Many different treatments have been reported for cutaneous lichen planus, however there is a general lack of evidence of efficacy for any treatment. Treatments tend to be prolonged, partially effective and disappointing. The mainstay of localized skin lesions is topical steroids. Additional treatments include retinoids, such as acitretin, or sulfasalazine. Narrow band UVB phototherapy or systemic PUVA therapy are known treatment modalities for generalized disease.

Reassurance that the condition is benign, elimination of precipitating factors and improving oral hygiene are considered initial management for symptomatic OLP, and these measures are reported to be useful. Treatment usually involves topical corticosteroids (such as betamethasone, clobetasol, dexamethasone, and triamcinolone) and analgesics, or if these are ineffective and the condition is severe, the systemic corticosteroids may be used. Calcineurin inhibitors (such as pimecrolimus, tacrolimus or cyclosporin) are sometimes used.

Treatments for tinea versicolor include:

- Topical antifungal medications containing selenium sulfide are often recommended. Ketoconazole (Nizoral ointment and shampoo) is another treatment. It is normally applied to dry skin and washed off after 10 minutes, repeated daily for two weeks. Ciclopirox (Ciclopirox olamine) is an alternative treatment to ketoconazole, as it suppresses growth of the yeast "Malassezia furfur". Initial results show similar efficacy to ketoconazole with a relative increase in subjective symptom relief due to its inherent anti-inflammatory properties. Other topical antifungal agents such as clotrimazole, miconazole, terbinafine, or zinc pyrithione can lessen symptoms in some patients. Additionally, hydrogen peroxide has been known to lessen symptoms and, on certain occasions, remove the problem, although permanent scarring has occurred with this treatment in some sufferers. Clotrimazole is also used combined with selenium sulfide.

- Oral antifungals including ketoconazole or fluconazole in a single dose, or ketoconazole for seven days, or itraconazole can be used. The single-dose regimens, or pulse therapy regimens, can be made more effective by having the patient exercise 1–2 hours after the dose, to induce sweating. The sweat is allowed to evaporate, and showering is delayed for a day, leaving a film of the medication on the skin.

Currently there is no cure for actinic prurigo, and treatment focuses on relieving the dermatologic symptoms, by way of topical steroid creams or systemic immunosuppressants.

Prescribed treatments include:

- topical creams such as Tacrolimus and Betamethasone.

- systemic immunosuppressants such as Prednisone.

- In some cases, Thalidomide has proven to be effective in controlling the symptoms of actinic prurigo.

All patients with AP are encouraged to minimize sun exposure, and to use strong sunscreen throughout the year, and even on cloudy or overcast days, as UVA light, unlike UVB light, is able to penetrate cloud cover and remains constant throughout the day.

Alternative treatment methods might include UV Hardening, Meditation and/or cognitive behavioral therapy. UV-A desensitization phototherapy has also been shown to be effective in cases.

Generally, lichen nitidus is asymptomatic and self-limited; therefore, no treatment is required. However, if persistent pruritus is present, or the appearance “...interferes with daily activities or outlook...” topical glucocorticoids may be tried. If the disease process is symptomatic, generalized and extensive, oral glucocorticoids may be indicated. Other reported treatments include PUVA, UVA/UVB phototherapy, astemizole, acitretin, and etretinate.

When appears with sun/humidity; air conditioning (cool dry air) reduces swelling and discomfort.

There is no effective treatment for this condition. It has been reported that clearance of lesions can be done with melphalan and cyclophosphamide alone or in combination with prednisone. Both isotretinoin and etretinate have also been shown to improve the conditions. All medications listed can cause adverse symptoms, with isotretinoin and etretinate particularly dangerous since they are both teratogens. Other attempted treatments include interferon-alpha, cyclosporine, PUVA photochemotherapy, electron-beam therapy, IVIg, and dermabrasion. However, the overall prognosis for the disease is poor. There are reported instances of remission of the disease when treated with a combination of Revlimid and Dexamethasone over a 24-month period.

Treatments include class I topical steroids (clobetasol, halobetasol, etc.) which in some studies have proven to be equally effective as systemic, or pill, therapy and somewhat safer. However, in difficult-to-manage or widespread cases, systemic prednisone and powerful steroid-free immunosuppressant medications, such as methotrexate, azathioprine or mycophenolate mofetil, may be appropriate. Antibiotics such as tetracycline or erythromycin may also control the disease, particularly in patients who cannot use corticosteroids. The anti-CD20 monoclonal antibody rituximab has been found to be effective in treating some otherwise refractory cases of bullous pemphigoid.

IgA-mediated pemphigoid can often be difficult to treat even with usually effective medications such as rituximab.

Sweating causes lesions to form, but lesions aggravated by sweat usually return to "normal" fairly quicklyavoiding sweat is not a reason to avoid exercise. Minor outbreaks can be controlled with prescription strength topical cortisone creams. More severe eruptions usually clear up after treatment for one to three months with Accutane or tetracycline. If these fail or the outbreak is severe, PUVA phototherapy treatments, antifungal pills and cortisone injections are alternatives.

Some research has suggested a correlation of Grover's disease with mercury toxicity in which case Dimercaptosuccinic acid might help.

Reported treatments include topical agents, dermabrasion, cryotherapy, laser therapy, and surgical excision. These therapies have a high failure rate because of incomplete relief of symptoms, scarring, or recurrence .

Though similar in appearance, ILVEN will not respond to therapies known to affect psoriasis. ILVEN can be very difficult to live with but can be treated. The most effective method is full-thickness excision of the lesion. CO2 Laser Surgery can resurface the skin to give a flat, smoother and more normal appearance, but does not remove the lesion.

The basis of management is to find and correct the underlying cause. Many times cats with EGC will respond to treatment with corticosteroids or to ciclosporin.

Because the eruption is transient and self-limiting, no treatment is indicated.

Generally, PLE resolves without treatment; also, PLE irritations generally leave no scar. However, in severe cases the use of steroids is necessary to help reduce inflammation and increase quality of life of the patient. There are also other therapies for patients who are severely impacted, such as light therapy to harden the skin's surface.

A single case report suggested that oral dapsone may be useful for prevention. However, the efficacy of oral dapsone as prevention has not been demonstrated very clearly until now.

Phytophotodermatitis can be prevented by staying indoors after handling the above substances. However, the primary triggering mechanism is UV-A radiation (320–380 nm) which windows are not guaranteed to filter out.

Many different topical and oral medications can be used to treat the inflammatory reaction of phytophotodermatitis. A dermatologist may also prescribe a bleaching cream to help treat the hyperpigmentation and return the skin pigmentation back to normal. If they do not receive treatment, the affected sites may develop permanent hyperpigmentation or hypopigmentation.

NEH is self-limited and usually resolves without treatment. In the overwhelming majority of the cases, spontaneous resolution occurs within 1–2 weeks.

However, if the patient developed NEH after chemotherapy, the offending cytotoxic drug has to be discontinued, and the patient must avoid this particular cytotoxic drug in the future, because NEH usually re occurs upon re exposure to the same cytotoxic drug.

Despite the fact that NEH is self limited and usually resolves without treatment, some researchers use treatment, mainly systemic corticosteroids, although the efficacy of such a therapy has not been demonstrated in a large randomised controlled clinical trial until now.

With only a small number of case reports, treatment can be difficult and focuses primarily on axillary disease and specific symptoms. First line treatment includes topical and intalesional glucocorticoids. Specific therapies include estrogen hormones and steroid creams. Use of tretinoin reduced pruritic and axillary papules in one study. However, irritation limited drug use to short term only. Clindamycin mixed with pimecrolimus cream and benzoyl peroxide was also effective. Clindamycin is used to inhibit bacterial growth and is used when treating staphylococcal and streptococcal infections.

Usually, a common form of treatment for the condition is a type of hand cream which moisturises the hard skin. However, currently the condition is incurable.

Identifying and treatment the underlying malignancy constitutes an uptime approach. Topical 5-fluorouracil may occasionally be help, as may oral retinoids, topical steroids, vitamin A acid, urea, salicylic acid, podophyllotoxin, and cryodestruction employing liquid.

Treatment is symptomatic.

Treatment does not require a doctor's attention unless the case is severe, with most affected using a topical anti-itch cream (diphenhydramine) and a cortisone solution (hydrocortisone). Do not scratch the area, and avoid any clothing that may irritate the affected area; scratching will result in localized swelling and intense itching.

Upon exiting the water, prompt removal of swim clothing (while it is still wet) followed by a warm sea-water shower largely negates the risk of Seabather's eruption even in endemic areas. A hot freshwater shower with soap (paying particular attention to the hair and areas covered by the suit) is a somewhat less-effective alternative if uncontaminated seawater is unavailable. The contaminated swimsuit should be machine washed with laundry soap and dried in warm air.

Animals can be affected as well, and a cortisone solution for humans can be used on dogs.

The decision to observe or treat a nevus may depend on a number of factors, including cosmetic concerns, irritative symptoms (e.g., pruritus), ulceration, infection, and concern for potential malignancy.

Dapsone is an effective treatment in most people. Itching is typically reduced within 2–3 days. However, dapsone treatment has no effect on any intestinal damage that might be present.

Therefore, a strict gluten-free diet must also be followed, and this will usually be a lifelong requirement. This will reduce any associated intestinal damage and the risk of other complications. After some time on a gluten-free diet, the dosage of dapsone can usually be reduced or even stopped, although this can take many years.

Dapsone is an antibacterial, and its role in the treatment of DH, which is not caused by bacteria, is poorly understood. It can cause adverse effects on the blood, so regular blood monitoring is required.

Dapsone is the drug of choice. For individuals with DH unable to tolerate dapsone for any reason, alternative treatment options may include the following:

- colchicine

- lymecycline

- nicotinamide

- tetracycline

- sulfamethoxypyridazine

- sulfapyridine

Improvement usually parallels that of the cancer, whether surgical or chemotherapeutic. Generalization of the associated visceral malignancy may worsen the eruption.

This skin disease commonly affects adolescents and young adults, especially in warm and humid climates. The yeast is thought to feed on skin oils (lipids), as well as dead skin cells. Infections are more common in people who have seborrheic dermatitis, dandruff, and hyperhidrosis.

It can be treated with systemic antiviral drugs, such as aciclovir or valganciclovir. Foscarnet may also be used for immunocompromised host with Herpes simplex and acyclovir-resistant Herpes simplex.
