Dominant Ichthyosis vulgaris Symptoms and Signs
Symptoms of inherited Ichthyosis vulgaris often manifest themselves when children reach four years of age. These symptoms improve as the child becomes older. These symptoms may grow even more severe during old age. The acquired Ichthyosis vulgaris condition, in the other hand, usually manifest during adulthood. Severe cases, which is very rare, also exist. These cases would entail skin scaling everywhere in the bdoy. Areas, however, that have greatest concentration of the sweat glands are not always affected whereas areas where the skin often rubs against other skin, such as the groins, arm pits. The "folded" areas of the knees area and elbow are also less affected. When the scales build up is really bad, the person suffering a very severe case would often suffer "prickly itch". At this rate, he or she really needs to sweat. This becomes difficult, however, because of the build up of scales.
Dominant Ichthyosis vulgaris Treatment
Various topical treatments are available to "exfoliate" the scales. These include various lotions that contain alpha-hydroxy acids.
