An adult-onset generalized canine demodecosis is a life threatening form of demodecosis often seen in immunocompromised dogs. A generalized, adult-onset canine demodecosis with an unusual vascular invasion, thrombi and dissemination to peripheral, and visceral lymph nodes was diagnosed in an adult, female, American Bulldog of unknown age. Organized thrombi with intralesional mites were observed in multiple lymphatic vessels and in a section of blood vessel. Vascular invasion of mites with dissemination of mites into visceral lymph nodes, is an unusual findings not previously recorded in canine generalized demodecosis. Dissemination of mites to visceral lymph nodes through vascular channels may be part of the pathogenesis of chronic, untreated, and disseminated, adult-onset generalized canine demodecosis.
