ICD-10 online (WHO version 2019) |
The dominant EBD (DDEB) or generalized dominant EBD (DDEB-gene) is a very rare form of epidermolysis bullosa dystrophica (EBD) with the main features of generalized blistering, milia , atrophic scars and dystrophy of the nails .
Synonyms are: Epidermolysis bullosa dystrophica albopapuloidea; EB dystrophica albopapuloidea Pasini; EB hereditaria dystrophica Pasini; Epidermolysis bullosa, dystrophic, autosomal dominant, Pasini type; Latin Dystrophia cutis spinalis congenita
The previous division into
- Epidermolysis bullosa, dystrophic, autosomal dominant, Pasini type
- Epidermolysis bullosa, dystrophic, autosomal dominant, Cockayne-Touraine type
Is no longer in use.
The names refer to the author of the first description from 1928 by the Italian dermatologist Agostino Pasini . and reports from 1933 by the English doctor Edward Alfred Cockayne and from 1942 by the French dermatologist Albert Touraine .
distribution
It is inherited in an autosomal dominant manner ; the frequency of this most common form of autosomal dominant EBD is not known.
root cause
Of the disease are mutations in the COL7A1 - gene on chromosome 3 locus p21.31 based encoding which VII for the type of collagen.
Clinical manifestations
Clinical criteria are:
- Manifestation at birth with blistering of the extremities
- Healing with scarring
- Always nail dystrophy , possibly with nail loss
- ivory-colored papules and plaques (albopapuloid lesions) mostly on the trunk
- Possibly aplasia cutis congenita on the lower legs
- Less often blisters in the mucous membrane
diagnosis
The diagnosis results from the clinical examination and is confirmed by immunofluorescence antigen mapping and / or transmission electron microscopy . Prenatal evidence can be provided by human genetic testing .
Differential diagnosis
Other forms of the epidermolysis bullosa group are also to be distinguished
- Aplasia cutis congenita
- Herpes simplex infection
- Bullous pemphigoid
- Impetigo contagiosa
- Incontinentia pigmenti
therapy
Treatment is symptomatic.
