摘要

Intratesticular epidermoid cysts are rare benign tumors of the testes. Based on the World Health Organization classification of the tumors of the urinary system and male genital organs (2016), testicular epidermoid cysts are classified as prepubertal-type teratomas. We herein present the case of a 30-year-old male suffering from a left testicular mass for three months. Physical examination confirmed a 2-cm, hard, nontender testicular mass in the left scrotum. Ultrasonography revealed a 2.1 × 2.1-cm solid mass without hypervascularity in the lower testicular pole. Serum α-fetoprotein and human chorionic gonadotropin levels were normal. Orchidectomy was performed based on the preoperative diagnosis of benign left testicular tumor, which was pathologically confirmed as intratesticular epidermoid cyst, a prepubertal-type teratoma. We also review the literature and discuss the correlation of scrotal ultrasound findings with pathological features.

睪丸內表皮樣囊腫（青春期前畸胎瘤）是良性而且少見的睪丸腫瘤，本文報告一位30歲男性左邊睪丸有一個腫塊大約有3個月時間，理學檢查大約為2公分睪丸內不會觸痛的腫塊，超音波檢查發現在左睪丸實質下方有2.1公分實質腫瘤,無血流量增加現象，而且病人血中α胎兒蛋白以及絨毛膜激素均正常，手術前診斷為左側良性睪丸腫瘤，做了睪丸摘除術。本文報告此一少見的睪丸良性腫瘤，討論其陰囊超音波診斷及病理特徵的相關性。
