Study Notes
Malignant Tumors (Cancer)
- Malignant epithelial tumors are called carcinomas.
- Carcinomas initially spread via lymph nodes then hematogenous (blood) spread.
- Examples include squamous cell carcinoma & papillary carcinoma.
- Adenocarcinomas develop from glandular epithelium (e.g., lung, stomach)
- Clear cell carcinoma of the kidney is an exception, preferring hematogenous spread.
Malignant Mesenchymal Tumors (Sarcomas)
- Sarcomas spread quickly via hematogenous (blood) pathways.
- Examples include osteosarcoma (bone), liposarcoma (fat tissue), rhabdomyosarcoma (skeletal muscle), fibrosarcoma (connective tissue), and leiomyosarcoma (smooth muscle).
Malignant Neuroectodermal Tumors
- Melanoma originates from melanocytes in the skin.
- Astrocytomas develop from astrocytes in brain/spinal cord.
- Glioblastomas arise from glial cells in brain/spinal cord.
Malignant Neuroendocrine Tumors
- These tumors secrete polypeptide hormones or active amines.
- An example is small cell lung carcinoma which can secrete ectopic ACTH and ADH.
Malignant Hematopoietic Cell Tumors
- Lymphomas originate from lymphocytes in lymphoid tissue.
- Leukemias originate from bone marrow cells.
- Multiple myeloma arises from plasma cells in bone marrow, creating empty spaces in the skeleton.
