Primary hepatic yolk sac tumor is a rare extra-gonadal germ cell tumor in children and adults. Two important differential diagnoses for hepatic tumor in a pediatric patient are hepatocellular carcinoma and hepatoblastoma. A 22-month-old boy presented to our hospital with acute respiratory distress and increased serum alphafetoprotein. His symptom was caused by a ruptured massive intraabdominal ...
Purpose: Malignant ovarian germ cell tumors cause 5% of cancers. Studies examining prognosis and survival rates are significant due to malignant tumors' rarity. We aimed investigate outcome prognostic factors in these patients.
 Materials Methods: The study includes clinicopathological records tumor patients our clinic between April 1992 November 2017. Demographic clinical characteristics,...
Mixed germ cell tumours of the ovary are malignant neoplasms of the ovary comprising of two or more types of germ cell components. Most of the malignant mixed germ cell tumours consists of dysgerminoma accompanied by endodermal sinus tumours, immature teratoma or choriocarcinoma. There are only few case reports of mixed germ cell tumours with different combinations of malignant components. We r...
Primary intracranial germ cell tumors are rare, representing less than 5% of all central nervous system tumors. Overall, the majority of germ cell tumors are germinomas and approximately one-third are non-germinomatous germ cell tumors (NGGCT), which include teratoma, embryonal carcinoma, yolk sac tumor (endodermal sinus tumor), choriocarcinoma, or mixed malignant germ cell tumor. Germ cell tum...
hemangiomas of the sinonasal tract are rare, and because these lesions lack the typical signs or symptoms, they can be confused with other malignant conditions. we report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. although computed tomography (ct) and magnetic resonance imaging (mri) showed several enhanci...
Pineoblastomas are rare, malignant pineal parenchymal tumors encountered predominantly in pediatric patients. They distinct from primitive neuroectodermal (PNET) at other sites that they exhibit photosensory differentiation including Flexner–Wintersteiner rosettes and fleu-rettes. Diagnosis can be challenging since share morphologic immunohistochemical fea-tures with embryonal the developing gl...
