】 Erosive pustular dermatosis of the scalp （EPDS） is a rare superficial skin inflammatory disease that occurs on the scalp, and its pathogenesis is still unclear. Its clinical manifestations are similar to those of infectious inflammation and malignant tumors, and its diagnosis is highly dependent on non-specific pathological changes, so the diagnosis is relatively difficult. Clinically, topical glucocorticoids are the main treatment method, but treatment outcomes vary greatly among individuals, and patients with refractory EPDS need other treatment methods. EPDS generally requires long-term topical glucocorticoids, and adverse drug reactions are common. This review summarizes research progress in EPDS in recent years, in order to improve clinicians′ understanding of this disease.
