Psoriasis is not a dangerous or fatal disease. However, its course is usually very long, running into years and it varies from patient to patient. At the same time, it has a peculiar tendency to relapse after some period of time.

Psoriasis rarely causes long-term complications affecting vital body organs.
Psoriasis is more often a medico social disorder, especially when it shows up on the visible part of the body, such as on the face. There may also be feelings (sometimes with justification) that psoriasis has limited the patient’s career success because employers did not understand the nature of the disease. Patients may also deny themselves enjoyment of leisure activities because of embarrassment and fear of rejection, and the disease often makes patients feel unattractive to the opposite sex.
