Mechanobullous disease in two Belgian foals.

This research discusses a potential genetic skin disease, classified under a group known as epidermolysis bullosa (EB). The condition, which often results in blisters following minor injury, has been observed in two new-born Belgian foals. The paper describes the symptoms and pathological findings of this rarely seen condition, mostly identified in humans and domestic animals.

Epidermolysis Bullosa (EB)

• Epidermolysis bullosa (EB) is a group of inherited mechanobullous diseases, primarily known for causing blistering on skin after minor trauma.
• The common consequences of EB include secondary infection, scarring, alimentation issues from oral or internal injuries, and in severe cases, death.
• EB is categorised into three types—epidermolytic, dystrophic, or junctional, which are named according to the location of the epidermal-dermal separation.
• This disorder has to be carefully distinguished from more common bullous diseases of an autoimmune nature and from toxic epidermolytic diseases.

Occurrence and Classification of EB in Veterinary and Human Medicine

• EB is not a common disease in veterinary and human medicine.
• A lethal form of dystrophic EB has been reported in Suffolk and South Dorset Down sheep and Brangus calves.
• The epidermolytic type, also known as EB simplex, has been observed in collie dogs.

Disease in Belgian Foals

• The paper presents an investigation of an unusual case of a neonatal mechanobullous disease, potentially a type of EB, found in two Belgian foals.
• This purportedly hereditary condition is characterised by subepidermal cleft formation, with basement membrane material found adhered to the dermal surface of the cleft (a separation or gap in body tissue).
