What is a fibroma? Clinical features?
benign Reactive hyperplasia of fibrous connective tissue.
-Smooth surface, sessile, pink nodule.
What is peripheral ossifying fibroma? Clinical features? Recurrence?
Tumor or reactive lesions exclusively on the gingiva
- Nodular, red to pink, firm.
- Higher recurrence rate than typical benign tumor.
What is a fibrosarcoma?
Malignant fibrous tumor.
What is pyogenic granuloma? categorized as? Clinical features? Also known as?
Tumorlike growth, generally non-neoplastic.
- Categorized as lobular capillary hemangioma
- Rapidly growing, vascular (blanches), well circumscribed.
- AKA pregnancy tumor
What is a peripheral giant cell lesion? Seen? Clinical features?
Vascular, tumor-like growth that is reactive.
- Seen exclusively on gingiva or edentulous alveolar ridge
- Firm, vascular.

What is lymphangioma? Clinical features?
Benign growth of lymphatic vessels.
-Doesn’t blanch, Congenital, Found on dorsum of tongue, has a frog egg appearance.

Malignant vascular tumor.
What is traumatic neuroma? clinical features?
Reactive proliferation of axons after trauma.
-Anesthesia or dysthesia, pain on palpation.
What is a schwannoma? Clinical features?
Benign neoplasm of Schwann cells
-not painful on palpation, non vascular.
What is a neurofibroma?
Benign fibrous neural tissue tumor.
What is neruofibromatosis? Clinical features?
Hereditary syndrome of neural tissue.
-Multiple neurofibromas, Cafe Au Lait, crowe’s sign (axillary freckling), Lisch nodules on eye.
What is Granular Cell tumor?

What is Malignant peripheral nerve sheath tumors?
Malignant neural tumor.
What is a leiomyoma? Clinical features?
Benign tumor of smooth muscle.
-Slow growing, firm, mucosal nodule with pink or bluish hue (if it proliferates the vasculature as well).
What is leiomyosarcoma?
Malignant tumor of smooth muscle.
What is Rhabdomyoma?

What is a lipoma? Clinical features?
Benign tumor of fat tissue
-Yellow or pink hue
What is liposarcoma?
Malignant tumor of fat
What is congenital epulis? Clinical features?
At birth only on alveolar ridge tumor like lesion.
- pink-red, smooth surfaced, single or polypoid mass.
- 90% on females.
