Organization consisting of a variety of tumor
Some tumors in real terms by two or more different types of tissue, known as mixed tumor. The most complex mixed teratoma is a tumor, tumor-in real terms from the three germ layers from the various organizations mixed composition, like a deformed fetus. There embryonic kidney tumor is relatively a variety of tumors. Carcinosarcoma is also a kind of mixed tumor. Are as follows:

1. Teratoma (teratoma)

Teratoma is derived from how to divide the potential of germ cell tumors often contain a wide range of the three germ layers of the composition, structure of the arrangement disorder. According to its appearance can be divided into two types of cystic and solid: According to the differentiation of different maturity, can be divided into benign and malignant teratoma teratoma II. The most common tumor in the ovary and testis. Can be seen even in the mediastinum, sacrococcygeal, peritoneum, the pineal gland, and other parts.

(1) benign teratoma: cystic for more, it is also known as cystic teratoma, or dermoid cysts, found in the ovary. Tumor for more than a single room, for the particle-wall, rough, often nodular uplift. Sometimes to see small pieces of bone, cartilage, and so on, there are sebaceous cysts, hair, even teeth can be seen. Endoscopic, with the exception of skin and skin see the annex, could also see the follow-up to the cubic epithelial glands, trachea, or intestinal, bone, cartilage, brain, muscle, thyroid, and other organizations. Basically, differentiation and maturation of various organizations, it is called a mature teratoma. Teratoma benign prognosis is good, hateful to a small number of squamous cell carcinoma.

(2) malignant teratoma: more physical, more common in the testes than in ovaries. The main differentiation from immature embryonic tissue, there is a common neuroectodermal differentiation of non-performing components, so-called immature teratoma. The tumor often transfer, the transfer of pelvic and distant organs.

2. Embryonic kidney tumor (embryonic tumor of kidney), also known as Wilms tumor (nephroblastoma), Wilms tumor. By the residual renal immature embryos developed from the organization, mostly in children under five years old. Various components of the tumor, in addition to see the tumor cells were arranged in the nest-like mission to form a naive or renal tubular-like structure, interstitial osteoporosis can be seen in the mucus-like organizations, can sometimes see the striated muscle, cartilage, bone or adipose tissue ( Details, see Chapter 12).

3. Carcinosarcoma (carcinosarcoma) in the same tumor have cancer and sarcoma components are known as sarcoma cancer. Cancer of the ingredients for squamous cell carcinoma, transitional cell carcinoma, adenocarcinoma, poorly differentiated cancer, and so on; sarcoma can be divided into components of fibrosarcoma, leiomyosarcoma, rhabdomyosarcoma, osteosarcoma, chondrosarcoma, and so on. Sarcoma cancer and the ratio of different components can be mixed, often carcinoma and sarcoma with the kind of ingredients, more than one occasion, such as cancer and leiomyosarcoma and mixed osteosarcoma. Sarcoma cancer can occur in various forms, such as epithelial and mesenchymal malignant simultaneously, multipotent stem cells to cancer and sarcoma direction of the two types of differentiation; cancer induced malignant transformation took place during mass; part of the cancer cells took place between the organizations, chemical and biological weapons and malignant change leaf, and so on .
