Rarely, choriocarcinoma occurs in primary locations other than the placenta; very rarely, it occurs in testicles. Although trophoblastic components are common components of mixed germ cell tumors, pure choriocarcinoma of the adult testis is rare.
Teratocarcinoma refers to a germ cell tumor that is a mixture of teratoma with embryonal carcinoma, or with choriocarcinoma, or with both. [9] This kind of mixed germ cell tumor may be known simply as a teratoma with elements of embryonal carcinoma or choriocarcinoma, or simply by ignoring the teratoma component and referring only to its ...
Testicular cancer is highly treatable and usually curable. [5] Treatment options may include surgery, radiation therapy, chemotherapy, or stem cell transplantation. [2] Even in cases in which cancer has spread widely, chemotherapy offers a cure rate greater than 80%. [4] Globally testicular cancer affected about 686,000 people in 2015. [6]
Choriocarcinoma --- Choriocarcinoma is a highly malignant testicular tumor that usually develops in the 2nd and 3rd decades of life. Pure choriocarcinomas are rare and represent only less than 1 percent of all testicular tumors.
This tumour produces Leydig cells, which normally are found in the testicle and tend to secrete androgens. Sertoli–Leydig cell tumour. This tumour produces both Sertoli and Leydig cells. Although both cell types normally occur in the testicle, this tumour can occur in the ovary. [1] Gynandroblastoma. A very rare tumour producing both ovarian ...
College student, 20, felt soreness in groin, thought it was pulled muscle. It was 1st sign of testicular cancer. He's now cancer free.
Microscopic examination of affected testicular tissue most commonly shows germ cells with enlarged hyperchromatic nuclei with prominent nucleoli and clear cytoplasm. These cells are typically arranged along the basement membrane of the tubule, and mitotic figures are frequently seen.
In the testis pure embryonal carcinoma is also uncommon, and accounts for approximately ten percent of testicular germ cell tumours. However, it is present as a component of almost ninety percent of mixed nonseminomatous germ cell tumours. The average age at diagnosis is 31 years, and typically presents as a testicular lump which may be painful.
