本文总结了1970～1979年间我院小儿骶尾部畸胎瘤54例。其中女性35例(65％),男性19例(35％),女性明显居多。三种病理类型及其随访结果,(1)成熟型畸胎瘤,只含成熟组织,此型共35例(65％),其中30例健在,1例因伴有脊髓膨出,于术后死亡,4例失访。(2)未成熟型畸胎瘤,含有成熟及胚胎性组织。此型共8例(15％),6例健在(其中随访五年以上者4例),2例因术后复发死亡。(3)恶性畸胎瘤,此型共11例(20％),其中包括9例卵黄囊癌,2例胚胎癌。已知随访结果的7例,均于术后一年内死亡。4例失访。便泌或伴有尿潴留等症状,可为临床诊断提供线索,特别当肿瘤位于盆腔内、而外观无异常所见者。此症状在恶性骶尾部畸胎瘤出现率明显增高。本文对该瘤的组织发生,年龄与良、恶性的关系,病理组织类型与预后的关系等进行了讨论。
This article summarizes 54 cases of pediatric sacrococcygeal teratoma in our hospital from 1970 to 1979. Among them, 35 were women (65%), 19 were males (35%), and the majority were females. Three pathological types and their follow-up results, (1) mature teratoma, containing only mature tissue, this type a total of 35 cases (65%), of which 30 were alive, 1 due to spinal cord bulging, Death, 4 cases were lost. (2) immature teratoma, containing mature and embryonic tissue. There were 8 cases (15%), 6 cases were alive (4 cases were followed up for more than five years) and 2 died of recurrence. (3) Malignant teratoma, this type a total of 11 cases (20%), including 9 cases of yolk sac cancer, 2 cases of embryonal carcinoma. Known follow-up results of the seven cases, were within one year after the death. 4 cases were lost. Constipation or associated with urinary retention and other symptoms, can provide clues for clinical diagnosis, especially when the tumor is located in the pelvic, and the appearance of no abnormal seen. This symptom of malignant sacrococcygeal teratoma was significantly higher. This article discusses the occurrence of the tumor, the relationship between age and benign and malignant, the relationship between pathological type and prognosis.
