EtiopathogenesisThis section has been translated automatically.
mutation of the COL7A1 gene mapped on chromosome 3p21.3. The mutation leads to reduced or absent synthesis of collagen type VII.
Animal experiments in collagen type VII-deficient mice showed that they produce the protein cochlin in a reduced way. This in turn leads to increased bacterial colonisation of wounds.
ManifestationThis section has been translated automatically.
In children, usually after the age of 5.
Clinical featuresThis section has been translated automatically.
Image of the epidermolysis bullosa dystrophica dominans. Additionally perifollicular, ivory-coloured, flat to lenticular, partly confluent papules, especially in the lumbosacral region or at the acra. These are very typical for the clinical picture. Hardly any mucosa or tooth damage.
HistologyThis section has been translated automatically.
- Subepidermal blistering.
- Electron microscopic: Dermolytic blistering below the lamina densa. Reduced number of normal or rudimentary anchoring fibrils.
Differential diagnosisThis section has been translated automatically.
External therapyThis section has been translated automatically.
- Antiseptic solution such as octenidine (e.g. Octenisept), quinolinol solution(e.g. Chinosol 1:1000), R042 or potassium permanganate solution(light pink) to prevent secondary infections.
- Avoidance of mechanical irritations and pressure points on the skin, diet rich in vitamins and minerals.
Internal therapyThis section has been translated automatically.
Successes with high-dose glucocorticoid pulse therapy(100-150 mg/day prednisolone) have been described. Treatment is generally cautious, as blister formation decreases continuously and disappears within the first years of life.
