Genital lichen sclerosus associated with morphoea or systemic sclerosis: clinical and HLA characteristics

although patients with both morphoea and lichen sclerosus have been reporte d previously in the majority of these reports the lichen sclerosus has been extragenital. We report nine patients in whom genital lichen sclerosus coe xisted with scleroderma spectrum disorders including seven with morphoea, o ne with morphoea and lichen planus, and one with systemic sclerosis, The cl inical features, associated autoimmune disease, autoautibodies and HLA type are reported. Antibodies to Borrelia burgdorferi were not detected in any of the patients. The coexistence of these diseases raises a number of intri guing questions about the relationship between them.
