Plain-English summary
A 6-year-old neutered male British Shorthair cat was brought in with two quickly growing lumps on his chest. Tests confirmed he had high-grade non-Hodgkin's lymphoma, a type of cancer. Surprisingly, after a biopsy, the lumps shrank on their own without any treatment. Unfortunately, the cat had a relapse three months later and did not respond well to further treatment, leading to the difficult decision of euthanasia.

Abstract
CASE REPORT: A 6-year-old neutered male British Shorthair cat presented with two rapidly growing subcutaneous masses, one over each thoracic wall. High-grade, non-Hodgkin's lymphoma was confirmed following histopathology, immunohistochemistry and PCR analysis for antigen receptor re-arrangements. Following biopsy there was rapid regression of the remaining neoplastic tissue with no medical treatment. The cat relapsed 3 months later, with poor response to therapy, and was euthanased. CONCLUSION: Spontaneous regression (SR) of cancer is a rare occurrence and is uncommonly reported in veterinary species. To the author's knowledge this is the first reported case of SR of non-FeLV-related feline, high-grade non-Hodgkin's lymphoma.
