The paper describes a case of a long-lasting chronic migrant erythema (ME) in an 82-year-old female, which developed after the bite of an insect (a tick?). The specific feature of this case is an unusual duration (2 years) of a single focus of ME and autopsy of the skin revealed giant cells with centrally arranged 3-5 nuclei and cytoplam with PAS-positive inclusions as tiny (5 m) oblong formations, that may be Borelia.
