Background: Primary mediastinal yolk sac tumor is an extremely rare and highly malignant tumors occuring in children and young adult. They are more common in men. The most common symptoms on ptesentation were dyspnea, chest pain, cought, fever, night sweat, or weight loss. Primary mediastinal tumor are considered to have poor prognosis. Case: A 18- year-old man who presented with shorthness of breath, chest pain, fever, night sweat, and generalized weakness. He had no significant surgical, familiy or social history. The chest X-Ray and computed tomographic scan of the chest showed a large anterior mediasti nal mass. The serum level of alpha- fetoprotein and β-HCG was elevated. The histological examination revealed the finding of yolk sac tumor. This supported the diagnosis of yolk sac tumor. The patient received a combination chemotherapy consisting of cisplatin, etoposide and bleomycin every 3 weeks for total of 4 cycles. Conclusions: Primary mediastinal yolk sac tumor is a rare tumor. The diagnosis should be made not only by morphological studies but the also the patients age and the elevation of serum alpha-fetoprotein. In spite of modern chemotherapy, the prognosis of mediastinal yolk sac tumor remains poor.

Abstract Background: Yolk sac tumor also known as endodermal sinus tumor, is a rare intracranial germ cell tumor. We reported a case of yolk sac tumor in cerebellar hemisphere, and reviewed associated literatures. The majority of tumor locations are near the midline. On review of literature, very few case reports of intracranial yolk sac tumor have been published, and there is only one case report has described a yolk sac tumor arising from the cerebellum. Case presentation: A two years old boy admitted to our hospital due to headache and unsteady gait for six days. CT and MRI demonstrated a tumor in the right cerebellar hemisphere, and the blood and cerebrospinal fluid alpha-fetoprotein were found increased. It was diagnosed as yolk sac tumor after operation comfirmed by histopathological examination. Postoperative chemotherapy was performed, and the patient suffered no tumor recurrence one year and a half after the surgery. Conclusions: The clinical characteristics and imaging diagnosis of intracranial yolk sac tumor are lack of specificity, the comfirmed diagnosis is depending on the combination of elevated alpha-fetoprotein and histopathological examination.

Abstract: Testicular cancer is relatively rare, accounting for less than 1% of malignant tumors affecting men. More than 90% of these tumors are of germ cell origin and most of them are found in young men between the ages of 15-34 years. Germ cell tumors are divided into seminoma and nonseminoma tumors. The seminoma makes up 30-40% of all testicular tumors. An anaplastic seminoma is a classic type of seminoma that has three or more mitosis under the high power microscopic field, combined with other morphologic criteria such as nuclear hyperchromasia, greater nucleolar sizes, pleomorphism, and an amount of necrosis. We reported a case of a 38-year-old male that was clinically diagnosed with a left testicular tumor and with an elevated alpha fetoprotein (AFP) and β human chorionic gonadotropin (β HCG) serum. The histopathological diagnosis was an anaplastic seminoma with a yolk sac tumor (YCT), i.e. a mixed germ cell tumor. Keywords: seminoma, testicular tumor, yolk sac tumor.   Abstrak: Kanker testis relatif jarang,  <1% dari semua kanker ganas pada laki-laki. Lebih dari 90 persen jenis tumor ini berasal dari sel germinal dan umumnya menyerang laki-laki muda berusia 15-34 tahun. Tumor sel germinal dibagi atas dua jenis: seminoma dan non seminoma. Jenis seminoma terdapat pada 30-40% dari seluruh tumor testis. Seminoma anaplastik adalah seminoma dengan ciri klasik mikroskopik berupa adanya tiga atau lebih sel-sel mitosis per lapangan pandang besar, disertai terdapatnya kriteria morfologik lain seperti inti sel hiperkromatik, anak inti berukuran besar, pleomorfik, dan terdapatnya sejumlah nekrosis. Kami melaporkan kasus seorang laki-laki berusia 38 tahun dengan diagnosis klinis tumor testis kiri disertai peningkatan kadar alfa feto protein (AFP) dan β human chorionic gonadotropin (β HCG) serum. Diagnosis histopatologik ialah  seminoma anaplastik dengan tumor yolk sac (YCT), yaitu tumor sel germinal campuran. Kata kunci: seminoma, tumor testis, tumor yolk sac.

A 6-year-old patient was admitted to the Petrovsky National Research Center of Surgery in Moscow, diagnosed with hepatoblastoma (HB) of the right lobe of the liver and after undergoing 4 cycles of SIOPEL (super PLADO) pre-operative chemotherapy. An immunohistochemistry test, performed after liver resection, revealed a rare combination of mixed epithelial and mesenchymal hepatoblastoma and yolk sac tumor. The epithelial component of HB consisted of highly differentiated fetal cells, while the mesenchymal component consisted of osteoid. The morphological structure of the second lesion corresponded to yolk sac tumor. Both tumors had regressive changes conditioned by chemotherapy: these changes were most pronounced in HB. In the highly differentiated fetal component of HB it was possible to detect a weak focal perinuclear alpha-fetoprotein expression, HepPar expression, membranous expression of beta-catenin and diffuse glutamine synthetase expression. Mitotic figures were not determined. The node of the yolk sac tumor had the characteristic histological structure of an endodermal sinus tumor with a hepatoid component. In the main tumor node and its nodular elements in the fibrovascular stroma it was possible to identify alpha-fetoprotein expression, CD34, nuclear and cytoplasmic expression of beta-catenin, CDX2, as well as a rare expression of PLAP and multi-cytokeratin, and mitotic activity was high (21 in 10 high power fields, 400x magnification). In the existing literature available to us, there is only one observation of combined hepatoblastoma and yolk sac tumor. Parents patients agreed to use personal data, including the fotos, in research and publications.
