Actinomycosis of the mandible, mimicking a malignancy in a horse.
Abstract: Osteomyelitis of the mandible with Actinomyces species was diagnosed in a 4-year-old sports horse with radiographic changes suggestive of neoplasia. Surgical debridement, intravenous and local iodine solution treatment were administered. Mandibular Actinomyces infections are reported in humans and ruminants; they have not been previously reported in the horse. Actinomycose de la mandibule simulant une malignité chez un cheval. Une ostéomyélite de la mandibule à Actinomyces sp. a été diagnostiquée chez un cheval de sport âgé de 4 ans montrant des changements radiographiques ressemblant à une néoplasie. Le débridement chirurgical, un traitement intraveineux et local avec une solution d’iode ont été administrés. Les infections mandibulaires à Actinomyces sont rapportées chez les humains et les ruminants mais pas encore chez les chevaux. (Traduit par Docteur André Blouin)

The research study discusses a unique case of osteomyelitis in a 4-year-old sports horse, caused by Actinomyces species, which initially seemed to be a neoplastic condition as per X-ray indications. This previously unreported occurrence of mandibular Actinomyces infections in horses was treated through surgical cleaning, along with intravenous and local iodine solution.
About the Study
- The study presents a unique case of osteomyelitis (an infection in the bone) in a 4-year-old sports horse, which was caused by Actinomyces species.
- Actinomycosis is a rare infectious bacterial disease, mostly affecting the face and neck. It’s more commonly reported in humans and ruminants (cud-chewing animals).
- In the case of the horse in this study, the X-ray of the horse indicated signs of neoplasia, which means abnormal new tissue growth often referring to cancer. However, it was revealed to be an infection, not a neoplastic condition as initially suspected.
Treatment Administered
- The horse was given a treatment involving surgical debridement, which is a surgical procedure to remove infected, damaged tissue and foreign objects from a wound.
- Intravenous therapy and local iodine solution were used to counter the infection.
- The combination of the treatments aimed at removing the infection from the horse’s mandible and prevent further spread or complications.
Significance of the Study
- This study contributes significantly to veterinary medicine by documenting this rare infection in horses, which had previously not been reported.
- By studying this case and the successful treatment administered, veterinarians can be guided on how to identify similar conditions and approach the treatment in the future.
