Plain-English summary
A 7-year-old neutered male ferret was brought in with two recurring masses near the anus that couldn't be completely removed due to their deep growth. After testing, the masses were found to be a type of cancer called apocrine adenocarcinoma. The ferret received localized radiation therapy, which worked well, shrinking the masses to the point they were no longer visible after six treatments. Unfortunately, he later developed fluid in his chest, which was linked to another type of cancer, and he passed away 71 days after his initial visit.

Abstract
A seven-year-old, neutered male ferret was referred to our hospital with two perianal masses (2.4x3.0 and 2.4x3.5 cm, respectively) that had recurred after initial surgical excision. Complete resection of the masses was impossible as there was deep invasion along the rectum. On histopathology, the masses were diagnosed as apocrine adenocarcinoma possibly of anal gland origin based on tumour location. There was marked response to localised radiotherapy using an orthovoltage unit at 4 Gy, twice weekly. No visible mass was detectable after six doses of radiation. However, at that time, pleural effusion was diagnosed and radiotherapy was discontinued. Cytology of a sample of the pleural effusion suggested mesothelioma, and no obvious pulmonary metastasis of anal sac adenocarcinoma were identified on thoracic radiography. The ferret died at home on day 71 after the first admission.
