Oral hemangioma - Oral Mucosal Lesion
The more common vascular malformations in the oral cavity, loosely called hemangiomas, are proliferations of capillaries or venules that do not involute but persist and grow very slowly over years. They tend to occur on the tongue, buccal mucosa, and labial mucosa. The intrabony lesions are best classified as "vascular malformations."

Differential Diagnosis & Pitfalls
- Lobular capillary hemangioma (pyogenic granuloma) is a reactive proliferation of blood vessels that occurs in adults and during pregnancy. It is usually present on the gingiva, buccal mucosa, or labial mucosa.
- Peripheral giant cell granuloma
- Kaposi sarcoma may present as a purplish-blue nodule with a tendency to bleed. It is seen in the oral cavity, primarily in those with AIDS.
- Oral varices
- Some abscesses may appear purplish-red, but these are always associated with an infectious process, odontogenic or otherwise.
- Leukemic infiltration
- Large varices may appear similar but generally occur in older individuals and are common on the lip.
- Sturge-Weber syndrome is a vascular malformation involving the soft tissues of the face and oral mucosa that follows the distribution of the trigeminal nerve. If the ophthalmic division is affected, there is usually concomitant meningeal involvement. Oral lesions are diffuse, purple plaques, and the overlying skin has a port-wine stain.
- Granulomatosis with polyangiitis
- Squamous cell carcinoma
