Sinking skin syndrome in a decompressive craniectomy series: Clinical and radiological features.

Background: The sinking skin syndrome (SSS) is a particular complication after a decompressive craniectomy (DC). It still remains a poorly understood and underestimated entity.

Methods: Retrospective case series of craniectomized patients with and without SSS.

[Becker's nevus associated with epidermal nevus: another example of twin spotting?].

Linear epidermal nevi are believed to be caused by an autosomal dominant lethal mutation that can only be expressed by mosaicism. Becker's nevus can be explained by paradominant inheritance which is only manifested clinically by an acquired loss of heterozygosity. We present the case of a 16-year-old female with an epidermal nevus located on the left side of the neck, and also a Becker's nevus located on the ipsilateral shoulder.
