Serous Adenofibroma of the Testicle

Testicular cancer represents the most common malignancy among males between 15 and 34 years of age. 1 Tumors of spermatogenic origin constitute to 95% of testicular neoplasms and are almost always malignant. Non-germ cell primary tumors, including those arising from supporting elements such as Sertoli and Leydig cells, are more often benign. Nonprimary tumors such as lymphoma, leukemia, and metastases can also manifest as testicular masses, usually in older individuals. 1 Rarely, primary testicular tumors resembling mullerian epithelial or stromal tumors of the ovary have been reported. 2-9 Here, we report the clinical, radiologic, and pathologic features of a testicular serous adenofibroma.
