例句
- To the best of our knowledge, the cyst reported here is the largest of the epidermoid cysts arising within the breast that have been reported.
值得一提的是在回顾相关文献后，此病例应是目前被报告发生于乳房内最大的类表皮囊肿。 - Although at times, the epidermoid cyst is difficult to distinguish from a malignant tumor, surgical excision is justified because of its potential for malignancy.
乳房的类表皮囊肿是少见的乳房良性疾病，但它有时于临床上不易与恶性肿瘤区分并且确有罕见的潜在恶性变化危险，所以手术切除是合适的治疗方式。
