Retrorectal tumors are a rare group of neoplasms that occur most commonly in the neonatal and infant population. They vary in presentation, but teratomas are the most common and often present as a protruding mass from the sacrococcygeal region. Immediate surgical resection is indicated when found and coccygectomy is performed to prevent recurrence. When teratomas recur, the patients most often have vague symptoms and the tumors usually have malignant transformation. Here, we present the case of a young woman who underwent surgical resection of a sacrococcygeal teratoma at 3 days of age where the coccyx was not removed. She presented at 31 years of age with lower extremity paresthesias and radiography revealed a cystic mass extending from the sacrum. After resection, pathology revealed a recurrent teratoma with nests of adenocarcinoma.
直肠后肿瘤是一组罕见的肿瘤，最常见于新生儿和婴儿群体。它们的表现各不相同，但畸胎瘤最为常见，通常表现为从骶尾部突出的肿块。发现后应立即进行手术切除，并进行尾骨切除术以防止复发。当畸胎瘤复发时，患者通常症状不明确，肿瘤通常已发生恶变。在此，我们报告一例年轻女性病例，她在3日龄时接受了骶尾部畸胎瘤手术切除，但未切除尾骨。她在31岁时出现下肢感觉异常，影像学检查显示有一个从骶骨延伸的囊性肿块。切除后，病理检查显示为复发性畸胎瘤，伴有腺癌巢。
