Acquired ichthyosis
Overview
Ichthyosis is scaling and flaking of skin ranging from mild but annoying dryness (xeroderma) to severe disfiguring disease (inherited ichthyosis). Ichthyosis can also be a sign of systemic disease.
Acquired ichthyosis is relatively rare, but may be caused by any of the following:
Leprosy (extremely rare in the US)
Underactive thyroid
Lymphoma ( Hodgkin's, Non-Hodgkin's)
Sarcoidosis
AIDS ...
Acquired ichthyosis: Ichthyosis may be an early manifestation of some systemic diseases (eg, leprosy, hypothyroidism, lymphoma, AIDS). Some drugs cause ichthyosis (eg, nicotinic acid, triparanol, butyrophenones).
Both hereditary and acquired Ichthyosis vulgaris can be soothed in the short term by moisturizing the skin. Any cracks in the skin should be treated immediately to prevent an infection.
Ichthyosis not caused by genetics, referred to as acquired ichthyosis, is very rare. This type usually manifests in adulthood and is usually associated with other internal diseases, such as cancer, thyroid disease or chronic renal failure.
Viral skin infections, urticaria, skin flakiness and acquired ichthyosis, disorders of sweat and sebum, sweating.
