Progressive facial hemiatrophy (Parry-Romberg syndrome).

Three cases of progressive facial hemiatrophy are presented. In all three cases there is evidence of localised scleroderma or morphea in association with the facial hemiatrophy.

In two cases, ocular complications are prominent and in one Raynaud's phenomena provide clear asymmetrical dilatation of the lateral ventricle suggest that there may be a central rather than a peripheral cause for the sympathetic overactivity.
