Crosti-Gianotti Syndrome

Crosti-Gianotti-Adamson-Thoma syndrome is a rare genetic disorder characterized by multiple nevi, purple or violet discoloration of these nevi, abnormal lichenification of the skin and fibrosis of the ligamentous apparatus, as well as dilation of the lungs (this syndrome is called fibroderma en plaquemoisse)

Phacomatous ceroid and psoriasis psoriasis are diseases that are characterized by colored patches and/or multiple keratinized plaques scattered over the skin, often accompanied by itching. Colored spots can appear all over the body due to rare mutations in genes involved in skin pigmentation. In contrast, the presence of psoriatic plaques usually indicates certain defects in hormonal receptors, resulting in a comically psoriasis-like keratinized rash on the skin. Both diseases are not inherited
