Xerosis is a common condition worldwide and it is a prominent feature of both syndromic and non-syndromic ichthyoses.
Both xerosis and ichthyosis can have a considerable negative impact on the quality of life of patients.
The diagnosis of xerosis and inherited ichthyoses is based on history, clinical manifestations, associated abnormalities, and family history, but several specific investigations may aid in the diagnosis of syndromic ichthyoses.
Managing xerosis includes applying topical moisturizers with key components like lipids and humectants while proactive preventive measures are vital for preventing triggers of the condition.
Understanding and addressing triggers such as temperature, low humidity, sunlight exposure, and environmental conditions like air conditioning or heating can be essential in managing xerosis effectively.
Evaluating the overall severity of xerosis and ichthyosis may include the use of established tools like the Dermatology Life Quality Index (DLQI) and the newer Ichthyosis Scoring System (ISS) to assess their impact on patients’ quality of life.
Identifying signs such as brittle hair, neurological abnormalities, and palmoplantar keratoderma can be suggestive of syndromic ichthyoses. These indicators are valuable for recognizing these rare conditions and guiding further examination or evaluation.
