A case of progressive facial hemiatrophy

Abstract

Progressive facial hemiatrophy (PFH) was first described by Parry and Romberg and this is a rare disorder of an unknown origin. PFH is characterized by slowly progressive, mostly unilateral facial atrophy of the skin, soft tissues, muscles and underlying bony structures and is usually develops in the first or second decade of life. Although the clinical presentation of PFH may appear similar to localized linear scleroderma en coup the sabre, some patients presenting with PFH have neither en coup the sabre nor generalized sclerosis. Herein, we report on an unusual case of a 7-year-old girl who presented with progressive hemiatrophy of the face.
