Erosive Pustular Dermatosis of the Scalp Following Herpes Zoster: Successful Treatment with Topical Tacrolimus

Abstract

Erosive pustular dermatosis of the scalp (EPDS) is a rare disorder of the elderly characterized by multiple pustular lesions with erosions and crusting that result in scarring alopecia. EPDS typically develops in aged or sun-damaged skin with a history of trauma. Histopathologically, EPDS is nonspecific, showing atrophic epidermis and chronic inflammation. Bacteriological and mycological investigations of EPDS are generally negative. Although herpes zoster is a common disorder in elderly people, previously reported cases of EPDS were rarely associated with herpes zoster. We present a rare case of EPDS following herpes zoster treated successfully with topical tacrolimus.
