Plain-English summary
A 24-year-old male Solomon Island eclectus parrot was found to have a mass in his abdomen during a routine check-up. Tests suggested it was a testicular tumor, and the vet started treatment with hormone therapy and chemotherapy, which significantly reduced the size of the tumor. Afterward, the parrot underwent surgery to remove the remaining tumor. Seven months later, follow-up scans showed no signs of the tumor returning, marking a successful outcome for this treatment approach.

Abstract
An intracoelomic mass was palpated on an annual exam of a 24-year-old male Solomon Island eclectus parrot (). The initial diagnostic workup included a complete blood count, plasma biochemistry panel, and coelomic ultrasound. Computed tomography was highly suggestive of a testicular mass. Tamoxifen and the gonadotropin-releasing hormone agonists leuprolide and deslorelin were administered as neoadjunctive endocrine therapies. Biopsy and histologic examination confirmed a testicular mass consistent with a round cell tumor. Four doses of carboplatin 15 mg/kg IV were administered as neoadjunctive chemotherapy, and testicular size decreased by approximately 95%. The remaining gross tumor was removed via orchidectomy with clean but narrow margins. Seven months following surgery, a contrast CT scan did not show any evidence of recurrence of or metastasis from the original mass. This is the first report of successful treatment of a testicular tumor in a psittacine with neoadjuvant chemotherapy and orchidectomy.
