Leiomioma prostatico in un cane

We present a case report concerning a prostatic leiomyoma in a male intact dog with rectal and urinary tenesmus. Sonographic evaluation revealed a mass involving the right prostatic lobe. The mass was well-defined, hypoechoic and presented a dishomogeneous pattern. The diagnosis was made by ultrasound-guided tru-cut biopsy of the mass.
