Equine sinonasal anaplastic sarcoma infected with multi-drug resistant Escherichia coli.
Abstract: A 5-year-old Hanoverian horse was presented for a palpable and visible mass over the frontal and maxillary sinuses. Following endoscopy and radiography surgical excision was attempted. The horse was euthanized during surgery and samples of the mass were identified as malignant anaplastic sarcoma, a seldom reported sinonasal tumor in equids. Sarcome anaplasique naso-sinusien équin infecté par Escherichia coli multirésistant aux antibiotiques. Un cheval Hanovrien âgé de 5 ans a été présenté pour une masse palpable et visible sur les sinus frontal et maxillaire. Après une endoscopie et la radiographie, une excision chirurgicale a été tentée. Le cheval a été euthanasié durant la chirurgie et des échantillons de la masse ont été identifiés comme un sarcome anaplasique malin, une tumeur naso-sinusienne rarement signalée chez les équidés.(Traduit par Isabelle Vallières).

This research conducted an investigation into a unique case where a 5-year-old Hanoverian horse was found to have a rare sinonasal tumor, known as malignant anaplastic sarcoma. Despite an attempt to surgically remove the tumor, the horse was euthanized mid-surgery and the tumor samples taken were confirmed to be anaplastic sarcoma.
Identification and Diagnosis
- The investigation process began when the Hanoverian horse was presented to the researchers with a palpable and visible mass over the horse’s frontal and maxillary sinuses.
- The team then carried out an endoscopy and radiography of this mass, to identify what it could be and decide on the best course of action.
Surgical Intervention
- Following these diagnostic methods, the decision was made to attempt surgical excision of the mass. This meant that the horse underwent a procedure to have the mass removed.
- In the course of the surgery, however, it was decided to euthanize the horse, as it was found that the tumor was malignant and thus highly aggressive and difficult to manage effectively through surgery.
Post-Mortem Analysis
- With the horse euthanized, samples were taken from the mass for further testing and analysis to understand the type and nature of the tumor.
- The results showed the mass to be anaplastic sarcoma, a rarely reported tumor in the sinonasal area of horses.
- This provided valuable insight into this particular kind of rare tumor, and means that in future similar cases, veterinarians might be able to diagnose and potentially treat it based on the findings from this case.
