Milia en plaque Q82.9

Hubler et al. 1978

Rare, acquired, plaque-shaped or linear (described are arrangements in the Blaschko lines) aligned, grouped or disseminated, 0.1-0.4 cm large, non-irritant, follicular papules at different parts of the body (especially in the face). Excluded are blistering underlying diseases or previous traumas (e.g. burns), or a pronounced actinic elastosis, which can lead to primary milia formation.

Localized follicular hamartoma that affects only the excretory duct of the follicle ("miliary nevus").

In individual cases an autosomal dominant inheritance is the basis.

Naevoid milia can also be a partial symptom of a complex genodermatosis.

Infants and adolescents, also younger adults.

In principle ubiquitous on the skin. Such follicular hamartomas are mainly described retroauricularly, on the eyelids and periocular, on the cheeks, palms of the hands and soles of the feet. (see also fig.).

The localized milia acquired at an advanced age are usually found in massively light-damaged skin and are subject to a similar pathogenetic principle of origin as the formation of comedones in M. Favre-Racouchaud.
