The germ cells first appear from the primitive streak, the splanchnopleure and the allantoic membrane of the embry and they migrate toward the gonadal ridge. It can happen, however, that some of these germ cells may not migrate to the gonadal ridge and may remain at ectopic sites such as the mediastium, the central nervous system, the sacrococcygeal region and the retroperitoneum. Therefore, germ cell tumors can arise 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 whose 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 follows: 1) In total 412 cases, the ratio of benign to malignant tumors was 5.8:1. 2) Germ cell tumors occur commonly in the ovary (326 cases: 78.6%). It's incidence was followed by the descending order, in the mediastinum (26 cases: 6.3%), testis (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) In extragonadal sites, female were much more common and the sex ratio (M:F) showed 1:10 in sacrococcygeal region. 1:2.5 in retroperitoneum and 1:2.3 in mediastinum. 4) Mature teratoma was found most commonly (85.4%). It's incidence was followed by in descending order, seminoma (including dysgerminoma and germinoma) (6.8%), embryonal carcinoma (2.9%), endodermal sinus tumor (2.0%), immature teratoma (1.7%) and mixed forms (1.2%). 5) Benign teratoma takes up mostly at ovary, retroperitoneal space, sacrococcygeal region and mediastinum by 93.3%, 100.0%, 81.8%, 80.9%, respectively. But in testis and intracranial region, malignancy were more common. 6) Embryonal carcinoma and endodermal sinus tumor occured at similar aged group and each was distributed 41.7% and 62.5% respectively at first decade. 87.5% of dysgerminoma occured at 11~30 aged group, 91.7% of germinoma at 11~20 aged group, 67% 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. 7) 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. 8) The incidence of bilaterality were 10.2% in mature teratoma, 12.5% in dysgerminoma and 16.7% in seminoma. 9) When the corredation of the tumor markers, alphafetoprotein and human chorionic gonadotropin, with malignancy was checked in 12 out of 28 cases of tumor of the testis. Either alpha fetoprotein of human chorionic gonadotropin was found to be elevated in 3 cases (75%) 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 (12.8%).

Goltz syndrome is known as a rare mesoectodermal hereditary disease, characterized by focal dermal atrophies with hernias of adipose tissue and also associated with a multitude of possible skeletal, dental, ophthalmological and other abnormalities. We experienced a case of Goltz syndrome. An one day old female newborn had focal atrophic and telangiectatic skin lesions, microphthalmia, syndactyly and urinary tract abnormality. The finding of skin biopsy was consistent with focal dermal hypoplasia. We report the case with a brief review and related literatures.

BACKGROUND: About 30% to 40% of the patients with pathologic stage I non-small cell lung cancer (NSCLC) die within 5 years after complete resection. The identification of poor prognostic factors and the application of additional treatment are very important to improve the survival rate in resected stage I NSCLC. MATERIALS AND METHODS: Sixty-eight (68) patients who had been diagnosed postoperatively between Janury 1989 and December 1995 as having stage I non-small cell lung cancer according to the TNM classification were studied. The postoperative 5-year survival rate was calculated with the Kaplan-Meier method, and clinico-histopathologic factors including age, sex, operative method, type of tumor cell, T factor, grade of the differentiation in a squamous cell carcinoma, invasion of blood vessel and expression of the nm23-H1 protein were investigated and analyzed. RESULTS: The median survival of the entire group of patients was 58+/-3 months, with a 5-year survival of 58.9%. In univariate analysis, invasion of blood vessel and poor differentiation of the tumor cell in a squamous cell carcinoma significantly worsened the survival. In multivariate analysis, invasion of blood vessel and grade of the differentiation of the tumor cells in a squamous cell carcinoma remained independent prognostic factors. High expression of the nm23-H1 protein was related to a high postoperative 5-year survival in comparision with low expression of the nm23-H1 pretein (73.0% vs 50.7%), but there was no statistical significance. CONCLUSIONS: These results highlight the negative prognostic value of poor differentiation of tumor cells in a squamous cell carcinoma and invasion of blood vessel in stage I non-small cell lung cancer. Also, further studies are necessary to be determined prognostic value of the T factor and expression of the nm23 protein in non-small cell lung cancer.

Squamous cell carcinoma is the most common type of oral cancer and odontogenic myxoma is relatively uncommon benign tumor of mesenchymal origin. There are, to our knowledge, no prior reports of simultaneously occurring squamous cell carcinoma and odontogenic myxoma of the jaw bones. In this case, at first, the plain films and computed tomograms revealed a large expansile multilocular radiolucent lesion on left mandible and marked expansion of cortical plate. In addition this radiograms revealed also infiltrative bony destruction of anterior and medial border of ascending ramus of left mandible and alveolar bone of left maxilla, floating teeth on left lower molar area and metastatic enlargement of left submandibular, jugular digastric and spinal accessory lymphnodes. Magnetic resonance imaging of this patient revealed infiltrative growth of tumor on alveolar bone of left maxilla, left retromolar fat pad, left masseter and left medial pterygoid muscle. Intraoral presurgical biopsy presented typical features of squamous cell carcinoma. After chemotherapy with radiation therapy during 6 months, this central lesion was diagnosed as odontogenic myxoma by the postsurgical biopsy. After 3 months, this patient presented multiple metastatic signs at lumbar spines, rib and liver. Consequently, our case is simultaneous occurrence of squamous cell carcinoma and odontogenic myxoma.
