Parapsoriasis
Introduction
Parapsoriasis refers to a group of skin diseases characterized by small and red or scaly patches on the skin. Parapsoriasis is not a type of Psoriasis . It is so-named because it causes scaly patches (plaques) to form on the skin that appear similar to those caused by psoriasis. The difference between the two disorders is that in parapsoriasis, the plaques are thinner than they are in the most typical form of psoriasis. There are two forms of parapsoriasis: Small-plaque form Large-plaque form Small-plaque parapsoriasis is usually noncancerous (benign). However, extremely rarely, small-plaque parapsoriasis turns into Cutaneous T-cell Lymphomas (CTCL), which is a type of skin cancer that is caused by specific types of white blood cells called Among people with large-plaque parapsoriasis, 10% develop CTCL every 10 years.
