Sturge-Weber syndrome (SWS) is a rare congenital developmental disorder characterized by unilateral cutaneous vascular malformation (nevus flammeus or port-wine stains) in association with ipsilateral leptomeningeal angiomatosis and glaucoma. This article presents a case of SWS associated with gingival hyperplasia and pyogenic granuloma.
Keywords: Congenital developmental disorder, neurocutaneous ocular disorder, pyogenic granuloma

| Introduction|| |
It was first described by Schimer in 1860, and Sturge in 1879 described more specific features of SWS.  SWS is a developmental defect that occurs in first month of gestation period. In this condition, vascular plexuses persist around the cephalic portion of neural tube. Normally, theses plexuses develop in the sixth week of intrauterine life and undergo regression during the ninth week.  These persistent vascular plexuses and form venous angioma affect leptomeninges, face, jaws, and soft tissues. 
| Case Report|| |
A 17-year-old female patient reported to the Department of Periodontology with chief complaint of bleeding gums and reddish discoloration (port-wine stain) on the right side of the face [Figure 1]. This discoloration was present since birth and taking dark color with age. Past medical history revealed that she was suffering from convulsive disorder since the age of 3 years.
Extraoral examination revealed that port-wine stain had unilateral distribution involving the right side of the face and extended up to the middle of forehead, eye, half of the nose, and right side of the upper lip. Eye examination showed dilated blood vessels on the right side of eye and left eye appeared normal [Figure 2].
Intraoral examination showed gingival hyperplasia and soft tissue overgrowth on the right side [Figure 3], and theses hyperplastic tissues showed blanching on application of pressure.

In treatment, oral prophylaxis was done and instruction for oral hygiene maintenance was given, and the patient was advised to use chlorhexidine mouthwash. The soft tissue overgrowth was surgically removed by neodymium-doped yttrium aluminum garnet (NdYag) laser and was sent for histopathological examination, which showed pyogenic granuloma [Figure 4]. NdYag laser was used for the purpose of achieving immediate hemostasis, minimal damage of surrounding tissues, and less postoperative pain.

On radiographic examination, a lateral cephalogram showed tram-line calcification [Figure 5]. Computed tomography (CT) of alveolar bone showed severe bone loss on the affected side of the oral cavity [Figure 6]. Blood investigations were normal. Based on the history and clinical and radiological findings, a diagnosis of SWS was made.

| Discussion|| |
It is an uncommon, nonfamilial, typical neurocutaneous ocular disorder. The etiology of this condition is remains unclear. According to some authors, the persistent vascular plexus and form venous angioma affect leptomeninges, face, jaws, and soft tissues.
Angioma of leptomeninges alternate the vascular flow causing seizers, mental retardation, and hemiplegia.  Facial angioma develops characteristic stains that usually occurs in area supplied by ophthalmic and maxillary division of trigeminal nerve. 
According to Bioxeda et al., the distribution of port-wine stains mainly unilateral follows the V2 branch of the trigeminal nerve. They observed that out of the total 121 patients, in 88% the distribution of port-wine stains mainly unilateral follows the area of V2 branch. 
SWS is referred to as "complete" when it affects both central nervous system (CNS) and facial angioma, and "incomplete" when only one of these areas is affected.
Roach classified SWS into the following four types on the basis of their clinical manifestation of affected patient  :
Type I-Both facial and leptomeningeal angiomas may have glaucoma.
Type II-Facial angioma and no CNS involvement.
Type III-Isolated leptomeningeal angioma usually no glaucoma.
Type IV-When SWS is associated with other disorders such as tuberculosis and sclerosis.
The clinical manifestation and various investigation differentiate SWS from other disorders such as Rendu-Oslar-Weber syndrome, angio-osteodystrophy, and Von Hippel-Lindau disease. ,
