Milker's nodule - Case report

Milker's nodule (noduli mulgentium) is a benign viral skin disease caused by parapoxvirus, a poxvirus that is endemic in cattle. The virus is usually transmitted to cattle handlers from infected cows. We present a case of a 25-year-old housewife who milked cows on her family farm and developed itchy, purplish red nodules on her fingers and hands, and lymphangiitis of the right arm. Two weeks before, several cows on her family farm were treated by a veterinarian under the diagnosis of pseudocowpox. She was treated with orally administered amoxicillin with clavulanic acid 2 g for 10 days, with complete resolution of lymphangiitis. The nodules resolved in several weeks.
