We report an unusual case of adenocarcinomatous transformation of a paracoccygeal teratoma (PCT) in a 44-year-old woman. The patient was referred to us for surgical treatment of a growing paracoccygeal mass. The findings of a magnetic resonance imaging scan were compatible with soft tissue malignancy. Using the posterior approach, we performed complete surgical removal with coccygectomy. Histological examination of the cystic mass revealed a mature teratoma containing primary adenocarcinoma. The patient has been followed up for 7 years and is free of disease. Because prognosis depends on complete excision, we emphasize the importance of clear-margin surgery, including en bloc removal of the coccyx.
我们报告了一例44岁女性尾骨旁畸胎瘤（PCT）发生腺癌转化的罕见病例。该患者因尾骨旁不断增大的肿块前来我院接受手术治疗。磁共振成像扫描结果提示软组织恶性肿瘤。我们采用后路入路，行尾骨切除术并完整切除肿瘤。对囊性肿块进行组织学检查，发现为成熟畸胎瘤伴原发性腺癌。该患者已随访7年，无疾病复发。由于预后取决于完整切除，我们强调切缘阴性手术的重要性，包括整块切除尾骨。
