Plain-English summary
An 18-month-old male basset hound was brought to the vet because he was vomiting, had diarrhea, and seemed depressed. An ultrasound showed a mass in his left kidney, and after monitoring it for six months, the vet decided to remove the kidney. The mass was diagnosed as a congenital mesoblastic nephroma, a type of tumor that is generally benign. After surgery, the dog was followed up for two and a half years and remained healthy, showing that the treatment was successful.

Abstract
An 18-month-old male basset hound was presented with vomiting, diarrhoea and depression. Abdominal ultrasonography revealed a mass in the left kidney. An ultrasound-guided core-biopsy indicated aggregates of spindle cells, but did not allow a definitive diagnosis. Nephrectomy was performed after a period of six months, when ultrasound examination revealed a slight increase in mass dimensions. Histologically the mass was composed of neoplastic spindle cells forming interlacing fascicles, bundles and whorls, within a loose myxoid to dense collagenous stroma. Immunohistochemically neoplastic cells were positive for vimentin and smooth muscle actin. Based on these findings the tumour was diagnosed as a congenital mesoblastic nephroma, classical variant. After a two-and-a-half-year follow-up the dog was clinically healthy, indicating a benign behaviour. To the authors' knowledge, this report describes the first case of canine congenital mesoblastic nephroma successfully treated surgically, with a reasonable postsurgical follow-up.
