Plain-English summary
An 11-year-old male Miniature Dachshund was brought to the vet because he was having trouble passing stool. After further examination, including a CT scan, a mass was found in his prostate. The dog underwent surgery to remove the prostate and testicles about two weeks later. The mass was identified as a prostatic stromal tumor, which means it had uncertain potential to be cancerous. Fortunately, the surgery was performed, and the dog was treated, but ongoing monitoring will be necessary to watch for any changes.

Abstract
An 11-year-old male Miniature Dachshund dog was presented with dyschezia. Computed tomography examination 35 days after the initial visit revealed a prostate mass (4.0 × 3.5 × 2.7 cm) and prostatectomy and orchiectomy were performed 13 days later. Grossly, the prostate was rubbery and the cut surface of the mass was swollen. The mass was whitish and demarcated from the surrounding tissues. Microscopically, the mass had a capsulate consisting of atypical spindloid stromal cells arranged in a phyllode pattern and also in a fasciculated pattern admixed with acinar ductal cells. Atypical stromal cells contained round-to-oval finely hyperchromatic nuclei that had distinct nuclei and abundant eosinophilic cytoplasm. Immunohistochemically, the atypical stromal cells were positive for vimentin, CD34, desmin, α-smooth muscle actin, progesterone receptor and androgen receptor but negative for cytokeratin AE1/AE3, p63, c-Kit, DOG-1 and SOX10. On the basis of these findings, the tumour was diagnosed as a prostatic stromal tumour of uncertain malignant potential.
