The mediastinum is the most common site of primary extragonadal germ cell tumors (GCTs), which represent approximately 10–15% of mediastinal tumors. 1 It has been suggested that these tumors are derived from primitive germ cells that migrate aberrantly along the urogenital ridge during early embryogenesis. 2 With the exception of prognosis, the primary malignant mediastinal non‐seminomatous germ cell tumor (MMNSGCT) shares several features with its gonadal counterpart, such as similar
They originate from cells that were meant to form sex cells (i.e., sperm or eggs). Non-seminomatous germ cell tumors can be divided histologically into: embryonal cell carcinoma : rare choriocarcinoma : rare (carries worst prognosis) yolk sac tumor teratoma: accounts for 5-10% of germ cell tumors mature immature teratoma with malignant transformation mature immature teratoma with Nonseminomatous Germ Cell Tumors NSGCT are very variable in appearance and prognosis. There are four main types of NSGCT that can appear alone, but most often appear as a “mixed” NSGCT, with more than one type present: The nongerminomatous or nonseminomatous germ-cell tumors (NGGCT, NSGCT) include all other germ-cell tumors, pure and mixed. The two classes reflect an important clinical difference.

More than 95% of testicular tumors arise from the germ cells. Testicular germ cell tumors can be subdivided into two major groups: seminoma and non-seminomatous germ cell tumors (NSGCTs). The vast majority of NSGCTs contain a mixture of two or more histologic patterns, known as mixed germ cell tumor.

Surgery for postchemotherapy residual nonseminomatous germ cell tumors may be difficult due to exceptional lesion size and location. Case presentation. A 47‐year‐old man presented with swelling and pain in the left scrotum. Computed tomography revealed a solid occupied lesion in the left scrotum with huge metastases in the left lung and pleura.
Additionally, AFP can be useful in differentiating seminomatous germ cell tumors from nonseminomatous germ cell tumors in that the former does not produce AFP.

Tumors 20 to 30 cm in diameter can exist with minimal symptomatology. Rare cases of adult onset acute megakaryoblastic leukemia are associated with malignant mediastinal germ cell tumor. In these cases, the mediastinal germ cell tumor develops before or concomitantly with but not after acute megakaryoblastic leukemia.

1 dag sedan · There are two main types of GCT: seminoma and nonseminomatous germ cell tumors (NSGCT). Both seminoma and NSGCT occur at about the same rate, and men can have seminoma, NSGCT or a combination of both. There are several differences between seminomas and NSGCT, but the initial distinction is based on how the tumor looks under the microscope.

Fig. 4. Flow chart depicting a novel technique with which to mana - "Brain angiometastasis from a non-seminomatous germ cell tumor: A case report"
We report a case of complete pathological remission of a patient with advanced non-seminomatous germ cell tumor in intra-abdominal testis by primary chemotherapy alone, with a review of the literature. Patients with primary mediastinal nonseminomatous germ-cell tumors or tumors with late relapse (>2 years after previous therapy) were not offered high-dose chemotherapy during the specified period. Brain metastases from non-seminomatous germ cell tumors (NSGCTs) are rare and mainly occur in young men whose clinical condition is unimpaired. The records of 15 patients with brain metastasis from non-seminomatous germ cell tumors of the testis, who had been surgically treated between 1984 and 1998, were retrospectively reviewed.

Non-germinomatous germ cell tumors are also called “secreting tumors” because they may secrete alpha-fetoprotein (a protein produced during pregnancy) or a hormone called human chorionic gonadotropin (hCG).

The mediastinum is the most common site of primary extragonadal germ cell tumors (GCTs), which represent approximately 10–15% of mediastinal tumors. 1 It has been suggested that these tumors are derived from primitive germ cells that migrate aberrantly along the urogenital ridge during early embryogenesis. 2 With the exception of prognosis, the primary malignant mediastinal non‐seminomatous germ cell tumor (MMNSGCT) shares several features with its gonadal counterpart, such as similar DISCUSSION: Extragonadal non-seminomatous germ cell tumors (NSGCTs) primarily affect men during the third and fourth decades of life and are more aggressive than their seminomatous counterpart. Majority of patients with mediastinal NSGCTs are symptomatic at the time of diagnosis, with chest pain, hemoptysis, cough, fever, or weight loss.
