The condition can also affect other parts of the body, such as the teeth and nails. Treatment for focal dermal hypoplasia focuses on managing the symptoms and may include surgery, physical therapy, and other supportive care.
Types of Focal dermal hypoplasia
There are two main types of Focal Dermal Hypoplasia (FDH): classic and atypical.
In the classic type, individuals typically exhibit the characteristic signs of FDH, such as skin abnormalities, skeletal issues, and sometimes eye and dental problems. These symptoms usually involve the skin being thin and easily damaged, along with areas of pigmentation changes. Skeletal issues may include missing or extra fingers or toes, as well as misshapen bones in the hands and feet. Eye problems can range from mild issues like crossed eyes to more severe conditions such as cataracts or glaucoma. Additionally, dental abnormalities like missing teeth or malformed enamel may be present in individuals with classic FDH.
On the other hand, the atypical type of FDH is characterized by milder symptoms and a more variable presentation. While individuals with this type may still have some skin and skeletal abnormalities, they might not be as pronounced or widespread. Eye and dental issues are less common in atypical FDH compared to the classic type. The overall variability and less severe nature of symptoms in atypical FDH can make diagnosis and management more challenging, as the condition may not be as easily recognized based on clinical features alone.
