Tumor nomenclature
Carcinoma implies epithelial origin,whereas sarcoma denotes mesenchymal origin. Both terms imply malignancy. terms for non-neoplastic malformations include hamartoma(disorganized overgrowth of tissues in their native location, eg, Peutz- Jeghes polyps) and choriostoma9 normal tissue in foreign location, eg, gastric tissue located in distal ileum in Meckel Diverticulum).
- Benign tumor may show well demarcation, well diffreentiation, low mitotic activity, no necrosis, no metastasis.
- Malignant tumor shows poor demarcation, poor mitotic activity, erratic growth, local invasion, metastasis, reduced apoptosis. Upregulation of telomerase prevents chromosome shortening and cell death.
