Aplasia cutis congenita

Last Updated: 2019-08-27

Author(s): Anzengruber F., Navarini A.

ICD11: -

Congenital malformation of the skin on the head.

Incidence: 3/100 000.

Diaphragm eye ACC

Non-membrane ACC

Mostly spontaneous, rarely AD or AR.

There are several associated syndromes such as: Adam's Oliver syndrome, pyloric stenosis, Partau syndrome, etc.

Membrane ACC: Mostly circular hair/epidermis-less, rarely bullous, spot on the capillitium.

Non-membranous ACC: Larger and irregular hairless areas on the capillitium, which can extend to the nodes or meninges.


No biopsy, especially with non-membrane ACC!

In non-membrane ACC, an MRI is necessary to detect the depth of the pathology. Only then should a cosmetic surgical procedure be planned, if necessary.
