Within 1-3 weeks, lymphadenopathy develops in a single node or group of regional nodes draining the inoculation site. Single node involvement occurs in more than one half of patients. More than 65% of cases involve the nodes in the axillae or anterior or posterior triangles of the neck. Inguinal lymphadenopathy has been reported in 17% of cases.
