[Cutaneous manifestations of malabsorption diseases (author's transl)].

The document discussed the relationship between malabsorption (M) and skin diseases, focusing on how M can cause skin manifestations or be caused by skin diseases. It highlighted that skin complications occur in 10% to 20% of M cases, often due to vitamin or amino acid deficiencies, and improve with M treatment. Common skin issues included pigmentation changes, ichthyosis, keratosis, nail brittleness, and hair loss. The report also covered dermatogenic enteropathy, where M results from extensive skin disease, such as psoriasis or eczema, with symptoms improving only when the skin condition is treated. The document reviewed these associations and their clinical implications.
