Testicular microlithiasis (TM) is a rare condition characterized by the presence of multiple small intratesticular calcifications. The etiology is unknown but the condition has been observed in a variety of different urological conditions. We report on 5 cases diagnosed by ultrasonography at our departments from 1992 to 1994. A review of the literature plus our present 5 cases gives a total of 124 reported cases of TM. TM was associated with testicular malignancy in 44 patients (35%) of whom 24 (19%) had a seminoma and 20 (16%) a non-seminoma. There were 4 reports of testicular malignancy developing in patients with a prior diagnosis of TM. The condition should be considered premalignant and a careful follow-up of TM patients is advocated.
睾丸微石症（TM）是一种罕见病症，其特征为睾丸内存在多个小钙化灶。病因不明，但在多种不同的泌尿系统疾病中均观察到了这种情况。我们报告了1992年至1994年在我们科室通过超声诊断的5例病例。文献回顾加上我们目前的5例病例，共有124例报道的睾丸微石症病例。44例（35%）睾丸微石症患者与睾丸恶性肿瘤相关，其中24例（19%）患有精原细胞瘤，20例（16%）患有非精原细胞瘤。有4例报告显示，先前诊断为睾丸微石症的患者发生了睾丸恶性肿瘤。应将这种情况视为癌前病变，主张对睾丸微石症患者进行密切随访。
