Case report of a mature cystic teratoma (dermoid cyst), pseudopilomatrixoma like variant.
53-year old patient with a left testicular mass, diagnosed as mature cystic teratoma of the testis(dermoid cyst), the pilomatrixoma-like variant, after radical orchiectomy. Tumoral markers were negative and no extension was observed. The patient is disease-free after 6 months follow-up.
Testicular teratoma is a tumour composed of cells derived from the three embryonic layers (ectoderm, endoderm and mesoderm). They can appear at any age, but they are much more prevalent in childhood. They appear at any age, but are much more common in childhood, where they comprise up to 30% of all tumours. They are much less prevalent in adults,representing only 7% of all testicular germ cell tumours
Prepubertal cases are invariably benign in nature, regardless of their histology. However, cases which appear after puberty are potentially malignant, even if histologically pure. Mature cystic teratoma (dermoid cyst) is the only exception to this rule, as no malignant degeneration of these types of tumours has been published.
成熟囊性畸胎瘤（皮样囊肿）类毛母质瘤样变体的病例报告。
一名53岁男性患者，左侧睾丸有肿块，根治性睾丸切除术后诊断为睾丸成熟囊性畸胎瘤（皮样囊肿），类毛母质瘤样变体。肿瘤标志物为阴性，未观察到肿瘤扩散。随访6个月后患者无疾病复发。
睾丸畸胎瘤是一种由源自三个胚层（外胚层、内胚层和中胚层）的细胞组成的肿瘤。它们可在任何年龄出现，但在儿童期更为常见。它们在任何年龄都可出现，但在儿童期更为常见，占所有肿瘤的30%。在成人中则较为少见，仅占所有睾丸生殖细胞肿瘤的7%。
青春期前病例无论组织学类型如何本质上均为良性。然而，青春期后出现的病例即使组织学上为纯性也有潜在恶性可能。成熟囊性畸胎瘤（皮样囊肿）是该规则的唯一例外，因为尚未有此类肿瘤发生恶性变的报道。
