Testicular germ cell tumors are divided into two groups, seminomas and non- seminomas being subdivided further into 4 distinct histologies (yolk sac tumor,.

Sep 1, 2019 Most germ cell tumours occur in the testicals (male gonads) or in the ovaries BACKGROUND: Nonseminomatous germ cell tumors (NSGCTs)

Although they are made up of distinct histological entities, in general, they have similar radiographic appearances. Nonseminomatous germ cell tumors are cancerous tumors commonly found in the pineal gland in the brain, in the mediastinum, or in the abdomen. They originate from cells that were meant to form sex cells (i.e., sperm or eggs). Non-Seminomas. This type of germ cell tumor usually occurs in men between their late teens and early 40s.

Mixed Germ Cell Tumor Regressed Germ Cell Tumors Germ cell tumors that have undergone either partial or complete regression (“burnt-out”), leaving behind a well-delineated nodular focus of scaring fibrosis in the testis. Can present with metastatic disease, but primary has completely regressed. Can be seminoma or Non-seminoma. About 95 percent of testicular cancers begin in germ cells, specialized cells in the testicles that make sperm.While these tumors typically start in the testicles they also occasionally arise in the abdomen, chest, or other areas of the body, even if there’s no evidence of cancer in or near the testicles.

Non-seminomas These types of germ cell tumors usually occur in men between their late teens and early 30s. The 4 main types of non-seminoma tumors are embryonal carcinoma, yolk sac carcinoma, choriocarcinoma, and teratoma.
