Teratomas of the testis account for 4% of all testicular tumors. Monodermal variants (eg, epidermal inclusion cysts) account for less than 1% of all these tumors. To our knowledge, we are reporting the first case of pilomatricoma of the testis, a monodermal teratomatous tumor of follicular differentiation, with secondary heterotopic ossification. The differential diagnosis of the characteristic "shadow" cells is discussed, and the significant literature on both benign and malignant ossifying lesions of the testis is reviewed.
睾丸畸胎瘤占所有睾丸肿瘤的4%。单胚层变体（如表皮包涵囊肿）占所有这些肿瘤的比例不到1%。据我们所知，我们报告了首例睾丸毛母质瘤，这是一种具有滤泡分化的单胚层畸胎瘤，并伴有继发性异位骨化。文中讨论了特征性“影子”细胞的鉴别诊断，并回顾了关于睾丸良性和恶性骨化性病变的重要文献。
