What is ichthyosis vulgaris?

Many people with ichthyosis vulgaris do not even realize they have it. The manifestations are so mild that they are often mistaken for dry skin and are kept under control through the use of moisturizing creams.
What are your causes?
Most commonly, ichthyosis vulgaris arises from inheriting a genetic mutation of one or both parents. If it is present in only one of the parents, the course of the disease will be milder. If both parents have the mutation, the disorder tends to be more serious.
It is almost always present at birth or appears in the first years of life. It usually goes away during early childhood, and symptoms no longer occur. However, there is also a small group of sufferers who re-experience the manifestations in adulthood.
Cases of ichthyosis vulgaris acquired in adulthood are rare. At this stage of life it is usually the result of the ingestion of some medications. Other times it is associated with diseases such as cancer, thyroid disease, or kidney failure.
Likewise, there are cases of ichthyosis vulgaris that are related to other skin diseases such as atopic dermatitis or keratosis pilaris. In the latter case there may be white or red bumps on the skin that are similar to acne.

- Dry Skin.
- Presence of small tile-shaped scales. The color can be white, gray or brown.
- Scaly scalp.
