The naming and classification of tumor
First, the principle of naming the tumor

The human body in any part of any organization, can occur in almost any organ tumors, so a wide variety of tumors, also named complex. According to its general organization that is the source of the organization named. In its benign source of the name of the organization after the "tumor", such as connective tissue fibers from a benign tumor known as fibroids (fibroma), from the benign glandular tumor called adenomas (adenoma), and so on. Sometimes combined with morphological characteristics of the tumor name, as were papillary adenoma growth and the formation of cysts are known as the emulsion-like head cystadenoma. Cancer in general is also in accordance with its organization named sources. Epithelial tissue from the general term for cancer (carcinoma), naming its source in the name of the organization after the "cancer", such as from the squamous cell cancer called squamous cell carcinoma, adenoid was derived from glandular structure The cancer is called adenocarcinoma, and so on. From the mesenchymal (connective tissue, including fiber, fat, muscle, vascular, bone, cartilage, etc.) are collectively referred to as the occurrence of malignant sarcoma (sarcoma), naming its source in the organization after the name of "sarcoma", such as fiber Sarcoma, rhabdomyosarcoma, osteosarcoma, and so on. The malignant form has certain characteristics, and then combine the characteristics of the form and name, such as the formation and cystic papillary carcinoma of the structure, known as papillary cystadenocarcinoma. If a cancer tumor in both the structure and the structure of the sarcoma, the cancer known as sarcoma (carcinosarcoma).

In pathology, cancer is the source of the malignant epithelial tissue, but most people the word "cancer" (cancer), often used to refer to all the malignant tumors.

A small number of non-malignant tumors according to the principles of the above-mentioned names, such as from some naive and nerve tissue of cancer called medulloblastoma, such as neuroblastoma, medulloblastoma, Wilms tumor, and so on; some cancer complicated As the old habit or, in the name of the tumor before the "vicious", such as abnormal cell malignant tumor, malignant lymphoma, malignant melanoma, and so on. Some of malignant tumors known names, such as Ewing (Ewing) tumor, Hodgkin (Hodgkin) disease; or tumor cells form name, such as giant cell tumor of the bone, the lung cancer cells Yan table. As for leukemia, cancer spermatogonia are accustomed to using the name of a small number of malignant tumors, although referred to as "tumor" or "disease" are, in fact, malignant tumors.

Second, the classification of tumors

The classification of tumors usually occur in their organizations (that is, from what organizations) on the basis of each category is divided into two major categories of benign and malignant. Examples are as follows (Table 7-2).

Table 7-2 classification of tumors, for example

Source organizations
  Benign
  Malignant
  Good site
 
First, epithelial tissue
 
Squamous cell
  Papilloma
  Squamous cell carcinoma
  Papilloma found in the skin, nose, sinuses, throat, etc.; found in squamous cell carcinoma of the cervix, skin, esophagus, nasopharynx, lung, throat and penis, etc.
 
Basal cell
  Basal cell carcinoma
  Head and face skin
 
Glandular
  Adenoma
  Adenoma (all types)
  Adenomas found in the skin, thyroid, stomach, intestine; adenocarcinoma found in the stomach, intestines, breast, thyroid, etc.
 
Serous or mucinous cystadenoma
  Serous or mucinous cystadenocarcinoma
  Ovarian
 
Pleomorphic adenoma malignant pleomorphic adenoma
  Salivary gland
 
Transitional cell
  Papilloma
  Transitional cell carcinoma
  Bladder, renal pelvis
 
Second, mesenchymal
 
Fibrous connective tissue
  Fibroids
  Fibrosarcoma
  Limbs
 
Fibrous
  Fibrous
  Malignant fibrous histiocytoma
  Limbs
 
Adipose tissue
  Lipoma
  Liposarcoma
  The former was particularly prevalent in the subcutaneous tissue, which was particularly prevalent in the lower limbs and retroperitoneal
 
Smooth organization
  Leiomyoma
  Leiomyosarcoma
  Uterine and gastrointestinal
 
Organization of striated muscle
  Rhabdomyoma
  Rhabdomyosarcoma
  Sarcoma was particularly prevalent in the head and neck, limbs and reproductive tract
