Goltz, syndrome
|
(Focal dermal hypoplasia, Goltz-Gorlin syndrome)
Not to be confused with Gorlin or Gorlin-Goltz syndrome
Rare: frequency estimated to be 2/100,000 newborns. Sporadic or autosomal dominant transmission linked to a mutation in the PORCN gene on Xp-11.23 (80% of patients are female).
Clinical manifestations:
- skin abnormalities: skin appendages, stripped hypoplasia of the dermis; with atrophy and pigmentation (telangiectasia) of the overlying skin and hernia of the subcutaneous fat (yellowish or reddish nodules that follow the lines of Blascko); palmar hyperkeratosis, nail dystrophy
- skeletal abnormalities are present in 60 % of cases: syndactyly, kyphoscoliosis, spina bifida occulta, aplasia or hypoplasia of a clavicle, short stature; longitudinal striation of the long bones (osteopathia striata)
- ocular anomalies: coloboma (30 % of cases), microphthalmia, strabismus
- high arched palate
- microdontia, hypoplasia of the dental enamel, gastro-esophageal reflux
There is a risk of cellular hypertrophy at the level of the mucocutaneous periorificial junctions: gums, eyes, mucosae, anal and vaginal mucosae with an accumulation of fatty tissue that takes the appearance of papillomas. Frequent mental retardation.
Anesthetic implications:
check the presence of oropharyngeal and laryngeal papillomatosis: if there are such lesions, major risk of difficult intubation; difficult peripheral venous access; risk of hypothermia; fragile skin.
