Chronologic Presentation of a Severe Case of Progressive Hemifacial Atrophy (Parry-Romberg Syndrome) with the Loss of an Eye

Progressive hemifacial atrophy, also known as Parry-Romberg syndrome, is a slowly advancing degenerative disease that mostly affects the cutaneous, subcutaneous fatty tissue, muscle tissue, and bone structures on one side of the face. We describe the chronological progression of this very rare syndrome from early childhood until adulthood in a patient who developed severe atrophy and lost one eye. We also discuss the aetiology and pathophysiology of this syndrome.
