Colloidmilium juvenilesL72.8

Woolridge and Frerichs 1960

Very rare, probably autosomal recessive inherited disease, which can be pathogenetically distinguished from the adult form of colloidal milium. In this case, there is a focal deposition of colloid as a degradation product of keratinocytes (in contrast to the adult form of colloid milium).

Very rare, < 50 cases known in world literature; m:f=1:1;

Unknown; familial occurrence is described several times. In contrast to the adult form, the juvenile colloidalmilium is a deposited "keratin colloid" in which gap junctions and desmosomes have been detected by electron microscopy.

Manifestation prepubertal; beginning of the first changes in the 6th-7th LJ

Light-exposed areas of the face (cheeks, perioral, periocular)

Gradual development of UV-triggered, symptom-free, soft, translucent, yellowish papules and plaques. On pressure, gelatinous material can be expressed from the lesions after incision.
