ASSOCIATION OF LICHEN-SCLEROSUS AND LINEA R SCLERODERMA ON A SOME LIMB

Introduction. Coexistence of lichen sclerosus and scleroderma is well demonstrated. However, clinical and histological lesions of lichen scl erosus and scleroderma, in a linear pattern, do not seem to have been reported. Case report. We report the case in a six years old boy, of b oth lichen sclerosus and linear scleroderma lesion that involved his l eft lower limb. Immunological and inflammatory investigation was norma l or negative, as well as, bone and muscles analyze of the leg. Furthe r outcome was benign. Discussion. This new case confirms the possibili ty of an association, inside a same limb, of lichen sclerosus and loca lized scleroderma, and supports the concept of a common etiological pr ocess in these two diseases. In an other hand, it could reflect the po ssibility of two distinct clinical expressions of the same pathogenic process.
