Study Notes
Neoplasia Terminology
- 'Neoplasia' literally means 'new growth' or 'new formation,' referring to abnormal tissue growth.
Benign Neoplasms
- Benign neoplasms originating from epithelial tissues are named with the suffix ‘-oma.’
- An example includes adenoma, which arises from glandular tissue.
Glandular Neoplasms
- A benign epithelial neoplasm forming a glandular pattern is called an "adenoma."
Malignant Neoplasms
- A malignant neoplasm arising from mesenchymal tissue is termed "sarcoma."
Nonneoplastic Misnomers
- An example of a nonneoplastic misnomer is a "fibroma" which can sometimes refer to benign fibrous tissue growths that are not true neoplasms.
Malignant Epithelial Neoplasms
- Malignant neoplasms of epithelial cell origin derived from any of the three germ layers are known as "carcinomas."
Glandular Carcinoma
- The type of carcinoma characterized by glandular microscopic structures is known as "adenocarcinoma."
Mixed Tumors
- Tumors arising from more than one tissue component, containing parenchymal cells of more than one germ layer, are referred to as "mixed tumors."
- An example of such a mixed tumor is “teratoma,” which can contain various tissue types.
Mesenchymal Malignancies
- Malignant neoplasms arising from mesenchymal cell origin, including those derived from connective tissue, bone, and fat, are collectively called "sarcomas."
