Regional lymphadenopathy develops within 2 wk, usually unilaterally and in relation to the scratch site. The nodes are initially firm and tender, later becoming fluctuant, and may drain with fistula formation. The skin lesion and lymphadenopathy subside spontaneously within 2 to 5 mo. Complete recovery is usual. Treatment is local head application, analgesics and antibiotics.
Prognosis is excellent.
