A case of orf disease in a patient with scleroderma

EM: erythema multiforme INTRODUCTION Orf, also known as ecthyma contagiosum, contagious pustular dermatitis, infectious pustular dermatosis, ovine pustular dermatitis, and sore mouth, is a viral zoonotic disease resulting from the direct or indirect contact of damaged skin with infected animals. The virus is endemic in sheep and goats worldwide and manifests as an acute contagious skin condition that can cause substantial morbidity. The causative microorganism is the orf virus, an epitheliotropic DNA virus from the Parapoxvirus group. In humans, after a brief incubation period of 3 to 7 days, an orf lesion appears as a pruritic erythematous macule and then rises to form a papule. Lesions become nodular and vesicular and progress to a weeping target lesion that ulcerates and forms a dry crust. Herewe describe a case of orf disease in a patient with scleroderma.
