What distinctive skin condition is associated with Sturge-Weber angiomatosis?

1. Yellowish skin lesions

2. Port wine stain

3. Cherry angiomas

4. Freckles

The correct answer is: Port wine stain

Sturge-Weber angiomatosis is primarily characterized by the presence of a port wine stain, which is a type of vascular malformation. This condition manifests as a flat, pink or red birthmark that typically appears on one side of the face, often over the area of the forehead and upper eyelid. The port wine stain results from an overabundance of blood vessels in the skin and is a direct consequence of the underlying neurological conditions associated with Sturge-Weber syndrome. The presence of a port wine stain in individuals with Sturge-Weber angiomatosis can be indicative of potential complications, particularly neurological issues such as seizures or developmental delays. Understanding the implications of these skin lesions is crucial for healthcare providers, enabling them to monitor and manage their patients effectively, considering the systemic associations that may arise from this particular condition.
