Psoriasis may be classified as mild, moderate or severe depending upon the amount of skin involved and the effect on an individual’s quality of life. The severity of psoriasis varies from case to case. In some cases, individuals with psoriasis may experience abnormalities affecting the fingernails, toenails, and the soft tissues inside the mouth. The plaques may be intensely itchy (pruritic) or sore. These patches may be referred to as papules or plaques and most often affect the scalp, elbows, knees, hands, feet and/or lower back. Psoriasis is a chronic, inflammatory skin disease characterized by dry, reddish (erythematous), thickened patches of skin that are covered with silvery-gray scales. Comparisons may be useful for a differential diagnosis. Symptoms of the following disorders can be similar to those of pityriasis rosea. However, people with darker skin may have residual dark spots at sites of inflammation which can last for many months before resolution. Pityriasis rosea eventually goes away on its own, even without treatment, and usually does not leave any scars or permanent marks. The rash usually lasts one to three months in approximately 80 percent of cases. In some people, the rash does not itch in other people, the rash may be extremely itchy (pruritic). In rare cases, the rash may be isolated (localized) to one specific area of the body. Less often, other areas of the body may become involved. Although the back, chest and stomach are most commonly affected, the rash may spread to affect the arms, legs and neck. In individuals with darker skin, the rash may be gray, dark brown or black. Over the next few days or weeks, multiple smaller scaly, pink or red spots will develop.
#ROAD RASH MEDICAL TERM PATCH#
Often the herald patch is misdiagnosed as ring worm (tinea corporis). A herald patch is a slightly raised plaque that is usually between 2 to 4 inches large. When located on the back the herald patch may go undetected before appearance of the generalized rash. Initially, affected individuals develop a herald patch, which is a single scaly red patch, usually on the back, chest or stomach. Sometimes there is no history of preceding illness before the rash appears. Such symptoms can include fever, headache, stuffy nose, sore throat and fatigue. In many cases, the characteristic rash associated with pityriasis rosea is preceded by vague, nonspecific symptoms similar to those seen with a viral upper respiratory infection. 5 Myths About Orphan Drugs and the Orphan Drug Act.COVID-19 Rapid Response Leadership Series.Information on Clinical Trials and Research Studies.
