An axial CT scan of a 17-year-old girl with Parry–Romberg syndrome, showing severe loss of subcutaneous tissue and muscle of the right side of the face, with no apparent involvement of the facial bones

Parry–Romberg syndrome (also known as progressive hemifacial atrophy) is a rare disease characterized by progressive shrinkage and degeneration of the tissues beneath the skin, usually on only one side of the face (hemifacial atrophy) but occasionally extending to other parts of the body. An autoimmune mechanism is suspected, and the syndrome may be a variant of localized scleroderma, but the precise etiology and pathogenesis of this acquired disorder remains unknown. It has been reported in the literature as a possible consequence of sympathectomy. The syndrome has a higher prevalence in females and typically appears between 5 –15 years of age.
