The 1997 International Germ Cell Consensus Classification [17] is a tool for estimating the risk of relapse after treatment of malignant germ-cell tumor. A small study of ovarian tumors in girls [18] reports a correlation between cystic and benign tumors, and conversely, solid and malignant tumors. Because the cystic extent of a tumor can be ...
Choriocarcinoma is a malignant, trophoblastic [ 1 ] cancer, usually of the placenta. It is characterized by early hematogenous spread to the lungs. It belongs to the malignant end of the spectrum in gestational trophoblastic disease (GTD). It is also classified as a germ cell tumor and may arise in the testis or ovary.
Contents. Testicular cancer. 7.4 × 5.5-cm seminoma in a radical orchiectomy specimen. Testicular cancer is cancer that develops in the testicles, a part of the male reproductive system. [ 2 ] Symptoms may include a lump in the testicle or swelling or pain in the scrotum. [ 2 ] Treatment may result in infertility.
Males with pure embryonal carcinoma tend to have a normal amount of the protein alpha-fetoprotein in the fluid component of their blood. The finding of elevated amounts of alpha-fetoprotein is more suggestive of a mixed germ cell tumour, with the alpha-fetoprotein being released by the yolk sac tumour component. [citation needed]
Relative incidences of testicular tumors, showing seminoma at bottom left. [2] A seminoma is a germ cell tumor of the testicle or, more rarely, the mediastinum or other extra-gonadal locations. It is a malignant neoplasm and is one of the most treatable and curable cancers, with a survival rate above 95% if discovered in early stages.
Endodermal sinus tumor (EST) is a member of the germ cell tumor group of cancers. [1] It is the most common testicular tumor in children under three, [2] and is also known as infantile embryonal carcinoma. This age group has a very good prognosis. In contrast to the pure form typical of infants, adult endodermal sinus tumors are often found in ...
Germ cell tumor is a rare cancer that can affect people at all ages. As of 2018, germ cell tumors account for 3% of all cancers in children and adolescents 0–19 years old. [22] Germ cell tumors are generally located in the gonads but can also appear in the abdomen, pelvis, mediastinum, or brain. Germ cells migrating to the gonads may not ...
Pathology, urology. Germ cell neoplasia in situ (GCNIS) represents the precursor lesion for many types of testicular germ cell tumors. [1] The term GCNIS was introduced with the 2016 edition of the WHO classification of urological tumours. [1] GCNIS more accurate describes the lesion as it arises between the basement membrane and Sertoli cells ...
