Progressive Facial Hemiatrophy. (parry--romberg Syndrome). (a Case Report).

Progressive facial hemiatrophy or Parry-Romberg Syndrome is a rare disease characterized by atrophy in subcutaneous tissues on skin on one half of the face and some accompanied systematic findings. Generally, it develops before the age of 20. It is quite difficult to discriminate it from linear scleroderma localized in fronto-parietal area as they have similar clinical characteristics. In this article, 12-year-old case with atrophy on the left half of her face is presented. (Figure 1)
