Their incidence is reported to be 1.1\u20135.3% in dogs with prostatic disease. The aetiology of paraprostatic cysts is not fully understood, but they are believed to develop from the\n                      <jats:italic>uterus masculinus<\/jats:italic>\n                      .

A diagnosis of cystic\n                      <jats:italic>uterus masculinus<\/jats:italic>\n                      was made on the basis of the findings of abdominal ultrasonography and histopathology of tissues obtained during an exploratory laparotomy. In addition, a Sertoli cell tumour affecting both testes was diagnosed following scrotal castration. The cystic\n                      <jats:italic>uterus masculinus<\/jats:italic>\n                      was completely resected, after which the tenesmus and bloody discharge resolved.
