Epidermal (infundibular) and dermoid cysts in the dorsal midline of a three-year-old thoroughbred-cross gelding.
Abstract: Epidermal (infundibular) and dermoid cysts are unusual in the horse in contrast with other species. The diagnosis and treatment of six lesions in the dorsal midline of a three-year-old Thoroughbred-cross gelding is described. The lesions were believed to be congenital and presented asymptomatically but required attention because five of them were in the saddle region, thus preventing ridden exercise. Under general anaesthesia, the cysts were excised and subsequently examined histologically. The horse recovered uneventfully. This report is novel in that such midline cysts have not previously been described outside Australia and North America.

This research article describes the case of a three-year-old thoroughbred-cross gelding horse with unusual dermoid and epidermal cysts located in its midline, which needed treatment as they were affecting its ability to exercise. This is the first recorded case of such cysts being found in this species outside of Australia and North America.
Background and Case Description
- The horse presented in this case study was found to have six unusual cysts in its dorsal midline region. These particular types of cysts, known as epidermal (infundibular) and dermoid, are rare in horses compared to other species.
- The horse was three years old and of the thoroughbred-cross breed. Remarkably, the cysts were not causing any symptoms, but they did require treatment as five of the six were located in the saddle region, preventing the horse from being ridden.
- The cysts were believed to have been congenitally present in the horse, implying that they had been present since the horse’s birth.
Diagnosis and Treatment Procedure
- The research outlines the procedure that the veterinary team followed to treat the horse. Firstly, the horse was placed under general anesthesia.
- Once sedated, the cysts were surgically excised, or cut out, from the horse’s dorsal midline. The removed cysts were then sent to a laboratory for histological analysis, meaning the tissue was examined under a microscope for further investigation and to confirm the diagnosis.
- Post-surgery, the horse was reported to have recovered without complications.
Novelty and Significance of the Case
- The authors of this study highlight the novelty of this particular case. Although cysts of this kind have been observed in horses before, they haven’t been previously reported outside of Australia and North America.
- This therefore represents new geographical information about the presence of such collagenous cysts in horses, expanding our understanding of these cysts and where they may occur.
