Parry-Romberg syndrome. Overlap with linear morphea

Abstract

Parry-Romberg syndrome, also known as progressive hemifacial atrophy, was first described by Parry in 1825 then Romberg in 1846. It is a poorly understood rare disorder characterized by progressive hemifacial atrophy of the skin, subcutaneous tissue, and sometimes, the underlying structures including muscles, cartilages and bones. A case report of a Saudi female with this rare disorder is presented with a brief review of the literature.
