[Facial hemiatrophy, homolateral cervical linear scleroderma and thyroid disease]

A case of facial hemiatrophy and homolateral cervical band of scleroderma, complicated by hypothyroidism is reported. This case raises two problems: one is the problem of distinction between Romberg's disease and facial hemiatrophy due to a genuine localized scleroderma; the other concerns the relationship between localized scleroderma and dysthyroidism. The generalized scleroderma-dysthyroidism association has now been recognized, but the coexistence of thyroid disease and localized scleroderma has not yet been reported. Several pathogenetic hypotheses on this association are discussed.
