Mould penning flintstone mims syndrome Q87.14

Neuroectodermal symptom complex with nevus sebaceus, malformations and dysplasias of the eyes, skin, brain, skeleton and heart. The syndrome is often combined with hypophosphatemia.

An early embryonic somatic mutation in the HRAS and KRAS genes (see also RAS) can be detected

• The skin changes are present at birth and are the most striking and primary feature of this syndrome. Mostly multiple, predominantly linear naevi sebacei on the whole integument with preference of head and neck, also the oral mucosa may be affected.
• In the course of life multiple melanocytic nevi occur. Eye changes ( dermoid cyst, coloboma, corneal clouding, symblepharon) and cerebral symptoms (cranial asymmetry, cerebral seizures, often mental retardation) may be present. Further malformations are described. Different degrees of severity of all symptoms. Cases with hypophosphatemia of unexplained aetiology are known from the literature. In these cases, fractures, bone deformities, muscle weakness and pain occurred repeatedly.

• Excision of the naevi sebacei, as there is a risk of developing cutaneous tumours such as basal cell carcinomas, spinocellular carcinomas. Cooperation with ophthalmologists and neurologists, among others.
• In hypophosphatemia, substitution with phosphates and vitamin D.
