Canine testicular tumors in descended and cryptorchid testes.
A comparative study of canine testicular tumors in descended and cryptorchid testes was performed in order to associate pathologic features with clinical signs. Observation on 80 canine testicular tumors revealed the following distribution: in undescended testes, 4 tumors were classified as Seminomas (mean age: 8.8 +/- 3 years) and 14 as Sertoli cell tumors (8.7 +/- 1.7 years); in descended testes, 21 tumors were classified as seminomas (8.8 +/- 3 years), 13 as Sertoli cell tumors (9.8 +/- 1.8 years), 22 as Leydig cell tumors (11.5 +/- 2 years), 5 multiple primary tumors and 1 as an immunoblastic lymphoma. Histological features were studied and correlated with other clinical parameters: feminization manifestations, prostatic disease, perineal hernia and perianal gland tumor.
