Soft Tissue Tumors II (Benign) 702 | Qiestions An
Answers 2024| Must Read
1. "new growth"
- abnormal and uncontrolled proliferation
- not controlled by regulatory functions; does NOT regress after removal of stimulus: Review:
What does neoplasm mean?
2. - involves normal cells
- often response to tissue damage
- proliferation DOES stop when stimulus is removed: How is hyperplasia differ- ent than
neoplasm?
3. malignant
benign: tumors are typically firm/fixed while tumors are
often movable on palpation.
4. Benign:
- small; slow-growing
- encapsulated (non-invasive)
- well differentiated
- no metastasis
- movable
Malignant:
- large; fast-growing
- not encapsulated (invasive)
- poorly-differentiated
- possible metastasis
- mitotic figures
- firm/fixed: What are characteristics of benign vs malignant tumors?
5. -oma
(ex. lipoma, fibroma, chondroma): Benign tumors typically end in the suffix
; however, epithelial tumors have a more complex nomenclature.
6. sarcoma
carcinoma: and are malignant tumors.
7. Keratoacanthoma
--> enlargement is rapid: 1-2 cm within 4-6 weeks, followed by spontaneous resolution: is a self-
limiting epithelial proliferation with clinical/histo- logical similarities to squamous cell carcinoma.
