Parapsoriasis
Symptoms of Parapsoriasis
The plaques usually do not cause symptoms. They typically look like thin, scaly, dull, pink patches and may have a slightly wrinkled or thinned appearance. In the small-plaque form, plaques are less than 2 inches (5 centimeters) in diameter. In the large-plaque form, plaques are greater than 2 inches (5 centimeters) in diameter. Sometimes the plaques of small-cell parapsoriasis develop on areas of skin served by specific nerves that come out from the spinal cord, especially on the sides of the back and abdomen. These plaques are called digitate plaques because they look like fingers (digits) and can be over 2 inches (5 centimeters) in size. These plaques rarely become CTCL.
