Parapsoriasis: Causes, Treatment, and More

Signs and Symptoms of Small-Plaque Parapsoriasis

Small-plaque parapsoriasis typically cause skin lesions with the following characteristics:

– Less than 5 centimeters or 2 inches in diameter

– Oval or round in shape

– Yellow-brown to pink in color

– Flat or raised

These lesions can be found on the legs, flanks, trunks, and surrounding areas. While small-plaque parapsoriasis is chronic, it tends to be benign and does not develop into cancer. This type also has a sub-type called digitate dermatosis, which cause thin and long lesions on the body’s sides.  [3]

Signs and Symptoms of Large-Plaque Parapsoriasis  

Skin lesions caused by large-plaque parapsoriasis may have the following features:

– Typically larger than 5 centimeters in size

– Either brown or brown-red in color

– Irregular shapes

They can be found on parts of the body that are not exposed to sunlight, such as the thighs, under the breasts, under the buttocks, as well as the buttocks. Large-plaque parapsoriasis would develop into cancer in approximately 30 percent of reported cases. [4]
