- Neurofibroma
Haemangioma
These may be superficial and bright red in colour (strawberry naevus) or deep bluish or violet in colour.
- Capillary haemangioma
- Naevus flammeus (port wine stain)
- Cavernous haemangiomas
Capillary haemangioma
It may occur pari passu or more commonly as a part of Sturge-Weber syndrome.
- Capillary haemangioma
- Naevus flammeus (port wine stain)
- Cavernous haemangiomas
Naevus flammeus (port wine stain)
It consists of dilated vascular channels and does not grow or regress like the capillary haemangioma.
