Parapsoriasis

Classification according to ICD-10
L41	Parapsoriasis
ICD-10 online (WHO version 2019)

Parapsoriasis is an erythrosquamous, chronic skin disease which, due to its morphological similarity to psoriasis (psoriasis), was given this name by the French dermatologist Louis Anne Jean Brocq in 1902, originally provisionally. However, it has no nosological similarities to classical psoriasis. A distinction is made again between various individual diseases, of which parapsoriasis en plaques , which can occur on both small and large areas, especially on the extremities, and parapsoriasis guttata , a lymphocytic vasculitis, are important.

Inflammation and itching are relieved conservatively, as in psoriasis, with ointments. The so-called PUVA (psoralens + UVA), a photo-activated chemotherapy, is recommended as a further therapy . A confirmed parapsoriasis en plaques grandes should be monitored regularly, since a transition to a T-cell lymphoma of the entity Mycosis fungoides is possible in later years .
