Germ cell tumors represent only 20% to 25% of all benign and malignant ovarian neoplasms. Mixed germ cell tumors are a rare variety of non–dysgerminomatous germ cell tumors. They contain two or more elements; the most frequent combination being a dysgerminoma and an EST (Endodermal Sinus Tumor). We present a case of malignant mixed germ cell tumor comprising of yolk sac tumor, embryonal carcinoma and choriocarcinoma. A 13-year-old girl presented with a huge 25 x 18 cm mass in abdomen with raised values of CA-125, hCG, AFP (alpha-feto protein) and LDH (lactate dehydrogenase). She underwent laparotomy followed by unilateral salpingoopherectomy and infracolic omentectomy. Histopathology report revealed malignant mixed germ cell tumor comprising predominantly of EST with elements of embryonal carcinoma and non-gestational choriocarcinoma. Following surgery, she was started on adjuvant chemotherapy (Bleomycin, Etoposide and Cisplatin regimen). Mixed germ cell tumor (YST/EST, non-gestational choriocarcinoma and embryonal carcinoma) is a very rare tumor. Careful initial surgery with adequate staging biopsies followed by combination chemotherapy can greatly improve the prognosis of these patients

Mixed Germ Cell Tumor

Adult extrarenal nephroblastoma is a very rare tumor. Nephroblastoma arising from primary testicular germ cell tumor is exceedingly rare. To our knowledge, only three cases have been reported in the English literature. We report a case of a 19-year-old man who presented with a large right testicle. Image studies showed a large retroperitoneal mass along with liver and lung metastases. Orchiectomy demonstrated a mixed germ cell tumor composed of yolk sac tumor, embryonal carcinoma, and mature and immature teratoma with a significant portion of nephroblastoma. The patient received chemotherapy and no recurrence was noted during six months of followup. WT-1 expression was also studied due to the lack of consistency of its expression in testicular nephroblastoma in the literature. We also present a discussion and review of the literature due to its rarity, which indicate an adverse prognosis for patients with nephroblastoma components receiving standard chemotherapeutical regimes for testicular germ cell tumors.

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.

Primary testicular germ cell tumors (PGCT) can be classified as seminomatous and non-seminomatous germ-cell tumor (NSGCT) types. Mixed germ cell tumors (MGCT), a subtype of NSGCT, contain more than one germ cell components. Here, we present a rare case of a MGCT composed of yolk sack tumor and teratoma which had a continuous large abdominal and retroperitoneal extension. A 43 years old male presented with complaints of discomfort and swelling over the right inguinoscrotal region. Ultrasonography (USG) showed a large ill-defined heteroechoic mass in the right inguinoscrotal region with vascularity and without separate visualization of right testis. Subsequent contrast enhanced Computed Tomography (CT) showed large enhancing mass in the right scrotal sac which was continuous with large abdominopelvic and retroperitoneal mass through the right inguinal canal. Tru-Cut biopsy of the scrotal mass showed MGCT with yolk sac and teratoma component. Patient underwent 6 cycles of chemotherapy followed by Right Radical Inguinal Orchidectomy.

We report the case of a 17-year-old male with a testicular tumor and high serum levels of α-fetoprotein. The patient was treated with surgery followed by combination chemotherapy with bleomycin, etoposide, and cisplatin. Histologic examination showed features of a mixed germ cell tumor composed of mature teratoma, immature teratoma, embryonal carcinoma, yolk sac tumor, and polyembryoma. He is currently well, and his serum levels of α-fetoprotein have been normal more than 5 months after treatment. His brother, aged 17 years at the time, had a similar tumor removed from the right testicle 5 years previously.

Mixed Germ Cell Tumor

Cryptorchidism is the most common predisposing factor in the development of testicular germ cell tumors. Seminoma is the most common malignancy developing in a cryptorchid testis. A rare case of seminoma with mixed germ cell tumor in an undescended testis is reported here. A 35-year-old male patient presented with swelling in left inguinal region science 1.5year. This  was smooth, firm to hard in consistency, restricted mobility and his left scrotum was empty. Serological markers α-FP, β-HCG, LDH were raised.  Sonography and CT scan revealed a testicular tumor in undescended left inguinal testis. High inguinal orchidectomy was done. Patient had an uneventful recovery. The histopathology report of biopsy revealed a seminoma with mixed germ cell tumor. Early diagnosis and management of the undescended testicle are needed to preserve fertility and improve early detection of testicular malignancy. Therapy should begin between six months and two years of age and may consist of hormone or surgical treatment.

Initial Surgery

Ovarian germ cell tumours comprise approximately 15% to 20% of all ovarian neoplasms. In pregnant females, its incidence is very low. They arise from primordial germ cells derived from the embryonal gonad. Malignant germ cell tumours comprise less than 5% of all ovarian neoplasms. Most malignant ovarian neoplasms in pregnant women are at early stages and are associated with good prognosis both for the mother and for the neonate. Histologic subtypes and prognosis do not differ from tumors not associated with pregnancy. Careful initial surgery with adequate staging biopsies followed by combination chemotherapy can greatly improve the prognosis of these patients. We present a case of malignant mixed germ cell tumor in a pregnant female who presented with abdominal mass after delivering a normal child. Histological and biochemical tumour markers confirmed it to be malignant mixed germ cell tumor.

History Of

A 5-y-old backyard Araucana–Americana rooster was presented to the regional diagnostic laboratory with a history of progressive lethargy and respiratory signs. Autopsy revealed a single large mass of testicular origin in the coelomic cavity, causing compression of other organs. Histologically, the mass was 1 neoplasm with mixed components of 2 different germ cell tumors, namely a teratoma composed of elements of all 3 primordial germ cell lines (ectoderm, mesoderm, and endoderm), and a seminoma consisting of round or polygonal cells arranged in sheets supported by a scant fibrovascular stroma. Teratomas and seminomas are both considered to be uncommon neoplasms in poultry medicine. A testicular teratoma is composed of mature embryonic tissue derived from at least 2 of the 3 germinal layers. Seminomas and teratomas both arise from the germinal epithelium of seminiferous tubules and are classified as germ cell tumors. This neoplastic mass thus is a rare case of a mixed germ cell tumor.

Subtotal Removal

Intracranial nongerminomatous germ cell tumors (NGGCTs) in unusual locations are extremely rare. Here, we report a case of a yolk sac tumor in the frontal lobe in a middle-aged patient. A 42-year-old man was admitted to our hospital for headache and nausea. Magnetic resonance imaging (MRI) showed an enhanced mass lesion with a marked cyst component. The serum alpha-fetoprotein (αFP) level was extremely high. Histological examination of specimens after subtotal removal revealed a primary mixed germ cell tumor with extensive yolk sac tumor elements, often referred to as an intracranial “yolk sac tumor.” The preoperative diagnosis of NGGCTs in unusual age and locations is extremely difficult. Clinicians should consider the possibility of NGGCTs, including yolk sac tumors, when intracranial tumors with unusual MRI findings are encountered.

Background: Germ-cell tumors (GCT) are the commonest ovarian neoplasm in the first two decades of life. Aim: To study the profile of ovarian GCT in children and their outcome. Methods: Retrospective study of all cases of malignant ovarian GCT in the pediatric age (up to 18 years) was done from January 2002 to December 2015. The medical records of all admitted cases during this period were reviewed and the data was analysed with respect to age at diagnosis, clinical presentation, tumor markers, surgical stage, tumor histology, therapy, clinical course, and outcome. Results: Girls with malignant ovarian GCT were seen at our institute during the study period. Out of these 25 underwent treatment. Mean age at presentation was 11.7 years (range: 3-18 years). Abdominal pain was the commonest presentation. Twelve (47.3%) had right sided disease, 11 (42%) had left sided disease and 2 had bilateral disease. Twelve cases (57.8%) were diagnosed as stage I disease, 5 (10.5%) as stage II, 7 (26.3%) as stage III and 1 (5.2%) as stage IV. Elevated AFP >1000 was found in 9 (47.3%), elevated B-HCG (>50) in 7 (42%) and elevated LDH (>1000) in 7 (36.8%) patients at presentation. Twenty (73.6%) patients underwent surgery prior to chemotherapy out of which 4 (21%) patients presented after undergoing surgery at other centre. Fourteen (57.8%) patients received 4 cycles of BEP based chemotherapy, 6 (21%) received 3 cycles, 2 (10.5%) received 2 cycles and 1 patient did not receive any chemotherapy as it was mature teratoma. The most common histology was dysgerminoma in 8 (42%) patients followed by mixed germ cell tumor in 4 (21%), teratoma in 3 (15.7%), embryonal carcinoma in 2 (10.5%) and yolk sac tumor and mature teratoma in 1 patient each. Four (21%) patients had relapse on contralateral side which was salvaged. 1 patient presented with relapse who underwent only surgery outside, 1 patient had ovarian torsion. Median follow up is 27months. The event free survival rate was 78.9%. Conclusion: This study confirms an excellent outcome for girls with ovarian germ cell tumor. Patients with advanced surgical stage relapsed frequently. The mainstay of treatment is fertility preserving surgery and cisplatin-based chemotherapy.
