[Ixodes tick-borne borreliosis with erythema nodosum].

Ixodes tick-borne borrelioses (ITBB) is a group of natural-and-focal transmissible infections caused by Borrelia burgdorferi and characterized by multiple organ dysfunctions and a chronic progressive course. The pathognomonic marker of an acute period of the disease is migratory erythema at the site of tick suction. There may be other skin symptoms: rash on the face, urticaria, transient pointed and minor eruptions. Diagnosis presents some certain difficulties in these cases. The paper gives a description of rare eruptions in ITBB.
