We report here a rare case of adult sacrococcygeal teratoma (SCT) that was pathologically diagnosed as signet ring cell carcinoma (SRCC). A 26-year-old man complained of lower abdominal distension and discomfort and difficulty in urinating, and he was admitted to our hospital. Pelvic magnetic resonance imaging showed multiple oval, solid-cystic masses around the anterior sacrococcygeal region that measured approximately 96 × 114 × 89 mm. Magnetic resonance imaging also showed irregular cysts around the posterior sacrococcygeal region that measured approximately 34 × 72 × 60 mm. The preliminary diagnosis was cystic SCT. The patient then underwent surgery, during which we incised the cysts. A large amount of viscous, jelly-like liquid was present in the anterior sacrococcygeal mass. Furthermore, a large amount of light yellow, porridge-like secretion was present in the posterior sacrococcygeal mass. A pathological examination and immunohistochemistry confirmed teratoma, specifically SRCC.
我们在此报告一例罕见的成人骶尾部畸胎瘤（SCT），经病理诊断为印戒细胞癌（SRCC）。一名26岁男性主诉下腹胀满不适及排尿困难，遂入住我院。盆腔磁共振成像显示骶骨前区域周围有多个椭圆形实性囊性肿块，大小约为96×114×89mm。磁共振成像还显示骶骨后区域周围有不规则囊肿，大小约为34×72×60mm。初步诊断为囊性SCT。患者随后接受手术，术中切开囊肿。骶骨前肿块中有大量粘稠的胶冻样液体。此外，骶骨后肿块中有大量浅黄色粥样分泌物。病理检查及免疫组化证实为畸胎瘤，具体为SRCC。
