Atypical histopathological findings in a 15‐year‐old Warmblood gelding diagnosed with anhidrosis in a temperate climate

Abstract

Summary This case report describes the atypical histopathological findings in a horse with anhidrosis that presented for evaluation of suspected respiratory disease during autumn/winter in a temperate climate. Anhidrosis in this horse was associated with mononuclear infiltration of T lymphocytes around sweat glands, a finding not previously reported in cases of equine anhidrosis. This report highlights the importance of considering anhidrosis as a differential diagnosis in the investigation of respiratory disease and illustrates that the condition can occur in horses residing in temperate climates.

“…However, some horses continue to demonstrate this clinical sign even in cool climates or when whole-body clipped [ 7 ]. Anhidrosis results when sweat glands become exhausted [ 104 ]. Anhidrosis can result in exercise intolerance and even death as thermoregulation is impaired [ 103 ].…”
