HistoryThis section has been translated automatically.

Wise, 1927

DefinitionThis section has been translated automatically.

Rare ectodermal abnormality with circumscribed, congenital, permanent growth disorder of the hair shaft. Formation of an area of frizzy hair, possibly multilocular occurrence. Remarkably, the malformation postnatally shows up as a less hairy area at first, so that initially, an aplasia cutis congenita is more likely.

ManifestationThis section has been translated automatically.

In the first 18 months of life.

LocalizationThis section has been translated automatically.

Capillitium.

Clinical featuresThis section has been translated automatically.

Thin, light, finely curled, non-combed hair in areas of varying size and configuration. These areas stand out clearly from the healthy environment (colour [light hair colour], structure, consistency). The hair has axial twists of 180 degrees and is structurally similar to sheep's wool. The hairs are elliptical or oval and have a reduced diameter. In 50% of cases there are associations with linear epidermal nevi. Other associated malformations (eye malformations, disorders in speech development, tooth anomalies, delayed bone growth) are known (Behle V et al. 2014).

Differential diagnosisThis section has been translated automatically.

Naevoid bundle hair; Pili torti; Pili canaliculi.

Acquired curly hair (see curly hair, acquired)

TherapyThis section has been translated automatically.

Clarification and if necessary treatment of accompanying anomalies. For cosmetic reasons, repeated curling by the hairdresser or perming of the entire hair may be necessary. Excision of individual foci can be discussed if necessary.
