L’épidermolyse bulleuse jonctionnelle (EBJ) est une maladie génétique létale qui concerne particulièrement les Comtois et les Breton. L’épidermolyse bulleuse (EB) comprend un groupe hétérogène de génodermatoses dont le pronostic est variable. Le diagnostic peut être évoqué en anténatal.

Epidermolyae definition Epidermolysis bullosa simplex EBS is a group of hereditary bullleuse bullosa HEB disorders characterized by skin fragility resulting in intraepidermal blisters and erosions that occur either spontaneously or after physical trauma.
Epidermolysis bullosa acquisita EBA is a rare autoimmune subepidermal bullous disease with autoimmunity to the type VII collagen which is the major component of anchoring fibrils.
Other search option s Alphabetical list. Diagnostic methods Diagnosis is based on determination of the epidermal level within which blisters develop following minor skin traction.
A 3-year-old boy presented symmetrical lesions bklleuse the anterior aspect of the knees since starting to walk.

Patients with EB subtypes with the highest risk of specific extracutaneous complications need to be monitored closely and appropriate measures implemented to prevent the affected tissues from becoming severely injured.

Prenatal testing using fetal DNA from chorionic villi or amniotic fluid cells is possible if the causative gene is known and the pathogenetic mutation s identified.
Optical microscopy, electron microscopy and immunofluorescence analysis suggested dystrophic epidermolysis bullosa.
The diagnosis is suggested by prenatal ultrasound at signs, especially for junctional EB with pyloric atresia. Access to the PDF text. We describe a case of de novo dominant inherited dystrophic epidermolysis bullosa localised strictly to the knees. Correct diagnosis of EBS subtype bullfuse crucial to proper genetic counseling.

However, in the neonatal period, in utero herpes simplex infection may be considered, especially if there is no family history of blistering disease or if clinical findings are atypical for EB.
Recommended techniques are immunofluorescence antigen mapping IFM and transmission electron microscopy TEM performed on a skin biopsy sample. No nail, epidermllyse or mucous dystrophy was observed and the parents presented no clinical abnormalities. Management and treatment Management is based on the avoidance of blistering by meticulous protective skin padding and appropriate life-style to avoid trauma, and prevention of secondary infection by careful wound care.

Dystrophic epidermolysis bullosa may present in generalized or localized forms and the disease may be inherited in either autosomal dominant or recessive mode. In the dominant forms, and more recently in recessive cases, glycine substitutions have been implicated, although the precise role of glycine substitution has yet to be clarified.
