Perivascular wall tumour presenting as pastern mass in a Standardbred gelding.

Abstract: A 2-year-old Standardbred gelding was referred for a mass on the palmaromedial right front pastern which was accompanied by progressively worsening lameness. The mass was firm to palpation and covered by normal skin. Ultrasonographically, a smooth encapsulated mass was present, medial to the flexor tendons and palmar to the neurovascular bundle. Because of a poor prognosis for future athletic performance without surgical or chemotherapeutic intervention and economic constraints preventing further diagnostics and treatment, the horse was euthanised. Post-mortem magnetic resonance imaging, histopathology and immunohistochemistry revealed the mass to be a perivascular wall tumour, the first record of such a neoplasia in the horse.

The research paper discusses a case of a perivascular wall tumor found in a 2-year-old male horse, which manifested as a mass in the pastern region of the horse’s foot, causing severe lameness. This is the first recorded case of such a type of tumor in a horse.

Presentation of Case

  • The study revolves around a 2-year-old Standardbred gelding, which is a breed of horse commonly used in harness racing. The horse was referred to the researchers due to a mass that was observed on the right front pastern, an area of a horse’s foot. This mass was causing the horse to exhibit worsening lameness, or difficulty in moving.
  • On examination, the mass was found to be firm, but was covered by normal skin. Using ultrasonography, the mass was seen to be well-encapsulated, or fully enclosed within a protective layer, and was located medial to the flexor tendons, indicating it was to the inside, and palmar to the neurovascular bundle, signifying it was towards the lower side.

Diagnosis and Outcome

  • Given the horse’s likely diminishing athletic performance, poor prognosis without interventions such as surgery or chemotherapy, and considering the financial constraints in pursuing further diagnostic and treatment procedures, the decision was made to euthanise the horse.
  • Post-mortem evaluations were conducted using magnetic resonance imaging (MRI), histopathology and immunohistochemistry techniques to identify the nature of the mass. This revealed that the mass was a perivascular wall tumor. Perivascular wall tumors are rare tumors that grow from the walls of blood vessels.
  • The discovery marked the first ever record of a perivascular wall tumor occurring in a horse. This finding could add valuable knowledge to the veterinary field and could help in the identification and treatment of similar cases in the future.
