Sacrococcygeal teratomas are rare congenital tumours that are even more uncommon when present in adulthood. They are derived from residual stem cells in the presacral space that differentiate into clusters of somatic cell. We present the diagnosis, management and post-operative follow-up in a 37-year-old gentleman referred to our department with an incidental finding of a lobulated presacral cystic mass on computed tomography imaging. Magnetic resonance imaging and fluorodeoxyglucose (FDG)-positron emission tomography (PET) scans were performed to further characterize the lesion. The decision was then made for surgical excision and the specimen along with the coccyx was retrieved en-bloc via a trans-sacral surgical approach. Histopathology of the mass uncovered the presence of squamous, respiratory and prostatic epithelium consistent with the diagnosis of a sacrococcygeal teratoma.
骶尾部畸胎瘤是一种罕见的先天性肿瘤，在成年期出现则更为罕见。它们源自骶前间隙中的残余干细胞，这些干细胞分化为体细胞簇。我们报告了一名37岁男性患者的诊断、治疗及术后随访情况，该患者因计算机断层扫描成像偶然发现骶前分叶状囊性肿块而转诊至我科。进行了磁共振成像和氟脱氧葡萄糖（FDG）-正电子发射断层扫描（PET）以进一步明确病变特征。随后决定进行手术切除，并通过经骶骨手术入路整块切除标本及尾骨。肿块的组织病理学检查发现存在鳞状、呼吸和前列腺上皮，符合骶尾部畸胎瘤的诊断。
