Teratoma is a germ-cell tumor that commonly affects the gonads. Its components originate in the ectoderm, endoderm, and mesoderm. Extragonadal occurrence is rare. Teratomas confined to the adrenal gland are exceptional; only 3 cases have been reported in the English-language literature. We report 2 cases of mature teratomas of the adrenal gland that were laparoscopically excised.
Two patients (ages 8 and 61 years) were diagnosed with adrenal teratoma at our institution. Radiological examination showed a solid 8-cm adrenal lesion in both cases. Hormonal assessment was normal. Both patients underwent laparoscopic transperitoneal adrenalectomy.
Surgical time was 120 minutes and 50 minutes, respectively. One patient was discharged on postoperative day 2, and the other remained hospitalized until day 10. The latter patient required percutaneous drainage of a retroperitoneal collection. Both tumors were identified as mature cystic teratomas. No evidence was present of recurring disease in either patient.
Adrenal teratoma is rare. Laparoscopic transperitoneal adrenalectomy is a feasible, effective technique that enables excellent oncologic results. To our knowledge, this is the first report of laparoscopic adrenalectomy for pure adrenal teratoma.
畸胎瘤是一种常见于性腺的生殖细胞肿瘤。其成分起源于外胚层、内胚层和中胚层。性腺外发生的情况罕见。局限于肾上腺的畸胎瘤更是罕见；英文文献中仅报道过3例。我们报告2例经腹腔镜切除的肾上腺成熟畸胎瘤病例。
我们机构的两名患者（年龄分别为8岁和61岁）被诊断为肾上腺畸胎瘤。影像学检查显示两例患者均有一个8厘米的肾上腺实性病变。激素评估正常。两名患者均接受了腹腔镜经腹肾上腺切除术。
手术时间分别为120分钟和50分钟。一名患者术后第2天出院，另一名患者住院至第10天。后一名患者需要对腹膜后积液进行经皮引流。两个肿瘤均被确诊为成熟囊性畸胎瘤。两名患者均无疾病复发迹象。
肾上腺畸胎瘤罕见。腹腔镜经腹肾上腺切除术是一种可行、有效的技术，能取得良好的肿瘤治疗效果。据我们所知，这是首例关于单纯肾上腺畸胎瘤腹腔镜肾上腺切除术的报告。
