Sturge-Weber Syndrome (SWS) is a rare, sporadic neurocutaneous disorder. It is typically characterized by unilateral, posterior leptomeningeal angiomas that calcify, glaucoma, and facial portwine tains. Klippel-Trenaunay syndrome (KTS) is a rare congenital syndrome characterized by ipsilateral cutaneous capillary malformations, venous varicosities, and bony or soft tissue overgrowth of the affe...

Tuberous sclerosis complex (TSC), a neurocutaneous syndrome, is characterized by the development of benign tumours affecting different body systems. We herein present a report of a 40-year-old female patient presenting with dental enamel pits and localized gingival overgrowth that eventually lead to the diagnosis of a case of familial TSC. Diagnosis of familial TSC by comprehensive oral examina...

Salmon patches are present in approximately 44% of all neonates. The lesions tend to fade with time and those on the glabellum, eyelids, nose, and upper lip are rarely detected after the age of 6. We report a 33-year-old Chinese female with a salmon patch on the forehead and glabellum. To our knowledge, the occurrence of a salmon patch on the forehead and glabellum in adulthood has not been rep...

A 19-year-old man with refractory generalized epilepsy related to tuberous sclerosis complex (TSC) (figure 1) complained of chronic left facial swelling. Physical examination disclosed typical mucocutaneous findings of TSC (hypomelanotic macules, shagreen patch, ungual fibromas, facial angiofibromas) and a hardened well-limited mass in his left maxilla, evidenced as an odontogenic extensive lef...

Sjögren-Larsson syndrome (SLS) is a rare autosomal recessive neurocutaneous disorder caused by deficiency of the microsomal enzyme fatty aldehyde dehydrogenase. Patients present the classical triad of congenital ichthyosis, mental retardation and spastic di- or tetraplegia. Magnetic resonance imaging (MRI) of the brain usually shows hypomyelination involving the periventricular white matter. Ce...

The intention of this review on nevus comedonicus (NC) is to update on clinical features, pathogenesis, and therapy. NC is a rare epidermal nevus type. It is part of the nevus comedonicus syndrome, a neurocutaneous disorder with ocular, skeletal, and central nervous symptoms. Recently, acne-related signaling pathways and somatic mutations of tyrosine kinase receptors have been identified and ma...

Fanling Integrated Treatment Centre, 6/F, Fanling Health Centre, 2 Pik Fung Road, Fanling, New Territories Tuberous sclerosis complex (TSC), a rare autosomal dominant neurocutaneous syndrome, may be caused by mutations of either the TSC1 or TSC2 gene encoding hamartin and tuberin respectively. It is characterised by cutaneous changes, neurologic conditions and the formation of hamartomas in mul...

Encephalocraniocutaneous lipomatosis (ECCL) is a rare neurocutaneous syndrome characterized by unilateral scalp, facial, and ocular lesions and ipsilateral cerebral malformations. To define the neuroimaging features of this disorder we studied two patients affected by ECCL and compared our data with those reported in the literature. Sonographic, CT, and MR imaging examinations showed quite spec...

Haploinsufficiency of RASA1, located on chromosome 5q14.3, has been identified as the etiology underlying the disorder capillary malformation-arteriovenous malformation (CM-AVM). Recently, haploinsufficiency of MEF2C, located 1.33 Mb distal to RASA1 on chromosome 5q14.3, has been implicated as the genetic etiology underlying a complex array of deficits including mental retardation, hypotonia, a...

One of the few conditions associated with skin ulceration in the neonatal period is aplasia cutis congenita (ACC). ACC or congenital absence of the skin is considered an uncommon anomaly. This malformation commonly appears on the scalp as a solitary lesion, though it can be seen in other surfaces of the body such as the trunk, limbs and face. ACC can be associated with other physical anomalies ...
