Testicular microlithiasis (TM) is an unusual ultrasonographic manifestation in testicular parenchyma. Limited information is available about TM in Taiwanese men. We performed a retrospective analysis to investigate the characteristics of TM and its association with testicular cancer and infertility in Taiwan. Male patients who had received scrotal ultrasonography because of scrotal symptoms or infertility between January 2000 and December 2003 were recruited. The incidence of TM was 7.6%. Both testicular microlithiasis and testicular cancer occurred chiefly in the third decade. Patients with TM exhibit a higher chance of testicular cancer (6% vs. 0.9%). No local field effect between TM and testicular cancer was observed. Testicular microlithiasis severity is not positively correlated with sperm quality and sterility. Forty-eight patients (32%) were available at follow-up. No patient developed a testicular tumor or elevated tumor markers (AFP, beta-hCG) during follow-up. We suggest monthly self-examination, annual scrotal ultrasonography and tumor markers screening between the age of 20 and 30 years of patients with TM.
睾丸微石症（TM）是睾丸实质内一种不常见的超声表现。关于台湾男性睾丸微石症的信息有限。我们进行了一项回顾性分析，以研究台湾地区睾丸微石症的特征及其与睾丸癌和不育症的关联。招募了2000年1月至2003年12月期间因阴囊症状或不育症接受阴囊超声检查的男性患者。睾丸微石症的发生率为7.6%。睾丸微石症和睾丸癌主要发生在第三个十年。患有睾丸微石症的患者患睾丸癌的几率更高（6%对0.9%）。未观察到睾丸微石症与睾丸癌之间的局部场效应。睾丸微石症的严重程度与精子质量和不育症无正相关。48例患者（32%）进行了随访。随访期间没有患者发生睾丸肿瘤或肿瘤标志物（甲胎蛋白、β-人绒毛膜促性腺激素）升高。我们建议对患有睾丸微石症的患者在20至30岁之间进行每月一次的自我检查、每年一次的阴囊超声检查和肿瘤标志物筛查。
