Mixed Germ Cell Tumor

Abstract Mixed germ cell tumor (MGCT) mainly occurs in young women’s ovaries and men’s testicles and rarely occurs outside the gonad. Fewer than 10 cases of mediastinal MGCT are available in PubMed, Embase, and other databases in English, while mediastinal MGCT with three pathological components, such as yolk sac tumor, immature teratoma, and embryonal carcinoma, has not been reported previously. A 12-year-old male sought medical attention for chest discomfort and underwent a computed tomography (CT) scan. A large soft tissue mass occupying most of the left thoracic cavity and mediastinum was detected. A CT-guided biopsy was performed, and an MGCT was diagnosed with pathological components, including yolk sac tumor, immature teratoma, and a small amount of embryonal carcinoma. Due to the large size of the tumor, the patient was treated with an EP regimen (etoposide + cisplatin) and paclitaxel + ifosfamide + cisplatin interstitial chemotherapy. The patient was followed up for 6 months and was alive with the disease. To the best of our knowledge, this is the 10th patient with MGCT in the mediastinum. The incidence of mediastinal MGCT is low, but it should still be considered one of the differential diagnoses of isolated pleural fibroma and neurogenic tumors.

Background: Mediastinal germ cell tumors are uncommon, representing less than 1% of all malignancies. They mostly occur in young men after puberty and have a poor prognosis with over all long term survival rate 42%. Case Report: We reported a case report in Saiful Anwar Malang Hospital, Indonesia, a young man, 26 years old with an anterior mediastinum tumor and VCSS The CT scan of the chest showed an anterosuperior mediastinal mass which compress the superior vena cava. The result from transthoracic FNAB with USG guidance showed an extragonadal germ cell tumor which resemble an Embryonal Carcinoma from mediastinum. The AFP serum level was elevated. Patient underwent a radiotherapy and a surgical debulking. The biopsy showed an Endodermal Sinus Tumor (Yolk Sac). Immunohistochemical stain for cytokeratin was positive in the tumor cells while stain for CD30 was negative. These were confirming the diagnosis of primary mediastinal yolk sac tumor. Patient received a combination chemotherapy for a total 6 cycles. Conclusion: Some procedures like biopsy, tumor marker, immunohistochemical stain, could differentiate the subtype of mediastinal germ cell tumor. The multimodality treatment by combining chemotherapy with surgical therapy or radiotherapy could increase the survival outcome of patients.

Childhood Malignancies

Introduction: Germ cell tumors are a group of tumors with different clinical presentation and histological and biological characteristics. Malignant germ cell tumors occur at all ages with a trend of bimodal distribution in infancy and adolescence. Objective: To evaluate the demographic characteristics, distribution of different types of germ cell tumor, treatment modalities and outcome of germ cell tumor in children in a tertiary care hospital of Bangladesh. Methods: In this retrospective study, data regarding age and sex distribution, location, types of tumors, management of germ cell tumor in children were retrieved from the medical records of pediatric oncology department in NICRH, Dhaka from 2008 to 2014. Results: Out of total 87 patients female were 50 and male 37. Most of the patients were up to 5 years of age. The gonadal germ cell tumors (80%) were more than extragonadal tumor (20%) in both male and female patients. The most common germ cell tumor was dysgerminoma (32%) followed by yolk sac tumor (29.8%) and teratoma (19.5%). Yolk Sac Tumor (51.4%) was the most common in male and dysgerminoma (56%) the commonest in female. Out of 87, seventy two (82.7%) received chemotherapy following surgery. Among those 72 patients who received chemotherapy 49 (68 %) patients completed their treatment. Until the last follow up 71.4% patients remained alive and tumor free. Conclusion: Germ cell tumors are the most variable tumor of all childhood malignancies that has difference in age, sex, location and histological subtypes. Gonadal tumors have better prognosis than extragonadal tumors in both the sex. DS (Child) H J 2019; 35(2) : 119-122

Prognosis Group

The authors report a rare case involving the occurrence of metachronous pure germinomas long after treatment of a mixed germ cell tumor (GCT) categorized as having a poor prognosis. A neurohypophysial germinoma occurred 4 years and 6 months after the initial treatment of a mixed pineal GCT containing a yolk sac tumor and a germinoma. Furthermore, intramedullary germinomas occurred 21 years after the initial treatment of the mixed GCT and 15 years after the second treatment of the neurohypophysial germinoma. The neurohypophysial germinoma was not confirmed histopathologically, but the intramedullary germinoma was histopathologically diagnosed as a pure germinoma. Serum α-fetoprotein levels at the second neurohypophysial and third intramedullary occurrences of the germinomas were less than 10 ng/ml. Therefore, no yolk sac components seemed to be contained in the tumors. The second neurohypophysial and third intramedullary germinomas might be recurrences of the germinoma component of the pineal mixed GCT, which consisted of a yolk sac tumor and a germinoma. However, it seems very unlikely that only the germinoma, categorized in the good prognosis group, would be the only one to recur. Hence, it seems plausible that both the second and the third occurrences of pure germinoma were de novo metachronous GCTs arising after the pineal mixed GCT was cured. The authors' case indicates the possibility of multicentric GCTs in the CNS.

Malignant Germ Cell Tumor

Yolk sac tumor called endodermal sinus tumor, is a rare and very malignant germ cell tumor. The second largest ovarian germ cell tumor after dysgerminoma, with an incidence of 1% of ovarian malignancies. Tumors usually appear as fast-growing masses in young women. The radiological imaging of this tumor is seen as a large dense cystic mass with heterogeneous enhancement, a component of dilated intratumoralblood vessels accompanied by an intralesional hemorrhagic focus. The best radiological modality is CT scan or MRI. CT imaging useful for distinguishing yolk sac tumors from other ovarian tumors. In this article was reported a case of ovarial york sac tumor in 7 years old girl. USGand CT scan examination showed solid with cystic mass in the pelvic cavity. Histologically was malignant germ cell as york sac tumor.

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.
