hi and pleased to answer you
The ripples noticed are ridges of skull surface. This
deformity is found in a disease called Cutis verticis gyrata.
Cutis verticis gyrata (CVG), of the
scalp, is a rare and progressive skin disease of the scalp. It is characterized by hypertrophy and cutaneous hyperlaxity forming folds similar to the gyri of the
cerebral cortex. The patient may present a deformation of the scalp with numerous longitudinal and transverse folds with social and aesthetic discomfort. A surgical resection of the cutaneous excess in a transverse and longitudinal plane is carried out. The treatment of this disease is surgical, by the excision of the skin folds and re-tensioning of the scalp. The number and location of the
incisions must preserve the vascularization of the scalp and take into account the evolutionary character of this pathology.
Cutis verticis gyrata (CVG), or vorticelated pachyderma of the scalp, is a rare and progressive condition of the scalp and / or facial skin. It is characterized by hypertrophy and cutaneous hyperlaxity forming folds similar to the surface of the cerebral cortex. These folds can be the cause of an aesthetic, social and functional discomfort (maceration, infection). This disease was reported for the first time by Alibert in 1837 under the term of "cutis sulcata".
