Scalp Eschar and Neck Lymphadenopathy Caused by Bartonella henselae after Tick Bite

Rickettsia slovaca and Rickettsia raoultii have been associated with a syndrome characterized by scalp eschar and neck lymphadenopathy following tick bites. However, in many cases, the causative agent remains undetermined. We report 3 cases of this syndrome caused by Bartonella henselae, and we propose the term SENLAT to collectively describe this clinical entity.
