Plain-English summary
A nine-year-old male Giant Schnauzer was brought in for evaluation of a rapidly growing, non-painful mass on his left shoulder, which was diagnosed as malignant fibrosarcoma. To assess the tumor's characteristics and response to treatment, the vet used a special imaging technique called scintigraphy. This showed the tumor's size and blood supply, confirming its aggressive nature. The dog then received external radiation therapy to shrink the tumor before surgery. After treatment, the tumor was surgically removed, ensuring all cancerous tissue was excised. The imaging technique proved helpful in guiding the treatment process.

Abstract
A nine-year-old male black Giant Schnauzer dog was referred for the scintigraphic evaluation with a history of malignant fibrosarcoma with a rapidly growing non painful mass on the left shoulder region quite near to the site of an operation performed four months ago. We carried out oncological scintigraphy using pentavalent (99m)Technetium labelled dimercaptosuccinic acid [(99m)Tc(V)-DMSA], a tumour localising radiopharmaceutical agent. The study was performed to assess the margins, vascularity of the tumour and response to the cancer therapy. Uniform intense radiopharmaceutical uptake was observed in the lesion indicating its margins, vascularity and malignant nature. The dog was subjected to external radiation therapy to control the growth of the cancer and to bring the tumour mass to an operable size. The dog was followed up with (99m)Tc(V)-DMSA scintigraphy pre-irradiation and post-irradiation. Immediately after the post-irradiation scintigraphy, the dog was operated on. During the surgery, resection of the tumour margins was performed carefully using a hand held gamma probe to assure that no tumour tissue was left inside. In conclusion, the authors would like to state that (99m)Tc(V)-DMSA oncoscintigraphy is valuable in the assessment and evaluation of therapy in canine soft tissue cancer.
