A 50-year-old Japanese man with a two-year history of a painless right scrotal mass visited our hospital. Considering laboratory findings and computed tomography, the patient was diagnosed with an uncharacteristic testicular tumor. No metastases were present on radiographic study at the first visit. Emergent high radical orchiectomy was performed, and the tumor was identified as a squamous cell carcinoma (SCC) of a testicular epidermal cyst. He is alive without recurrence or metastasis six months after surgery. Testicular SCC is an extremely rare tumor. This is the third case of testicular SCC associated with an epidermal cyst in English literature.
一名50岁的日本男性，有右侧阴囊无痛性肿块两年病史，前来我院就诊。结合实验室检查结果和计算机断层扫描，该患者被诊断为非典型睾丸肿瘤。初诊时影像学检查未发现转移。遂行急诊高位根治性睾丸切除术，术后病理显示肿瘤为睾丸表皮样囊肿伴鳞状细胞癌（SCC）。术后6个月，患者存活，无复发或转移。睾丸SCC是一种极其罕见的肿瘤。这是英文文献中第三例与表皮样囊肿相关的睾丸SCC病例。
