Synopsis

Parry-Romberg syndrome, also known as progressive facial hemiatrophy or idiopathic hemifacial atrophy, is thought to be a rare form of linear morphea presenting as slowly progressive deterioration of one half of the face. Hemiatrophy includes loss of subcutaneous tissue, muscle, and bone. Rare bilateral involvement has been reported. The tongue and salivary glands may be affected. Associated neurologic and ophthalmic involvement may include migraine headaches, seizures, trigeminal neuralgia, enophthalmos, and eyelid dysfunction.

Parry-Romberg syndrome typically develops in the first or second decade and is more common in females. It occurs spontaneously with no known preceding exposures or genetic predisposition. This syndrome is slowly progressive and can have an insidious onset. Initially, the asymmetry is subtle, noted first by the patient and caregivers only. Autoantibodies (antinuclear antibodies [ANA]) are detected in up to 50% of patients with this syndrome.
