This patient is most likely to have plaque psoriasis, the most common form of psoriasis in young adults, with the average age of onset in the early twenties (Dunphy, Winland-Brown, Porter, & Thomas, 2015).)
The risk factors for the development of psoriasis are family history. One-third of all patients with psoriasis have a relative with the disease, as in the case study above. When a parent is affected the children have a tendency for an early onset of the condition. Not only that but when both parents are affected the chance increases to forty-one percent of the children having the condition. This patient had an upper respiratory infection prior to the outbreak of the rash; this predisposes her for an outbreak of psoriasis. Even though there is a genetic disposition of the offspring of the parents having the disease, the exact genetic cause is unknown. Research is ongoing regarding the genetic and environmental influences on the cellular effects of the disease (Dunphy, Winland-Brown, Porter, & Thomas, 2015).
