Clinical features
This section has been translated automatically.

Always skin involvement: lenticular atrophy and aplasia (see below: Aplasia cutis congenita) of the skin, confluent to larger areas. Dermal hypoplasia with hernia-like bulging of the fatty tissue is always present, but with varying degrees of severity. Overall, the result is a poikiloderma characterized by teleangiectatic, hypo- or hyperpigmented foci and mottled scarring.

Raspberry-like papillomas of the lips, the oral mucosa and the genitoanal mucosa.

Thick scalp hair, foci with scarred alopecia, onychodystrophy, disorders of sweat secretion. Pigment anomalies or pigmentation disorders, rarefied or missing eyebrows, skin tumours and cysts, dysplastic finger and toe nails.

About 10 patients with a unilateral infestation pattern are described.

Extracutaneous manifestations: skeletal involvement (90% of cases): syn- and polydactylia, hypo- and aplasia of fingers and toes, kyphosis, scoliosis, spina bifida, vertebral anomalies, malformations of clavicles and ribs, longitudinal striation of metaphyses of long tubular bones (osteopathia striata), cranial anomalies. Dental anomalies and eye involvement in about 50% of cases: iriscoloboma, microphthalmia, anophthalmia, strabismus, nystagmus, aniridia. Rarely affected other organs: cardiac and renal malformations, auricular malformations, conductive hearing loss, mental retardation.

Hypoplasia of the corium, repair of the elastic and collagen fibres, capillary proliferation. The subcutaneous fatty tissue can reach the basal membrane of the epidermis.
