Cutaneous asthenia in a Warmblood foal.

This research highlights a case of a 6-week-old Warmblood foal in Australia who was diagnosed with cutaneous asthenia (a skin condition characterized by hyperextensible skin and poor wound healing) after presenting multiple haematomas and abnormal scar formations. The study elaborates on the specifics related to the diagnosis and the similarities and differences with the hereditary equine regional dermal asthenia.

Clinical Presentation and Diagnosis

• The Warmblood foal in question was brought for examination due to multiple formations of haematomas in different locations on its body. The foal was also unable to heal wounds adequately and developed abnormal scar formations.
• These symptoms led to the diagnosis of cutaneous asthenia, a skin disorder characterized by skin hyperextensibility or the excessive elasticity of the skin, along with high tearability and abnormal scarring.
• The skin was hyperextensible and noted prolonged skin tenting which supports evidence of cutaneous asthenia. Despite additional histopathological and electron microscopic tests, the findings were inconclusive.

Euthanisation and Prognosis

• The severity and complications associated with the diagnosed condition led to the unfortunate decision of euthanising the foal, mainly due to the poor prognosis and compromised quality of life ahead.
• Prognosis for cases such as this is often bleak, given the extreme fragility of the skin and the complications arising from even minor injuries.

Importance of Case and Further Discussions

• This represented the first ever reported case of its kind in Australia involving a Warmblood horse breed. Thus making it unique and beneficial for further research and understanding within the equine veterinary community in Australia and globally.
• The presented case also sparks deeper discussions on cutaneous asthenia, particularly looking at its association with hereditary equine regional dermal asthenia (HERDA), a similar condition seen in certain equine breeds.
• While the exact relationship and differences between the two conditions remain to be fully understood, this case opens research avenues for in-depth study into these skin disorders among equines.
