Oral fibroma, typically referred to as simply fibroma, is a very common benign lesion in oral pathology.
It is also known as focal fibrous hyperplasia, peripheral fibroma, peripheral ossifying fibroma, fibroid epulis (old term), and fibroepithelial polyp.[1][2][3]
General
- Most common oral cavity tumour.[3]
- Female predominance (female:male = 2:1), usually 30-50 years old.[3]
- Multiple oral fibromas may be seen in Cowden disease.[4][5]
- Histologically similar to fibrous papule.[6]
Microscopic
Features:[6]
- Fibrous stroma - key feature.
- "Very pink" at low power.
- +/-Collagen bundles, may be prominent.
- Prominent (dilated) vessels.
- Overlying (squamous) mucosa benign (flat).
- +/-Hyperkeratosis +/-focal ulceration.[3]
