Malignant tumor originating from connective tissue (mesenchymal cells).
Carcinoma
Carcinoma
Malignant tumor originating from epithelial cells.
Study Notes
- Sarcoma and carcinoma are terms used to classify cancers based on their tissue of origin
Sarcoma
- Sarcomas are malignancies that arise from connective tissues (mesenchymal)
- Connective tissues include:
- Bone
- Cartilage
- Fat
- Muscle
- Blood vessels
- There are two main types of sarcoma:
- Soft tissue sarcoma
- Bone sarcoma (osteosarcoma)
Carcinoma
- Carcinomas are malignancies that arise from epithelial cells
- Epithelial cells line surfaces of the body
- Inside and outside
- Carcinomas are the most common type of cancer
- Subtypes of carcinomas
- Adenocarcinoma: develops in the epithelial cells that produce fluid or mucus
- Squamous cell carcinoma: develops in the epithelial cells just beneath the outer surface of the skin
- Basal cell carcinoma: develops in the basal cells, which are small, round cells found in the base of the epidermis
- Transitional cell carcinoma: develops in the transitional epithelium or urothelium
