Epidermoid cysts os the testes have an incidence between 1-2% of total tumours in that organ. The embryonary origin of this benign neoplasia is unknown, although the most widely accepted theory is they are monodermal teratomas. Differential diagnosis with germinal cells is established through the characteristic dartboard-like ultrasound image, which allows testicular conservant surgery though only in the case of certainty about the lesion. Since that was not the case and given the ultrasound variability recorded in the literature, radical orchiectomy was performed to overcome the persistent doubt at staging the tumour's benignancy.
睾丸表皮样囊肿占该器官肿瘤总数的1%-2%。这种良性肿瘤的胚胎起源尚不清楚，尽管最被广泛接受的理论是它们是单胚层畸胎瘤。通过特征性的靶心样超声图像与生殖细胞肿瘤进行鉴别诊断，这使得睾丸保留手术成为可能，但前提是对病变有确定性诊断。由于实际情况并非如此，且考虑到文献中记录的超声表现存在变异性，为消除对肿瘤良性分期的持续疑虑，实施了根治性睾丸切除术。
