|Lymphomatoid papulosis lesions with ulceration and crusting|
Parapsoriasis refers to one of a group of skin disorders that are characterized primarily by their resemblance to psoriasis (red, scaly lesions), rather than by their underlying cause.
The word "parapsoriasis" was formed in 1902.
The parapsoriasis groups, described and debated for nearly a century, has spawned a confusing nomenclature. There are some authors who prefer to limit the term "parapsoriasis" to large- and small-plaque variants only. However, the following classification scheme is now generally accepted:: 450
- Large-plaque parapsoriasis
- Small-plaque parapsoriasis
- Pityriasis lichenoides
- Lymphomatoid papulosis
