Teratomas develop most frequently in the sacrococcygeum and are often diagnosed by simple observation. Most sacrococcygeal teratomas are benign, and evident in the newborn. Females are affected four times more often than males, but affected males are more likely to have malignant tumors. Benign teratomas are generally noninvasive, cystic, and contain calcifications. Surgery is the primary, usually curative treatment, although malignant tumors can be treated effectively only by early diagnosis and removal. Twenty-six cases of sacrococcygeal teratoma were reviewed.
畸胎瘤最常发生于骶尾部，通常通过简单观察即可诊断。大多数骶尾部畸胎瘤是良性的，在新生儿中很明显。女性受影响的几率是男性的四倍，但受影响的男性更有可能患有恶性肿瘤。良性畸胎瘤通常是非侵袭性的、囊性的，并且含有钙化。手术是主要的治疗方法，通常可治愈，不过恶性肿瘤只有通过早期诊断和切除才能得到有效治疗。回顾了26例骶尾部畸胎瘤病例。
