Orf Infection on the Scalp of a Taiwanese Woman: A Case Report and Literature Review

Orf, or ecthyma contagiosum, is a zoonosis caused by Parapoxvirus that infects sheep and goats. Human transmission typically occurs in persons in contact with the infected animals or contaminated fomites and environment. In humans, it generally occurs as solitary or multiple skin lesions on the hands or fingers. Involvement of the head region has rarely been reported. We report an unusual case with multiple orf lesions on the scalp of a middle-aged woman, along with a review of previously reported Orf cases on the head region. Although Orf infection rarely happens on the head region, it should be considered in the differential diagnosis of cases with relevant animal exposure.
