**Core Concept**
Sturge Weber syndrome is a rare neurocutaneous disorder characterized by the presence of a port-wine stain on the face, typically in the distribution of the trigeminal nerve, along with leptomeningeal angiomatosis and glaucoma. It is associated with abnormalities in the development of the neural crest cells.

**Why the Correct Answer is Right**
Sturge Weber syndrome is characterized by the presence of a port-wine stain, leptomeningeal angiomatosis, and glaucoma. The port-wine stain is a vascular malformation that results from the abnormal development of the neural crest cells. Leptomeningeal angiomatosis is a feature of the syndrome, which involves the abnormal proliferation of blood vessels in the meninges. Glaucoma is also a common feature of the syndrome, resulting from the abnormal development of the choroid and ciliary body. The correct answer should not be a feature of the syndrome.

**Why Each Wrong Option is Incorrect**
**Option A:** Leptomeningeal angiomatosis is a feature of Sturge Weber syndrome, so this option is incorrect.

**Option B:** Glaucoma is a common feature of Sturge Weber syndrome, so this option is incorrect.

**Option C:** Port-wine stain is a characteristic feature of Sturge Weber syndrome, so this option is incorrect.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that Sturge Weber syndrome is a rare neurocutaneous disorder that affects the development of neural crest cells, leading to characteristic features such as port-wine stains, leptomeningeal angiomatosis, and glaucoma.

**Correct Answer:** D
