General Discussion

Parry-Romberg syndrome is a rare, acquired disorder characterized by slowly progressive shrinkage (atrophy) of the skin and soft tissues of half of the face (hemifacial atrophy). In rare cases, both sides of the face are affected. In some cases, atrophy may also affect the limbs usually on the same side of the body as the facial atrophy. The severity and specific symptoms of Parry-Romberg syndrome are highly variable from one person to another. Additional symptoms can potentially develop in some people including neurological abnormalities or abnormalities affecting the eyes or teeth. Parry-Romberg syndrome usually becomes apparent during the first decade of life or early during the second decade but does occur in adulthood. The majority of individuals with Parry-Romberg syndrome experience symptoms before the age of 20 years. The exact cause of Parry-Romberg syndrome is unknown; cases appear to occur randomly for unknown reasons (sporadically).
