Background:
Dystrophic epidermolysis bullosa is characterized by fragile ulcerations of the skin caused by mutations in specific genes. However, genetic typing of this condition is rare.
Case Summary:
An 11-year-old female suffered from recurrent fever, visible ulcerations of the entire skin, and severe malnutrition. Genetic testing revealed a frameshift mutation in the coding region 4047 of the 35th intron region of COL7A1, and she was diagnosed as malnutrition-type epidermolysis bullosa. Drug therapy (immunoglobulin, fresh frozen plasma), topical therapy (silver ion dressing), fever reduction, cough relief, and promotion of gastrointestinal peristalsis are mainly used for respiratory and gastrointestinal complications. The patient's condition improved after treatment.
Conclusion:
Dystrophic epidermolysis bullosa caused by a new framework shift mutation in COL7A1 should be taken seriously.
