Squamous cell carcinoma invading the right temporomandibular joint in a Belgian mare.

Abstract: This report describes a rare case of squamous cell carcinoma invading the right temporomandibular joint, right guttural pouch, and calvarium. Radiography, computed tomography, and histopathology were performed in the diagnostic workup. Computed tomography depicted more accurately than radiography the invasive nature, exact location, and extent of the lesion. Ce rapport décrit un rare cas de carcinomes squameux envahissant l’articulation temporomandibulaire droite, la poche gutturale et la calotte crânienne. Une radiographie, une tomodensitométrie et une histopathologie ont été réalisées dans le bilan diagnostique. La tomodensitométrie a dépeint plus fidèlement que la radiographie la nature invasive, l’emplacement exact et l’étendue de la lésion. (Traduit par Isabelle Vallières)

The research examines a unique instance of squamous cell carcinoma (a type of skin cancer) invading the right temporomandibular joint (a joint in the jaw), the right guttural pouch, and the skull in a Belgian mare. The study found that computed tomography (a type of imaging test) was more accurate than traditional radiography in identifying the precise location, severity, and invasive characteristics of the cancer.

Case Study Description

  • The report presents a rare case of squamous cell carcinoma, a form of skin cancer, extending to the right temporomandibular joint (a joint connecting the jawbone to the skull), the right guttural pouch (an air sac located in the horse’s head), and the calvarium (the upper dome-like portion of the skull).
  • The case involves a Belgian mare, a breed of draft horse, indicating that this research also contributes to veterinary medicine literature, particularly equine studies.

Diagnostic Methods

  • The diagnostic process involved radiography, computed tomography, and histopathology—a study of the microscopic structure of diseased tissue.
  • Radiography and computed tomography are both imaging tests used to visualise the internal structures of the body. Histopathology provides detailed information on the changes in tissues caused by the disease.
  • The researchers used these diverse methods to get a thorough understanding of the nature, location, and extent of the tumor.

Comparison of Radiography and Computed Tomography

  • The study found that computed tomography was a more accurate tool than radiography for showing the invasive nature of the tumor, pinpointing its exact location, and determining its overall size.
  • This finding is important because it suggests that computed tomography might be a more effective diagnostic tool for similar cases in the future.
  • Elucidating these differences in image-based diagnostics is valuable for both the advancement of equine medicine and may have potential applicability in a wider medical context.
