Study Notes
Neoplasia: Key Concepts and Terminology
- Neoplasia refers to new growth of cells, either benign or malignant.
Benign Tumors
- Characteristics: Encapsulated, localized growth, slow growth rate, non-invasive.
- Examples:
- Lipoma (adipose tissue)
- Chondroma (cartilage)
- Hemangioma (blood vessels)
- Lymphangioma (lymphatic vessels)
- Rhabdomyoma (skeletal muscle)
- Papilloma (bladder transitional epithelium)
- Nevus (melanocytes)
- Meningioma (meninges)
- Pleomorphic adenoma (epithelial and mesenchymal components)
Malignant Tumors
- Characteristics: Invasive growth, metastasis (spread to other locations), rapid growth.
- Classification by Origin:
- Epithelial origin (Carcinomas): Squamous cell carcinoma (skin), Transitional cell carcinoma, Adenocarcinoma (glandular tissues).
- Connective tissue origin (Sarcomas): Liposarcoma, Leiomyosarcoma (smooth muscle), Rhabdomyosarcoma, Osteosarcoma (bone), Chondrosarcoma.
- Hematopoietic origin: Lymphomas, leukemias.
- Other: Choriocarcinoma (placenta), Melanoma (melanocytes)
- Germ cell origin: Teratoma (multiple germ cell layers)
Specific Tumor Types
- Carcinomas arise from epithelial tissue, a general category encompassing many different types based on the origin.
- Sarcomas arise from mesenchymal tissues and include tumors such as liposarcoma, leiomyosarcoma, and osteosarcoma.
- Teratoma is a tumor composed of multiple germ cell layers.
- Hamartoma: Tumor containing normal tissue in an abnormal location.
- Choristoma abnormal tissue in an ectopic location.
- Myeloma malignant tumor of plasma cells.
