Klinefelter syndrome (KS), also known as 47,XXY, is a chromosome anomaly where a male has an extra X chromosome. [10] These complications commonly include infertility and small, poorly functioning testicles (if present). These symptoms are often noticed only at puberty, although this is one of the most common chromosomal disorders, occurring in ...
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.
Specialty. Oncology. An immature teratoma is a teratoma that contains anaplastic immature elements, and is often synonymous with malignant teratoma. [1] 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]
The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body. [1] Not all tumors or lumps are cancerous; benign tumors are not classified as being cancer because they do not spread to other parts of the body. [1]
Immature teratoma is the malignant counterpart of the mature teratoma and contains immature tissues which typically show primitive or embryonal neuroectodermal histopathology.

In most cases, the process is normal in every aspect except the unusually early age and simply represents a variation of normal development. There is early development of secondary sex characters and gametogenesis also starts earlier.
The cancer stem cell model, also known as the Hierarchical Model proposes that tumors are hierarchically organized (CSCs lying at the apex [6] (Fig. 3).) Within the cancer population of the tumors there are cancer stem cells (CSC) that are tumorigenic cells and are biologically distinct from other subpopulations [7] They have two defining features: their long-term ability to self-renew and ...
