Dear editor, Parry Romberg syndrome (PRS), also known as progressive hemifacial atrophy, is a rare craniofacial disorder characterized by unilateral facial atrophy affecting the skin, subcutis, muscle, and bones.1 PRS is considered a severe variant of linear morphea, sharing some features with en coup de sabre scleroderma.
