Cat-scratch disease lymphadenitis commonly develops in children. Feline contact by a scratch or bite causes Bartonella henselae infection. A papule develops in 3-5 days, followed by regional lymphadenopathy in 1-2 weeks. Some 12% of cases are complicated by attendant symptoms of fever, malaise, myalgia, and anorexia; encephalitis; oculoglandular disease; and severe systemic disease. By 2 months, symptoms usually resolve spontaneously.
