Topical steroid cream or ointment may reduce the itch while waiting for the rash to resolve. Symptoms are usually minimal, but mild to severe itching may occur. Diagnosis is based on appearance and distribution of lesions. Lesions appear gradually and remit and recur spontaneously or with the appearance and resolution of triggers. Use ultraviolet (UV) light therapy, usually for moderate or severe psoriasis.
Pityriasis rosea is a skin rash. It is benign but may inflict substantial discomfort in certain cases. (Moderate itching due to skin over-dryness is much more common, especially if soap is used to cleanse the affected areas. 5 If the diagnosis is in doubt, tests may be performed to rule out similar conditions such as Lyme disease, ringworm, guttate psoriasis, nummular or discoid eczema, drug eruptions, other viral exanthems. Direct sunlight makes the lesions resolve more quickly. Aetna considers tanning beds for home UVB phototherapy not medically necessary. All ancillary signs of inflammation mostly resolved after the second treatment session. Note: Delrosso et al (2008) reported that an aggressive bath PUVA treatment is not substantially more effective in clearing chronic plaque-type psoriasis than a milder therapeutic approach. Phototherapy is the use of UV radiation in the treatment of skin disease. The first report on the use of the excimer laser to treat psoriasis goes back to 1997.
Xtrac laser therapy is used to treat psoriasis and vitiligo, as well as some forms of eczema.

Tazarotene may cause dryness and irritation of healthy skin. Patients Twenty-five patients with chronic plaque-type psoriasis. UV-B treatment and showed that it provides for faster clearing, less burning reactions, and longer periods of remission12 than conventional broadband UV-B phototherapy. One patient reported itching in both the narrowband UV-B and PUVA-treated skin areas. Narrowband UV-B produces superior clinical and histopathological resolution of moderate-to-severe psoriasis in patients compared with broad-band UV-B.
The pain characteristic of herpes zoster is thought to be due to irritation of the sensory nerve fibers in which the virus reproduces. Pain that persists for longer than one to three months after resolution of the rash is generally accepted as the sign of postherpetic neuralgia. Barriers which reduce UV exposure are effective in preventing skin cancers (clothes, hats, creams, lotions). Plaque psoriasis typically appears as raised areas of inflamed skin covered with silvery white scaly skin. The herald patch often is misdiagnosed as eczema.
