ManifestationThis section has been translated automatically.
- Adult or solar form: more common form, especially in chronic light exposure or after contact with photosensitisers. Occurs in adulthood.
- Juvenile form (rare): occurring before puberty. Autosomal dominant mode of inheritance.

Clinical featuresThis section has been translated automatically.
HistologyThis section has been translated automatically.
Homogeneous, circumscribed, amophilic or basophilic, PAS-positive colloidal conglomerates in the upper dermis. The deposits are cell-poor. Typical are the preparation-related cracks and fissures within the colloid nodule. The overlying epithelium is flattened and atrophic. In the adult form, solar elastosis is obligatory, which is missing in the juvenile form. Versch. Investigators could stain the (keratin-)colloid with keratin-AK in the juvenile form (compare keratin-amlyoid in LIchen amyloidosus)
