Zur Frage der Faltenbildung der Kopfhaut, inbesondere der Cutis verticis gyrata

Is cutis verticis Gyrata-Intellectual Disability syndrome an underdiagnosed condition? A case report and review of 62 cases

Cutis Verticis Gyrata-Intellectual Disability (CVG-ID) syndrome is a rare neurocutaneous syndrome characterized by intellectual disability and scalp folds and furrows that are typically absent at birth and are first noticed after puberty. First reported in 1893, the syndrome was mainly identified in subjects living in psychiatric institutions, where it was found to have a prevalence of up to 11.4%. Most patients were reported in the literature during the first half of the 20th century. CVG-ID is now a less reported and possibly under-recognized syndrome. Here, we report a patient with CVG-ID that was diagnosed using the novel approach of magnetic resonance imaging and we conduct a systematic review of all patients reported in the last 60 years, discussing the core clinical features of this syndrome. © 2016 Wiley Periodicals, Inc.

Oxycéphalie chez trois paires de jumeaux univitellins, associée dans un des cas à une cutis frontis gyrata

Description of 3 cases of identical twins affected by concordant oxycephaly. In the first case, one of the twins had a son who was likewise afflicted by a typical scaphocephaly. In the second case, both children showed also a convergent concomitant strabismus, which was latent in one and manifest in the other, and moreover a concordant ptosis. In the third case, the oxycephaly was associated with cutis frontis gyrata homologous in both twins.

A confrontation of the cases of oxycephaly in identical twins based on the literature and our personal cases, shows clearly a majority in favour of concordance : 25 concordant pairs as compared to 10 discordant ones; the fraternal twins (7-8 cases) are all discordant as regards oxycephaly. The cases of discordant oxycephaly in monozygotic twins must therefore be interpreted as the result of an unstable gene of feeble penetrance. The conclusion of the genotypic origin of oxycephaly is corroborated by some pedigrees showing a transmission through 2 or more generations. Two reported cases with consanguinity of the parents suggest likewise the possibility of recessive inheritance.

The association of oxycephaly with cutis frontis gyrata, as observed in our third case, having not yet been described, we cannot for the moment decide whether this combination is due to chance or whether there exists a pathogenic correlation between both anomalies.

Cutis verticis gyrata secondary to acne scleroticans capitis

We report the case of a 35-year-old patient with secondary cutis verticis gyrata (CVG) that histologically presented as acne scleroticans capitis. Clinically, the diagnosis of acne conglobata was made. The CVG developed under systemic corticosteroid treatment of an ulcerative colitis. Corticosteroids were discontinued and a therapeutic attempt was made with isotretinoin. Although under this treatment the conglobate acne healed, the CVG remained unaltered. Dermatosurgical intervention by a scalp reduction plasty finally resulted in a marked improvement of symptoms and acceptable cosmetic outcome.
