Ichthyosis Information and Treatment
Ichthyosis is a family of dermatological
conditions. People with ichthyosis have scaly skin which can vaguely
resemble the scales of a fish. Acquired ichthyosis is not inherited
and occurs for the first time in adulthood. It is usually associated
with some general systemic disease, such as underactive thyroid
states, sarcoidosis, lymphoma, generalised cancer or HIV infection.
It may be provoked by certain medications (such as nicotinic acid
and hydroxyurea). Ichthyosis vulgaris, accounts for 95% of all
ichthyosis cases. Inheritance is autosomal dominant i.e. it is
passed from a parent to about half their children. Signs and
symptoms of ichthyosis vulgaris usually become apparent within the
first year of life. Some of these conditions primarily affect the
skin such as Ichthyosis Vulgaris X-linked Ichthyosis; Non-Bullous
Ichthyosiform Erythroderma; Lamellar Ichthyosis.
Harlequin Ichthyosis is a chronic skin disorder.
Harlequin Ichthyosis is a common condition which can occur in any
age group. These scales can be present at birth, but usually first
appear in early childhood. Sometimes ichthyosis vulgaris disappears
entirely for most of the adult years, only to return later. Though
most cases are mild, some cases of ichthyosis vulgaris are severe.
Since there is no cure, treatments focus on controlling the signs
and symptoms. Ichthyosis may be annoying but seldom affects medical
health. It usually improves during adulthood but may recur when a
person becomes elderly. The various forms of Ichthyosis are
distinguished from one another by:1) extent of the scaling and how
widely and where the scaling is scattered over the body; 2) the
presence or absence and intensity of reddening of the skin (erythroderma);
3) the mode of inheritance; and 4) the character of associated
abnormalities. Ichthyosis involves development of dry, scaly skin.
It may be associated with atopic dermatitis , keratosis pilaris
(small bumps on the back of the arms), or other skin disorders.
