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.

There is no definitive cure for LS. Behavior change is part of treatment. The patient should minimize or preferably stop scratching LS-affected skin. Any scratching, stress or damage to the skin can worsen the disease. Scratching has been theorized to increase cancer risks. Furthermore the patient should wear comfortable clothes and avoid tight clothing, as it is a major factor in the severity of symptoms in some cases.

Topically applied corticosteroids to the LS-affected skin are the first-line treatment for lichen sclerosus in women and men, with strong evidence showing that they are "safe and effective" when appropriately applied, even over long courses of treatment, rarely causing serious adverse effects. They improve or suppress all symptoms for some time, which highly varies across patients, until it is required to use them again. Methylprednisolone aceponate has been used as a safe and effective corticosteroid for mild and moderate cases. For severe cases, it has been theorized that mometasone furoate might be safer and more effective than clobetasol.

Continuous usage of appropriate doses of topical corticosteroids is required to ensure symptoms stay relieved over the patient's life time. If continuously used, corticosteroids have been suggested to minimize the risk of cancer in various studies. In a prospective longitudinal cohort study of 507 women throughout 6 years, cancer occurred for 4.7% of patients who were only "partially compliant" with corticosteroid treatment, while it occurred in 0% of cases where they were "fully compliant". In a second study, of 129 patients, cancer occurred in 11% of patients, none of which were fully compliant with corticosteroid treatment. Both these studies however also said that a corticosteroid as powerful as clobetasol isn't necessary in most cases. In a prospective study of 83 patients, throughout 20 years, 8 patients developed cancer. 6 already had cancer at presentation and had not had treatment, while the other 2 weren't taking corticosteroids often enough. In all three studies, every single cancer case observed occurred in patients who weren't taking corticosteroids as often as the study recommended.

Continuous, abundant usage of emollients topically applied to the LS-affected skin is recommended to improve symptoms. They can supplement but not replace corticosteroid therapy. They can be used much more frequently than corticosteroids due to the extreme rarity of serious adverse effects. Appropriate lubrication should be used every time before and during sex in genital LS in order to avoid pain and worsening the disease. Some oils such as olive oil and coconut oil can be used to accomplish both the emollient and sexual lubrication function.

Recent studies have shown that topical calcineurin inhibitors such as tacrolimus can have an effect similar to corticosteroids, but its effects on cancer risks in LS are not conclusively known.

In males, it has been reported that circumcision can have positive effects, but does not necessarily prevent against further flares of the disease and does not protect against the possibility of cancer. Circumcision does not prevent or cure LS; in fact, "balanitis xerotica obliterans" in men was first reported as a condition affecting a set of circumcised men, by Stühmer in 1928.

All of these drugs may cause severe side effects, so the patient should be closely monitored by doctors. Once the outbreaks are under control, dosage is often reduced, to lessen side effects.

If skin lesions do become infected, antibiotics may be prescribed. Tetracycline antibiotics have a mildly beneficial effect on the disease and are sometimes enough for Pemphigus Foliaceus. In addition, talcum powder is helpful to prevent oozing sores from adhering to bedsheets and clothes. Wound care and treatment is often akin to that used in burn units, including careful use of dressings that don't stick to the wounds, etc.

If paraneoplastic pemphigus is diagnosed with pulmonary disease, a powerful cocktail of immune suppressant drugs is sometimes used in an attempt to halt the rapid progression of bronchiolitis obliterans, including methylprednisolone, ciclosporin, azathioprine, and thalidomide. Plasmapheresis may also be useful.

If not treated, pemphigus can be fatal, usually from overwhelming opportunistic infection of lesions. The most common treatment is the administration of oral steroids, especially prednisone, often in high doses. The side effects of corticosteroids may require the use of so-called steroid-sparing or adjuvant drugs. One of the most dangerous side effects of high dosage steroid treatments is intestinal perforations, which may lead to sepsis. Steroids and other medications being taken to treat Pemphigus may also mask the effects of the perforations. Patients on high dosages of oral steroids should closely monitor their GI health. As lesions are usually terribly painful, it is likely that pain medication can complicate and exacerbate the GI issues caused by steroids.

Carbon dioxide laser treatment is safe, effective and improves symptoms over a long time, but does not lower cancer risks.

Platelet rich plasma was reported to be effective in one study, producing large improvements in the patients' quality of life, with an average IGA improvement of 2.04 and DLQI improvement of 7.73.

Prurigo nodularis is very hard to treat, but current therapies include steroids, vitamins, cryosurgery, thalidomide and UVB light. In the event that staphylococcus or other infection is present, antibiotics have proven effective, but tend to cause more harm than good for this particular disease.

A physician may administer a strong dose of prednisone, which will almost immediately stop the itch/scratch cycle. However, cessation of steroids allows relapse to occur, usually within a few weeks. Horiuchi "et al" recently reported significant improvement in PN with antibiotic therapy.

Another drug a physician may administer is Apo-Azathioprine. Azathioprine, also known by its brand name Imuran, is an immunosuppressive drug used in organ transplantation and autoimmune diseases and belongs to the chemical class of purine analogues.

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.

Most treatments are topical or oral antifungal medications.

Topical agents include ciclopirox nail paint, amorolfine or efinaconazole. Some topical treatments need to be applied daily for prolonged periods (at least 1 year). Topical amorolfine is applied weekly. Topical ciclopirox results in a cure in 6% to 9% of cases; amorolfine might be more effective. Ciclopirox when used with terbinafine appears to be better than either agent alone.

Oral medications include terbinafine (76% effective), itraconazole (60% effective) and fluconazole (48% effective). They share characteristics that enhance their effectiveness: prompt penetration of the nail and nail bed, persistence in the nail for months after discontinuation of therapy. Ketoconazole by mouth is not recommended due to side effects. Oral terbinafine is better tolerated than itraconazole. For superficial white onychomycosis, systemic rather than topical antifungal therapy is advised.

Treatment is aimed at reducing itching and minimizing existing lesions because rubbing and scratching exacerbate LSC. The itching and inflammation may be treated with a lotions or steroid cream (such as triamcinolone or Betamethasone) applied to the affected area of the skin. Nighttime scratching can be reduced with sedatives and antihistamines. SSRIs can effectively reduce the scratching associated with obsessive psychosomatic behaviors.

You have to treat the primary cause or the exacerbation may persisist and reincide.

Topical steroids are the primary category of medications used to treat exfoliative dermatitis (ED). A sedative antihistamine may be a useful adjunct for pruritic patients, since it helps patients to sleep at night, thus limiting nocturnal scratching and excoriations. Antimicrobial agents often are used if an infection is suspected to be precipitating or complicating exfoliative dermatitis. Other drugs specifically indicated for management of underlying cause of exfoliative dermatitis may be necessary.

Chemical (keratolytic) or surgical debridement of the affected nail appears to improve outcomes.

As of 2014 evidence for laser treatment is unclear as the evidence is of low quality and varies by type of laser.

As of 2013 tea tree oil has failed to demonstrate benefit in the treatment of onychomycosis. A 2012 review by the National Institutes of Health found some small and tentative studies on its use.

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.

Ciclosporin is an immunosuppressive agent most often used in organ transplantation that has demonstrated to be effective with skin disorders. It functions by lessening production of autoantibodies and therefore diminishing the development of blisters and erosions. The mechanism of action is by inhibiting the production of T lymphocytes and lymphokines.

Azathioprine is a steroid-sparing agent used in combination with Prednisone. It functions by inhibiting RNA and DNA synthesis.

Leukoedema is a harmless condition, and no treatment is indicated. People may be alarmed by the appearance and benefit from reassurance.

Improvement or stabilization of the condition has been reported with topical and intralesional corticosteroids, antibiotics, hydroxychloroquine, topical and oral immunomodulators, tacrolimus, and most recently, 5-alpha-reductase inhibitors. In one study, the use of anti-androgens (finasteride or dutasteride) was associated with improvement in 47% and stabilization in 53% of patients

Since most cases cause no symptoms, reassuring the person affected that the condition is entirely benign is usually the only treatment.

When symptoms are present, topical anesthetics can be used to provide temporary relief. Other medications that have been used to manage the symptoms include antihistamines, corticosteroids or anxiolytics, but these drugs have not been formally assessed for efficacy in geographic tongue. If some foods exacerbate or trigger the symptoms, then cutting these foods out of the diet may benefit. One uncontrolled trial has shown some benefit in controlling the symptoms of geographic tongue.

As mentioned above, primary cicatricial alopecias are classified by the predominant type of inflammatory cells that attack the hair follicles: i.e., lymphocytes, neutrophils, or mixed inflammatory cells. Treatment strategies are different for each subtype and detailed treatment options are beyond the scope of this discussion. However, certain general principals are reviewed below.

Treatment of the lymphocytic group of cicatricial alopecias (including lichen planopilaris, frontal fibrosing alopecia, central centrifugal alopecia, and pseudopelade (Brocq) involves use of anti-inflammatory medications. The goal of treatment is to decrease or eliminate the lymphocytic inflammatory cells that are attacking and destroying the hair follicle. Oral medications may include hydroxychloroquine, doxycycline, mycophenolate mofetil, cyclosporine, or corticosteroids. Topical medications may include corticosteroids, tacrolimus, pimecrolimus, or Derma-Smoothe/FS scalp oil. Triamcinolone acetonide, a corticosteroid, may be injected into inflamed, symptomatic areas of the scalp.

Treatment of the neutrophilic group of cicatricial alopecias (folliculitis decalvans, tufted folliculitis) is directed at eliminating the predominant pathogenic microbes that are invariably involved in the inflammatory process. Oral antibiotics are the mainstay of therapy, and topical antibiotics may be used to supplement the oral antibiotics. In dissecting cellulitis, pathogenic microbes are not usually present. Isotretinoin in small doses may be helpful in treating dissecting cellulitis.

Treatment of the mixed group of cicatricial alopecias (folliculitis keloidalis) may include antimicrobials, isotretinoin, and anti-inflammatory medications.

You should discuss any treatment with your dermatologist, who will also explain potential side effects, as well as laboratory tests that are needed before starting treatment and sometimes are monitored during treatment.

The course of cicatricial alopecia is usually prolonged. Treatment is continued until the symptoms and signs of scalp inflammation are controlled, and progression of the condition has been slowed. In other words, itching, pain, tenderness, and burning have cleared, scalp redness, scaling, and/or pustules are no longer present, and the progression of the hair loss has been stopped or slowed. Treatment may then be stopped. Unfortunately, the cicatricial alopecias may reactivate after a quiet period and treatment may have to be repeated.

Surgical treatment for cosmetic benefit is an option in some cases after the disease has been inactive for one to two or more years. Hair restoration surgery or scalp reduction may be considered in these instances.

Treatment for fiddler’s neck is unnecessary if it is painless and shows minimal swelling, particularly since minor cases are taken as a mark of pride. But fiddler’s neck may lead to worse disorders. The primary methods of treatment involve adjustments to playing of the instrument:

- good hygiene for the affected area and for the instrument

- use of a clean cotton cloth that is changed frequently

- use of a shoulder rest to reduce pressure below the jaw

- a suitable chin rest, especially one carved or molded for the individual

- Covering or changing potentially allergenic materials on the instrument.

- shifting the chin rest to the center of the body over the tailpiece

- smoothing coarse surfaces to reduce abrasion

- for males, growing a beard to avoid folliculitis

Surgery is necessary for sialolithiasis, parotid tumors, and cysts. Cervical lymph nodes that are larger than 1 cm must be biopsied. Connective tissue can be removed by excision when a non-inflamed mass is large, and there is generally little recurrence. Infections should be treated conservatively, and causative species should be identified through smear and culture for appropriate antibiotic selection. Reduction of playing time may be helpful for cases without inflammation, but in 30% of cases this did not improve the symptoms.

The condition may disappear over time, but it is impossible to predict if or when this may happen.

When the appearance is caused by heat, the lesion is usually completely reversible within a few weeks if the smoking habit is stopped. This is the case even if the condition has been present for decades. Without stopping smoking, spontaneous remission of the lesion is unlikely. If the lesion persists despite stopping smoking, this is usually then considered to be a true leukoplakia rather than a reactionary keratotis, and may trigger the decision to carry out a biopsy to confirm the diagnosis. Since this condition almost always develops in the setting of long term heavy smoking, it usually indicates the need for regular observation for cancers associated with smoking, e.g. lung cancer.

The classification of exfoliative dermatitis into Wilson-Brocq (chronic relapsing), Hebra or pityriasis rubra (progressive), and Savill (self-limited) types may have had historical value, but it currently lacks pathophysiologic or clinical utility.

Hair will not regrow once the follicle is destroyed. However, it may be possible to treat the inflammation in and around surrounding follicles before they are destroyed, and for this reason it is important to begin treatment as early as possible to halt the inflammatory process. Minoxidil solution (2% or 5%) applied twice daily to the scalp may be helpful to stimulate any small, remaining, unscarred follicles. The progression of hair loss is unpredictable. In some cases, progression is slow and there is always sufficient hair remaining to cover the affected scalp areas; in other cases, progression can be rapid and extensive.
