Abstract:
Ehlers-Danlos syndrome (EDS) is a rare genetic disorder in dogs and cats and has been mostly reported in purebred cats. In this study, we report a case of a 1-year-old castrated male Korean shorthair cat, who presented with multiple small skin tears and bruises distributed over the entire trunk area. The cat’s skin was hyperextensible and easily torn with gentle touch. The skin extensibility index of the cat was 25%, indicating the possibility of EDS. The cat exhibited no signs of pruritus or inflammation, and no underlying disease was found.However, radiography revealed hip joint subluxation and arthritis. Following this, biopsy of the lacerated skin was performed. Histopathological examination of the skin revealed that in the dermis adjacent to the lesions, the collagen fibers were irregular in size and width, with a slightly thinner epidermis, and increased interfibrillar spaces containing low numbers of scattered well-differentiated fibroblasts and mast cells. Histopathological examination of the skin confirmed EDS. The symptoms observed in the cat, including skin hyperextensibility, multiple bruising, hip joint subluxation, and arthritis, corresponded to the classical subtype of EDS in humans. Thus, this study is a rare report of a classical EDS case in a Korean shorthair cat. This study suggests that skin extensibility index and biopsy are useful diagnostic procedures for confirming EDS in animals until a more definitive genetic test is established.
