dc.description.abstract[한글] 생식세포는 배아 원시색, 장측판 및 요각 중배엽에 처음 나타나서 성선릉으로 이동하는데 이중 일부는 생식선에 이르지 못하고 이소부위에 머무를 수 있기 때문에 고환이나 난소외에 종격동, 중추신경계, 천미골부, 후복막 .등의 이소부위에도 생식세포 기원의 종양이 발생 할 수 있으며. 또한 생식세포는 배아조직과 융모막조직 및 난황막과 같은 배아외조직으로 분화하는 다분화능을 가지고 있으므로 그 발달단계와 분화방향에 따라 각기 다른 종류의 종양이 발생할 수 있다. 저자는 이러한 생식세포 종양의 전신적인 분포와 그 임상 및 병리학적 측면에 관한 연구가 미비한 점을 감안하여 1976년부터 1985년까지 만 10년간 연세대학교 의과대학 병리학 교실에서 생식세포 종양으로 진단되었던 총 412예를 분석하였던 바, 다음과 같은 결과를 얻었다. 1) 총 412예의 생식세포 종양중 양성 종양이 352예 (85.4 %), 악성 종양이 67예 (14.6 %)로 양성 종양이 악성에 비해 5.8:1의 높은 빈도를 보였다. 성별 분포를 보면 난소 326예와 고환 23예를 제외하면, 생식선외 부위는 천미골부 1 : 10, 후복막 1 : 2.5, 종격동 1 : 2.3등으로 여자에 월등히 많아, 부위에 따라 성별의 발생차이가 있었다. 2) 생식세포 종양은 난소에 326예(78.9 %)로 가장 많이 발생하였고, 종격동에 26예 (6.3%), 고환에 23예 (5.6%), 중추신경계에 15예(3.6%), 천미골부에 11예(2.7%), 후복막에 7예 (1.7 %)가 발생하였으며, 그외 안와, 심외막, 신장에 각각 2예,1예, 1예씩 분포하였다. 3) 조직학적 유형을 보면, mature teratoma가 85.4%로 가장 많았고, 그 다음은 seminoma (dysgerminoma, germinoma포함) (6.8%), 그리고 embryonal carcinoma (2.9%), endodermal sinus tumor (2.0%), immature teratoma (1.7%), mixed form (1.2 % )의 순이었다. 4) 발생부위별 조직학적 유형을 보면 난소, 후복막, 천미골부 및 종격동에서는 benign teratoma가 각각 93.3%, 100.0%, 81.8%, 80.9 %로 생식세포 종양의 대부분을 차지하였으나, 고환과 두개내에서는 악성 종양이 더 많았다. 5) 조직학적 유형별 연령 분포를 보면, mature teratoma는 20∼40세에 67.0 %, seminoma는 31∼50세에 75.0%, dysger-minoma는 11∼30세에 87.5 %, germinoma는 11∼20세에 91.7%, embryonal carinoma와 endodermal sinus tumor는 10세 이전에 각각 41.7%, 62.5%가 발생하여, 전체적으로 embryonal carinoma, endodermal sinus tumor, dysgerminoma / germinoma, mature teratoma, seminoma의 연령순을 보였다. 6) Mature teratoma 352 예중, 347예 (98.6%)는 cystic type이었고, solid type은 5예 (1.4%)에 불과하였다. Immature teratoma 7예 중에서는 5예 (71.4%)가 solid type이었고, 2예 (28.6%)가 cystic type이었다. 7) 양측성은 mature teratoma에서는 10.2%, dysgerminoma와 seminoma에서는 각각 12.5%와 10.7%였다. 8 )고환의 생식세포 종양 23예중 12예에서 혈청 αFP과 MCG가 시행되었으며, 그중 4예에서 αFP이나 HCG의 증가를 보였고,αFP이나 HCG가 증가된 4예중 3예(75.0%)는 진단 당시 폐, 복막 혹은 임파절 전이를 보였으며, αFP이나 HCG가 증가되어 있지 않은 8예중에서는 1예(12.5%)만이 임파절 전이를 보였다. [영문] The germ cells first appear from the primitive streak, the splanchnopleure and the allantoic membrane of the embryo and they migrate toward the gonadal ridge. It can happen, however, that some of these germ cello may not migrate to the gonadal ridge and may remain at ectopic states such as the mediastinum, the central nervous systems the sacrococcygeal region and the retroperitoneum. Therefore, germ cell tumors can arose from these ectopic sites and according to their totipotentiality of differentiating into embryonic and extraembryonic tissues, such as chorionic tissues and yolk sac, they can develop into various tumors. Generally, the sites in which these tumors are frequently found are the gonads, the sacrococcygeal region, the mediastinum, the retroperitoneum and the intracranial region. The aim of this study was to organize and report the data found on these tumors in the records of 412 patients where tumor specimens were examined in the Department of Pathology of the Yonsei University, college of Medicine within the 10 year period, 1976 - 1985. The findings are as fellows: 1) In total 412 cases, the ratio of benign tumors to malignant was 5.8:1. In extragonadal sites, female were much more common and the sex ratio showed 1:10(M:F) in sacrococcygeal legion, 1:2.5 in retroperitoneum and 1:2.3 in mediastinum. 2) According to the site of distribution, the most common at ovary; 326. cases (78.6%) and in decreasing order, mediastinum; 26 cases (6.3%), testes: 23 cases (5.6%), central nervous system; 15 cases (3.6%), sacrococcygeal region; 11 cases (2.7%) and retroperitoneal space; 7 cases (1.7%). Also, 2 were found in the intraorbital region and 1 each in the pericardium and the kidney. 3) According to the histological distribution, mature teratoma was the most common (85.4%) and in decreasing order, seminoma (including dysgerminoma and germinoma) (6.8%), embryonal carcinoma (2.9%), endodermal ainus tumor (2.0%), immature teratoma (1.7%) and mixed forms (1.2%). 4) According to the histological types, organic distributions are as fellows ; benign teratoma takers up mostly at ovary, retroperitoneal space, sacrococcygeal region and mediastinum by 93.3%, 100.0%, 81.8% and 80.9%, respectively. But in testis and intracranial legion, malignancy were more common. 5) According to the age distribution of germ cell tumors, embryonal carcinoma and endodermal sinus tuner occurred at similar aged group and each was distributed 41.7% and 62.5% respectively at first decade. 87.5% of dysgerminoma occurred at 11-30 aged group, 91.7% of germinoma at 11-20 aged group, 67% of mature teratoma at 20-40 aged group, 75% of seminoma at 31-50 aged group, so age distribution showed embryonal carcinoma, endodermal sinus tumor, dysgerminoma/germinoma, mature teratoma and seminoma, in increasing order. 6) In 352 cases of mature teratoma, 347 cases (98.6%) were cystic type and 5 cases (1.4%) were solid type. In 7 cases of immature teratoma, 5 cases (71.4%) were solid and 2 cases (28.6%) were cystic. 7) The incidence of bilaterality were 10.2% in mature teratoma, 12.5% in dysgerminoma and 16.7% in seminoma. 8) When the correlation of the tumor markers, alpha-fetoprotein and human chorionic gonadotropin, with malignancy was checked, in 12 out of 28 cased of tumor of the testis, either alpha fetoprotein or human chorionic gonadotropin was found to be elevates in 3 cases (75.0%) in which metastasis was already present at the time of diagnosis, where in 8 cases in which neither marker was elevated metastasis was found to be present in only 1 (l2.8%).-
