Significant improvements in the management of ovarian germ-cell tumors have been achieved during the past two decades. The development of more effective chemotherapeutic regimens is clearly the leading cause for improved outcome for these patients. In addition, advancements in other disciplines led to the development of a more precise surgical staging system, improved radiographic imaging, more sophisticated pathology techniques, as well as improved supportive care and symptom control. A substantial majority of patients with ovarian germ-cell tumors are long term survivals and suffer minimal morbidity from treatment. Fertility-sparing surgical procedures enable a large proportion of young women with ovarian germ-cell tumors to preserve their reproductive potential.

For evaluation on the histopathologic studies and age distribution of the testicular tumors in the Taegu area, the inguinal orchidectomized materials were collected at the Department of Pathology, College of Medicine, Yeungnam University, and the analyzed results were as follows: 1. In total of 11 cases of orchidectomized materials, germ cell tumors are 10 cases (90.9%). In germ cell tumors according to the histologic types, seminoma was 5 cases (45.5%), and embryonal carcinoma, 3 (27.2%). 2. The highest age incidence of the group is 20th and 30th, and the next, 50th and 10th.

Malignant rhabdoid tumor is a distinct renal tumor in children. It had been regarded as a rhabdomyosarcomatoid variant of Wilms' tumor, but it is now thought as a separate entity. We report a case of malignant rhabdoid tumor of the kidney in a 26-month-old girl who presented with a left abdominal mass. Grossly, a large mass in the lower pole of the left kidney was well encapsulated and measured 4 x 4 x 3.5cm. On cross section, it was soft and yellowish white and showed multifocal necroses. The mass was mainly located in the medial medullary portion and compressed the renal pelvis laterally. Microscopically, the tumor masses were hypercellular and anaplastic without definite blastematous elements. In larger portion, the tumor cells had abundant eosinophilic cytoplasm and hyaline globules. In addition to the classic "rhabdoid" feature, alveolar, sclerosing, and lymphomatous patterns were seen. Ultrastructurally, tumor cells with abundant cytoplasm contained tangles of intermediate filament corresponding to vimentin in immunostaining.

A case of melanotic neuroectodermal tumor of infancy was presented. This tumor occurred in the right maxillary alveolar ridge of 3-month-old female infant, showing bluish enlargement of alveolar mucosa with the displacement of central deciduous incisor. We described the gross, microscopic, and ultrastructural findings of this tumor. This case appears to be the first case of MNTI, reported in a Korean.

OBJECTIVETo investigate the clinical characteristics and microsurgical managements of rare tumors in the sellar region.

METHODSSix rare cases of tumors in the sellar region treated by microsurgery from Jan 2000 to Jan 2010 were reviewed retrospectively. Subsequent treatments were according to the status of preoperative alpha fetal protein (AFP) and human chorionic gonadotropin (HCG) measurement as well as confirmed by histopathological examination in all six patients.

RESULTSTotal resection of the tumor was achieved in 2 cases and subtotal resection in 4 cases. Postoperative histopathology confirmed that the lesions were tumors in 5 cases and fungal pseudotumor in 1 case. Moreover, variety of histological types were observed in the present series, including leiomyosarcoma, malignant yolk sac tumor, mixed germ cell tumor, embryonal carcinoma, pilocytic astrocytoma and fungal pseudotumor, respectively. The serum levels of AFP and HCG were elevated to some extent in the patients with malignant yolk sac tumor, mixed germ cell tumor or embryonal carcinoma. Follow-up was conducted in all patients for 1 month to 3 years. The patients with malignant yolk sac tumor and embryonal carcinoma as well as leiomyosarcoma died in 5, 6, 10 months after operation, respectively. Subarachnoid hemorrhage occurred in the case of fungal pseudotumor at 2 months after surgery. The other two patients were surviving well.

CONCLUSIONSRare non-germinomatous malignant germ cell tumors are predominantly susceptible to the sellar region. Furthermore, High misdiagnosis rate and poor prognosis are characteristic in the present study. Dynamic AFP and HCG detection may play an important role in the diagnosis of those non-germinomatous malignant germ cell tumors located in the sellar region. The importance of awareness of the presence of such rare lesions in the sellar region is emphasized.
