Focal Dermal Hypoplasia
Major manifestations include areas of dermal hypoplasia through which nodules of adipose tissue herniate; angiofibromas around the mouth, vulva, and anus; dystrophy of the nails; and other skin, eye, dental, and skeletal abnormalities.Present at birth are areas of linear dermal hypoplasia (appearing as atrophied skin) and/or areas of complete absence of skin. The nodules of adipose tissue which herniate through the skin are yellowish-brown in color. Telangiectasia and hyperpigmentation (occasionally hypopigmentation) are frequently found. Angiofibromas appear as verrucous papules located around the mouth, vulva, and anus. They are usually red with a rough surface, are not well demarcated and may be mistaken for warts.
