Harlequin-Type Ichthyosis is a medical condition where the skin of an infant becomes thick and scaly.

The change occurs in the keratin layer of the skin. Large and thick, diamond shaped scales, red in color, can be seen.

The scaly nature of the skin causes the infant to have difficulty with movement and respiration.

It is a very rare condition.
