Tick-borne lymphadenopathy is infectious disease, an uncommon tick-borne rickettsiosis caused by Rickettsia slovaca. It is transmitted exclusively by the Dermacentor marginatus tick. It is endemic to parts of east and south Europe.[1]
Infection is associated with formation of an eschar at the site of the tick bite, constitutional symptoms (fever and pains), and lymphadenopathy chiefly affecting the neck. A maculopapular rash may sometimes also arise.
Presence of R. slovaca has been documented in Slovakia, Czechia, Ukraine, Russia, Armenia, Switzerland, France, Portugal, as well as others.[2]
Serologic evidence of infections has moreover been noted in Germany, Austria, and Lithuania.
