Plain-English summary
A 16-year-old female Japanese cat was brought to the vet because of a lump on her mammary gland that was about 3 cm wide. Tests revealed that the lump was caused by an infection with Toxoplasma gondii, a type of parasite. This condition, known as cutaneous toxoplasmosis, was confirmed through various laboratory tests. While the cat's treatment details were not specified, identifying the infection is crucial for determining the right care. If your cat has unusual lumps or skin issues, it's important to consult your veterinarian for proper diagnosis and treatment.

Abstract
A 16-year-old female Japanese cat was presented with a single mammary-gland nodule approximately 3 cm in diameter. Histologically, the nodule consisted of necrotizing granulomatous panniculitis, vasculitis, and mastitis, and contained free and clustered protozoal organisms. The organism was present in the cytoplasm of macrophages, fibroblasts, endothelial cells, and mammary-gland epithelia. The organism was positive for anti- Toxoplasma gondii and anti- Neospora caninum antibodies. Electron microscopy showed single and grouped tachyzoites, with morphologic features similar to those of T. gondii. Polymerase chain reaction and deoxyribonucleic acid sequence analysis was consistent with T. gondii infection. This is the first report of cutaneous toxoplasmosis in a Japanese cat.
