A self-limited acute febrile sterile neutrophilic dermatosis (Sweet's-like syndrome) in a dog featuring target skin lesions with strong upregulation of interleukin-8 and T-helper 1 pathway.

In this report, we provide a case of self-limiting canine acute febrile sterile neutrophilic dermatosis in which the clinical signs featured typical target skin lesions with strong upregulation of T-helper 1 markers and interleukin-8, a potent neutrophil chemoattractant. Further, large case series are needed to characterize canine sterile neutrophilic dermatosis.
