A testicular teratoma may present as a painless lump. [1] Complications may include ovarian torsion, testicular torsion, or hydrops fetalis. [1] [2] [3] They are a type of germ cell tumor (a tumor that begins in the cells that give rise to sperm or eggs). [4] [8] They are divided into two types: mature and immature. [4]
The initial treatment for testicular cancer is surgery to remove the affected testicle (orchiectomy). While it may be possible, in some cases, to remove testicular cancer tumors from a testis while leaving the testis functional, this is seldom done, as the affected testicle usually contains pre-cancerous cells spread throughout the entire testicle.
This treatment option is an alternative to remove testicular cancer masses which are <20 mm, have a high probability of being benign, and with negative serum tumor markers. Its benefits include preserving fertility and normal hormone function. [7] About half of testicular cancer germ cell tumors are seminomas. Individuals with seminomas are 80 ...
A teratoma is a tumor of germ cell origin, containing tissues from more than one germ cell line, [2] [3] [4] It can be ovarian or testicular in its origin. [4] and are almost always benign. [5] An immature teratoma is thus a very rare tumor, representing 1% of all teratomas, 1% of all ovarian cancers, and 35.6% of malignant ovarian germ cell ...
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.
Spermatocytic tumor is a rare tumour, making up only one to two percent of all testicular germ cell tumours. Men presenting with this tumour are generally 50 to 60 years old, and its occurrence is rare in men under 30 years old. Most present with slow, painless testicular enlargement, which may involve both testes. [1]
Germ cells tumors constitute a vast majority of the incidences of testicular tumors. [3]GCTs are classified by their histology, [4] regardless of location in the body. . However, as more information about the genetics of these tumors become available, they may be classified based on specific gene mutations that characterize specific tu
Teratoma Although teratoma is the second most common testicular tumor in children, it affects all age groups. Mature teratoma in children is often benign, but teratoma in adults, regardless of age, should be considered malignant. Teratomas are composed of all three germ cell layers, i.e. endoderm, mesoderm and ectoderm. At ultrasound, teratomas ...
