Parapsoriasis Classification and external resources ICD-10 L41 ICD-9 696.2 eMedicine derm/311 MeSH D010267 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 etiology.
Neoplasms can develop from parapsoriasis.[1] For example, it can develop into cutaneous T-cell lymphoma.
The word "Parapsoriasis" was formed in 1902.[2]
Classification
The parapsoriasis group, 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.[2] However, the following classification scheme is now generally accepted:[3]:450
- Large-plaque parapsoriasis
- Small-plaque parapsoriasis
- Pityriasis lichenoides
- Lymphomatoid papulosis
