A 6-year-old, intact male Jack Russell terrier was diagnosed with a mass in the caudal abdomen, and ultrasound revealed a large prostatic mass. A total-body computed tomography scan was performed for staging, and lung nodules were detected. Histological examination showed a proliferation of spindle cells arranged in interlacing fascicles. Immunohistochemical staining revealed cells were cytokeratin negative and immunoreactive for vimentin and α-smooth muscle actin; cells stained with desmin and S-100 were negative. A diagnosis of primary prostatic leiomyosarcoma with pulmonary metastases was made. This is one of the rare cases of primary prostatic mesenchymal tumor in the canine species.

Abstract
A 6-year-old, intact male Jack Russell terrier was diagnosed with a mass in the caudal abdomen, and ultrasound revealed a large prostatic mass. A total-body computed tomography scan was performed for staging, and lung nodules were detected. Histological examination showed a proliferation of spindle cells arranged in interlacing fascicles. Immunohistochemical staining revealed cells were cytokeratin negative and immunoreactive for vimentin and α-smooth muscle actin; cells stained with desmin and S-100 were negative. A diagnosis of primary prostatic leiomyosarcoma with pulmonary metastases was made. This is one of the rare cases of primary prostatic mesenchymal tumor in the canine species.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
