Mature teratoma of the uterine corpus with thyroid differentiation

A case of a clinically silent mature teratoma of the uterine corpus is reported. A 55-year-old woman presented with multiple uterine leiomyomas. The discovery was incidental, because the patient was asymptomatic. Macroscopically, a colloid-hemorrhagic-looking nodule was present. Histologic and immunohistochemical studies showed that this tumor was a small thyroid mass. Key words:,     

Alpha-Fetoprotein Subtractions in Germ Cell Tumors Identified by Con A or LCH Crossed-Line Affinity Immunoelectrophoresis

ABSTRACT: Using concanavalin A (Con A) crossed-line affinity immunoelectrophoresis and lentil lectin (LCH) crossed-line affinity immunoelectrophoresis, alpha-fetoprotein (AFP) subfractions were studied in sera including three sera from nude mice heterotran-splanted with human yolk sac tumor of the ovary and three sera from patients with yolk sac tumor, mature solid teratoma, or immature solid teratoma of the ovary. In sera of nude mice bearing yolk sac tumor or from a patient with yolk sac tumor, subfractions from yolk sac and those from fetal liver were identified. Since AFP subfractions from yolk sac and fetal liver can be differentiated according to the carbohydrate moieties, our findings indicate that AFP produced by yolk sac tumor and fetal yolk sac are to some extent differently glycosylated. We also found that AFP in both mature and immature solid teratoma was composed of two subfractions ontogenetically originating from yolk sac or fetal liver. All these findings indicate that more than two different factors are responsible for the AFP synthesis in germ cell tumor of the ovary.     

卵巢未成熟畸胎瘤临床特征及分析

目的;探讨未成熟畸胎瘤的临床特征,方法：对1979年8月至1999年7月收治的49例卵巢未成熟畸胎瘤进行回顾性分析。结果：49例卵巢未成熟畸胎瘤患者30岁以下者占75．49％,临床分期I期26例,II期6例,III期13例,IV期4例,其中实行保守性手术的5年生存率较根治性手术5年生存率稍低但无统计学差异,49例中发生于单仙卵巢的占88．2％,其中左侧占53．6％,结论：卵巢未成熟畸台瘤主要发生在青少年,单侧尤其左侧卵巢好发,临床分期与预后有关,手术方式与生存率无必然规律,对年轻患者要求生育者,可考虑保行留生育功能的手术方式。     

超声对卵巢畸胎瘤的诊断价值

为探讨超声对卵巢畸胎瘤的诊断价值 ,对 76例经手术病理证实为卵巢畸胎瘤 (包括成熟和未成熟型 )的声像图进行分析。结果 76例畸胎瘤中 ,超声诊断 6 9例 ,符合率 90 .8%。其中单侧 6 5例 ,双侧 11例 ,共 87枚。声像图表现为三种类型 :囊性型 ( 3例 3枚 ) ,假实性 ( 10例 13枚 ) ,混合性 ( 6 3例 71枚 ) ,以混合性多见。认为超声是卵巢畸胎瘤的首选检查方法 ,特别是良性畸胎瘤的声像图具有特征性 ,而未成熟畸胎瘤的声像图无一定特征性 ,确诊有赖于手术及病理     

ONCOPROTEINS AND TUMOR SUPPRESSOR PROTEINS IN CONGENITAL SACROCOCCYGEAL TERATOMAS

Congenital sacrococcygeal teratoma SCT is the most common germ cell tumor of infancy and childhood with a female preponderance. Most SCTs are diagnosed at birth, are benign, and consist of fully differentiated, mature tissues. Tumorigenesis of SCTs remains poorly understood. Almost nothing is known about possible oncogene activation or tumor suppressor inactivation in these rare tumors. We describe the presence of various oncoproteins and tumor suppressor proteins in eight cases of congenital SCT. The following oncogenes were examined: ras family c-H-, c-N-, and c-K-ras , early genes fos, jun , and tumor suppressor genes p53 and nm23-H-1 . There was no relationship between the intensity of expression of these oncoproteins and tumor suppressor genes and the following parameters: tumor size, age, and survival of the patients. We did not observe any difference, however, between the expression of the examined oncogenes and tumor suppressor genes nm23 and p53 in immature and mature teratomas. Our findings suggest that the ras family of oncogenes, fos and jun oncogenes, and nm23 and p53 tumor suppressor genes are present in congenital SCT, indicating a possible role in genesis and development of these tumors.     

小儿恶性骶尾部畸胎瘤的治疗及预后(附26例报告)

目的：探讨小儿恶性骶尾部畸胎瘤特点、诊治方法及预后。临床资料：26例中，男11例，女15例。病理分恶性畸胎瘤9例，卵黄囊瘤门例。结果：26例中，24例经手术治疗，其中16例为晚期肿瘤，术后自动出院，短期内死亡；6例分别于半年内死亡；1例原为良性，半后复发，再术后2个月死亡；1例卵黄囊瘤，术后坚持每月化疗1次，开始好，AFP下降，全身情况好，1年后复发，放弃治疗。结论：提出早诊断、早手术、术前明确诊断要点、术后采取联合化疗、放疗等综合措施。影响预后的主要因素是就诊太晚，特别是隐性患儿，肛诊易发现。     

Placental teratoma: A case report

We present a rare case of a placental teratoma found within the fetal membranes of an otherwise normal placenta. Lack of a recognizable umbilical cord and no recognizable skeletal development are used as differential diagnostic criteria for a placental teratoma. In our case, an umbilical cord was absent; nevertheless, the tumor contained two vascular channels covered only by fetal membranes without Wharton's jelly.     

Trichoptysis caused by intrapulmonary teratoma: Computed tomography and magnetic resonance imaging findings

We describe a 9-year-old child with a history of trichoptysis caused by intrapulmonary teratoma and we present the CT and MRI findings of the teratoma. A heterogeneous mass containing cystic and solid elements was detected on both CT and MRI scans. Histopathological examination confirmed the diagnosis of teratoma. Teratomas arising from lung parenchyma, as in this case, are extremely rare in childhood. In the thoracic region, the most common localization of teratomas is the anterior mediastinal compartment. We also discuss the CT and MRI findings and the differential diagnosis of teratomas.     

熟三七联合曲美他嗪治疗冠心病心肌缺血的临床观察

目的:开展熟三七联合曲美他嗪治疗冠心病心肌缺血的临床观察。方法:将冠心病心肌缺血的患者126例随机分为对照组、曲美组和联合用药组,每组42例。对照组口服阿司匹林肠溶片和单硝酸异山梨酯缓释胶囊;曲美组在对照组的基础上,增加口服盐酸曲美他嗪片;联合用药组在对照组的基础上,增加口服盐酸曲美他嗪片和熟三七粉。结果:相较对照组和曲美组,联合用药组能有效降低冠心病患者血液中TC、TG与LDL-C的水平,升高HDL-C的水平,显著改善临床症状。其总有效率可大幅度地提高至95.24%(P<0.05),而总不良反应发生率大幅度地降低至7.14%(P<0.01)。结论:熟三七联合曲美他嗪治疗冠心病心肌缺血疗效明确,建议在临床上推广应用。
