Plain-English summary
A 2-year-old Standardbred gelding was brought in for a firm mass on the inside of his right front leg, which was causing him to limp more and more. The mass was found to be smooth and encapsulated, but due to the poor outlook for his future performance and the owner's financial limitations, the decision was made to euthanize him. After his passing, tests showed that the mass was a rare type of tumor called a perivascular wall tumor.

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.
