Abstract：
Non-seminomatous germ cell tumors with structural components from all three cellular lineages are called teratomas. We report a rare case of a primary right adrenal teratoma in a postmenopausal female, presenting with abdominal pain. Ultrasound revealed a complex cystic shadow in the perihepatic region superior to the upper pole of the right kidney, which was suggestive of a complex supra-renal space-sequence-occupying lesion. Computerized tomography revealed a large-sized mature single multilobulated complex cystic lesion in the right hypochondrial lumbar region arising from the right adrenal gland. A right-sided transperitoneal adrenalectomy was performed. The resected mass (18 × 13 × 10 cm) was well encapsulated. Cut surfaces showed cystic mass filled with necrotic gray-white pultaceous material, along with a solid white gelatinous area. Microscopic sections showed a tumor which displayed differentiation along various tissue lineages. After immunohistochemical examinations, the tumor was confirmed to be a mature cystic teratoma. Mature teratomas show a good prognosis, and surgical resection and follow-up remain the standard approach.
摘要：
具有来自所有三个细胞谱系的结构成分的非精原细胞生殖细胞肿瘤被称为畸胎瘤。我们报道了一名绝经后女性原发性右肾上腺畸胎瘤的罕见病例，表现为腹痛。超声显示右肾上极上方肝周区域有一个复杂的囊性影，提示复杂的肾上间隙序列占位性病变。计算机断层扫描显示，右肾上腺下腰区域有一个大尺寸的成熟单个多小叶复杂囊性病变。进行了右侧经腹膜肾上腺切除术。切除的团块(18×13×10cm)被很好地包封。切面显示囊性肿块充满坏死灰白色牙髓质材料，以及固体白色凝胶状区域。显微镜切片显示肿瘤沿各种组织谱系显示分化。免疫组织化学检查后，该肿瘤被证实为成熟的囊性畸胎瘤。成熟畸胎瘤预后良好,手术切除和随访仍然是标准方法。
