title: [A woman with an eschar].
abstract: A 65-year-old woman had an eschar after a holiday to Spain. A skin biopsy showed findings consistent with an ulcer but tested negative for fungi, atypical mycobacteria and Leishmania parasites. Rickettsia conorii serology was negative. The diagnosis necrotic arachnidism was made based on the clinical picture.
