Study Notes
Tumor Classification
- Tumors are classified based on clinical course and tissue of origin.
- Types of tumors include:
- Mesenchymal tumors
- Epithelial tumors
- Mixed tumors
- Teratomas
- Other miscellaneous tumors
Tumor Behavior
- Tumors are characterized as either benign or malignant.
- Benign tumors are considered "harmless."
- Malignant tumors are associated with cancer and labeled "harmful."
Nomenclature of Benign Tumors
- Benign tumors typically have names ending with the suffix “OMA.”
- Naming conventions include:
- Prefix (type of cell) + suffix (oma)
- Name of the origin cell + morphologic character + suffix (oma)
Examples of Benign Tumors
- Ovarian cyst adenoma: a benign tumor of the ovary.
- Epithelioma: tumors of squamous epithelial cells.
- Adenomas arise from glandular tissues (colon/endocrine glands).
Mesenchymal Tumors
- Common benign mesenchymal tumors include:
- Fibroma: tumor of fibroblasts.
- Chondroma: tumor of cartilage.
- Osteoma: tumor of osteoblasts.
- Leiomyoma: tumor of smooth muscle.
- Rhabdomyoma: tumor of skeletal muscle.
Benign Epithelial Tumors
- Benign tumors of epithelial origin show greater complexity based on histogenesis and architecture. Key types include:
- Adenoma: benign tumors of glandular origin (e.g., thyroid adenoma, colonic adenoma).
- Cystadenomas: adenomas that produce large cystic masses, commonly found in the ovaries.
- Papillomas: tumors with finger-like projections that extend beyond the epithelial surface.
- Polyp: tumors that create finger-like projections extending into the lumen of hollow organs, such as colon polyps.
