Exam 3 Soft Tissue Tumors (No effect) Flashcards
Where does carcinoma and sarcoma originate from and indicates
A malignant tumor of epithelial origin and sarcoma which indicates a malignant tumor of Connective tissue origin.
What are the difference between carcinoma and sarcoma?
- Carcinomas are 10 times more common than sarcomas
Where does carcinoma metastaize?
Lymphatic system
Where does sarcomas metastasize?
Circulatory system
Tumors of soft tissue include?
- benign and malignant tumors of adipose (fat) tissue, nerve, muscle, blood, and lymphatic
vessels. - But it is not completely independent from
bone
Benign Tumors of Fibrous CT are?
- Reactive hyperplasias the most common
- Result from overzealous repair
- Composed of collagen, endothelial cells,cementum and/or bone, or giant cells
- If on the gingiva and you don’t know its exact histological nature, it’s called an EPULIS
- Common lesions include the Fibroma, Ossifying fibroma, Pyogenic granuloma, and Giant cell granulomas
What is a Fibroma ?
- Also called irritation or traumatic fibroma
- Occurs in response to chronic trauma like cheek biting
What is fibroma composed of ?
dense scar-like CT with lots of collagen fibers and few blood vessels.
How does Fibroma appear?
appears as a domelike growth with smooth surface and normal color
What is the treatment of fibroma?
Excision- but will not resolve spontaneously due to excess collagen
What is Epulis Fissuratum?
A type of Irritation fibroma
What is epulis fissuratum caused by?
Ill fitting dentures
What is a frenal tag?
- Hyperplastic fibrous tissue
- Small finger like projection
What is the frenal tag treatment?
Does not require treatment
What is ossifying fibroma?
A reactive hyperplasia found on the gingiva
Where does ossifying fibroma origininates from?
From the PDL where
Fibroma
Epulis Fissuratum
Ossifying Fibroma
What is pygogenic granuloma?
- Fast Growing
- Occurs as exuberant granulation to irritation
- Appears Fiery red, bleeds easily
- Pregnancy Tumors- second and third trimesters
pygogenic granuloma/ pregnancy tumor
Giant Cell Granuloma is ?
- Ulcerated, bleeding
- Occus on the gingiva
- Reactive hyperplasia
- Develops in response to an irritant
- Younger patient, most common in females
- Chronic inflammatory cells seen, multinucleated giant cells- along with well vascularozed CT
Giant Cell Granuloma
What type of Giant Cell Granuloma occurs in the gingiva?
Peripheral Giant Cell Granuloma
What type of giant cell granuloma occurs with the bone?
Central Giant Cell Granuloma
