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]
