A pony presented with a severe, chronic dermatitis around the ears, neck and trunk of the body, hind quarters and ventral abdomen. The pony was intensely pruritic as was an in-contact pony and both owners. A superficial skin scraping demonstrated multiple living mites, identified asSarcoptes scabiei. Equine pituitarypars intermediadysfunction (PPID) was diagnosed as an underlying, potentially immunosuppressive disorder. The pony was treated forSacroptes scabieias well as PPID and is doing well 2 months after initial presentation.
