Testicular fibroma: A case report and literature review.

Sex cord-stromal tumors are the second most common testicular tumors after germ cell tumors. They account for about 2%-5% of adult testicular tumors. Most of these tumors are benign. The most common sex cord-stromal tumor is Leydig cell tumor. In contrast, testicular fibroma is a very rare type of sex cord-stromal tumors. Histologically, testicular fibromas resemble their ovarian counterparts; however, they are much less common than ovarian fibromas. To the best of our knowledge, <50 cases of testicular fibromas are reported in the English literature. Herein, we report a rare case of testicular fibroma with acellular collagen plaque in a 51-year-old male presenting as a painless testicular mass.
