Eosinophilic pustulosis of the scalp in childhood.J Am Acad Dermatol. 1992 Jul; 27(1):55-60.JA
Among sterile pustulosis in childhood, a pruritic relapsing eosinophilic variant beginning in infancy and located mostly in the scalp was first described as eosinophilic pustular folliculitis in infancy by Lucky and colleagues in 1984.
Our purpose is to describe such a condition in five boys and one girl and comment on differential diagnosis and relation with Ofuji's disease.
This is a clinicopathologic study.
All patients had scalp pustules beginning in infancy or early childhood that were unresponsive to antibiotic therapy. Lesions also occurred on other areas but the scalp was the major site of involvement. Although secondary infection was demonstrated in one case, the lesions were primarily sterile. Smears of pustules showed a variable proportion of eosinophils. Histopathologic findings suggested a major role for eosinophils in this disorder because dermal eosinophilia was noted in all patients. The inflammatory pattern was not similar to Ofuji's disease. Transient blood eosinophilia was recorded in five patients. Topical steroids relieved inflammatory episodes. Dapsone was tried in one case with apparent benefit.
Eosinophilic pustulosis of the scalp in childhood is a self-limited disease that can be relieved by topical steroids.
