lichen sclerosus et atrophicus/proline

Although frequently linked clinically with autoimmune disease, no immunogenetic basis for lichen sclerosus has ever been established. In this study, we examined in detail the HLA antigens of 84 patients with histologically proven disease, compared with 357 controls. Patients with lichen sclerosus

Hydroxyproline, hydroxylysine and proline were determined on skin from 18 patients with localized scleroderma (10 with localized morphoea plaque and 8 with generalized morphoea). Three skin biopsies (4mm punch) were obtained from each patient: One from the center of a sclerotic plaque, one from the
