frequency of borrelia in morphea lesion by polymerase chain reaction in northeast of iran

results no borrelia dna was detected by pcr in skin lesions of patients with morphea. patients and methods sixty six patients with morphea were prospectively included in the present study. for each patient, formalin-fixed, paraffin-embedded tissue blocks of skin lesion biopsies were examined for borrelia spp. dna using pcr. objectives we aimed to find the frequency of borrelia in morphea lesions by polymerase chain reaction (pcr) in northeast of iran. background the etiology of morphea is still unknown. borrelia spp. as a causative agent of morphea has been discussed since 1985, but the relationship remains uncertain. conclusions the result of this study showed no relationship between borrelia infection and morphea lesions and in other word indicated that morphea, at least in iran, is not caused by borrelia spp.
