Progressive hemifacial atrophy (Parry-Romberg syndrome) report with review of genetics and nosology.

We describe a boy with mild hemifacial atrophy (Parry-Romberg syndrome); he had localized scleroderma on a leg and his trunk, and antinuclear antibodies in his serum. These findings support suggestions that this disorder could be a variant of localized scleroderma rather than a developmental anomaly or dysplasia. A review of the literature does not support assertions of autosomal dominant inheritance of the condition.
