In this report, we learn regarding the symptoms and causes of psoriasis, according to the “dermnetnz” website.

Causes of psoriasis
Psoriasis is multifactorial and is classified as an autoimmune hereditary skin disease that involves a complex interaction between the innate and adaptive immune systems.
About one-third of psoriasis patients have family members with psoriasis
Symptoms of psoriasis
Psoriasis usually appears as symmetrically distributed red, scaly plaques with well-defined edges. The crust is usually silvery white, except in skin folds where the plaques often appear shiny with a moist peeling surface.
The most common sites are the scalp, elbows, and knees, but any part of the skin can be affected. The plaques are usually very persistent without treatment.
Itching is mostly mild but may be severe in some patients, leading to scratching and increased skin marks. Painful skin cracks or fissures may occur, especially on the palms.
When psoriasis plaques go away, they may leave brown or pale marks (post-inflammatory hypopigmentation or hyperpigmentation) that are expected to fade over several months.
