Yolk Sac Tumors

Yolk sac tumors, the most common germ cell tumor in young infants and children, however, are distinctly uncommon site in the vagina. A baby with bleeding per vaginum since one month presented at 9 months of age with raised Serum α- fetoprotein (AFP) but normal levels of ß-HCG and CA-125 is reported. Fine needle aspiration from the mass yielded material suggestive of a germ cell tumor. The histopathological findings further confirmed the diagnosis of a yolk sac tumor.

Yolk Sac Tumors

Extragonadal yolk sac tumors are uncommon and usually seen in sacrococcygeal, mediastinal, intracranial, and retroperitoneal sites. Yolk sac tumors of the head and neck region are rare, and the few reported cases have arisen in neonates or infants in conjunction with a teratoma or other germ cell tumor subtypes. We report a unique case of a pure yolk sac tumor presenting as a primary lesion in the right thyroid lobe of a 10-year-old girl. The diagnosis was suspected after fine-needle aspiration, and extensive sampling of the thyroidectomy specimen revealed no teratoma or other germ cell tumor. Serum α-fetoprotein levels were markedly elevated 6 days after excision, and imaging disclosed numerous bilateral pulmonary nodules suggestive of metastatic disease but did not reveal a mediastinal mass. The tumor has shown a favorable response to bleomycin, etoposide, and cisplatin chemotherapy. To the best of our knowledge, this is the 1st description of a primary pure yolk sac tumor of the thyroid.

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.

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.

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.

9002 Background: To describe the clinical outcome of children with metastatic GCT (stage IV) at diagnosis according to the primary metastatic site(s). Methods: From March 1990 to February 1996, 299 children and adolescents with stage III/IV gonadal and stage I-IV extragonadal GCT were eligible for a Pediatric Intergroup high-risk (HR) GCT trial. Patients were randomized to receive 4–6 courses of cisplatin (P) standard dose [ 20 mg/m2/day (d) × 5] or high-dose (HDP) [40 mg/m2/d × 5] with etoposide (E) 100 mg/m2/d × 5 and bleomycin (B) 15 mg/m2 on d1. We retrospectively investigated the outcome of patients with stage IV and compared their outcome according to metastatic site(s). Results: There were 133 patients with stage IV disease. The median age was 2.6 years (y) [range, 3 d-19.3 y], 70 were female. Primary sites included: 43 testicular, 14 ovarian, 76 extragonadal (45 sacroccocygeal, 28 mediastinal, 3 other). Histologies included: 66 pure yolk sac tumors, 21 immature teratomas and yolk sac tumors, 26 mixed germ cell tumors, 7 pure germinoma/seminoma/dysgerminomas, 1 immature teratoma with a non-classic germ cell tumor, 2 mixed germ cell tumor admixed with a nonclassic germ cell tumor, 5 pure choriocarcinomas, and 5 patients with unknown histology. There were no statistically significant differences in the 5-year EFS or OS rates by site of metastases. Of the 19 patients with either bone or brain involvement, 17 patients had bone and 3 had brain metastases. Conclusion: The outcome for patients with metastatic GCT is excellent with contemporary cisplatin-based regimes and is independent of the site of metastatic disease.

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.

AbstractGerm cell tumors of the central nervous system (CNS) are usually located along the midline. Yolk sac tumor is a rare germ cell tumor very uncommonly located outside the midline, and, in such cases, it can be mistaken with other primary tumors. We report a case of a 32-year-old male patient who presented with a right temporal lobe tumor suggestive of a high grade glioma. He was submitted to a right temporal lobectomy with complete tumor removal. The histological exam revealed a germ cell tumor (later confirmed to be a yolk sac tumor). The search for a primary tumor outside of the CNS (including a positron emission tomography scan) was negative, making this a primary temporal lobe yolk sac tumor. The patient was submitted to chemotherapy and radiotherapy, but died 7 months after the surgery.
