As Becker's nevus is considered a benign lesion, treatment is generally not necessary except for cosmetic purposes. Shaving or trimming can be effective in removing unwanted hair, while electrology or laser hair removal may offer a longer-lasting solution. Different types of laser treatments may also be effective in elimination or reduction of hyperpigmentation, though the results of laser treatments for both hair and pigment reduction appear to be highly variable.

Phototherapy is considered a second-line treatment for vitiligo. Exposing the skin to light from UVB lamps is the most common treatment for vitiligo. The treatments can be done at home with an UVB lamp or in a clinic. The exposure time is managed so that the skin does not suffer overexposure. Treatment can take a few weeks if the spots are on the neck and face and if they existed not more than 3 years. If the spots are on the hands and legs and have been there more than 3 years, it can take a few months. Phototherapy sessions are done 2–3 times a week. Spots on a large area of the body may require full body treatment in a clinic or hospital. UVB broadband and narrowband lamps can be used, but narrowband ultraviolet picked around 311 nm is the choice. It has been constitutively reported that a combination of UVB phototherapy with other topical treatments improves re-pigmentation. However, some vitiligo patients may not see any changes to skin or re-pigmentation occurring. A serious potential side effect involves the risk of developing skin cancer, the same risk as an over-exposure to natural sunlight.

Ultraviolet light (UVA) treatments are normally carried out in a hospital clinic. Psoralen and ultraviolet A light (PUVA) treatment involves taking a drug that increases the skin's sensitivity to ultraviolet light, then exposing the skin to high doses of UVA light. Treatment is required twice a week for 6–12 months or longer. Because of the high doses of UVA and psoralen, PUVA may cause side effects such as sunburn-type reactions or skin freckling.

Narrowband ultraviolet B (NBUVB) phototherapy lacks the side-effects caused by psoralens and is as effective as PUVA. As with PUVA, treatment is carried out twice weekly in a clinic or every day at home, and there is no need to use psoralen.

In mild cases, vitiligo patches can be hidden with makeup or other cosmetic camouflage solutions. If the affected person is pale-skinned, the patches can be made less visible by avoiding tanning of unaffected skin.

Treatment is predominantly preventive. Avoidance of topical phenols and diets low in tyrosine may help. Replacement and repair of damaged tissue is also possible.

There does not yet exist a specific treatment for IP. Treatment can only address the individual symptoms.

"Narrowband UVB therapy as an effective treatment for Schamberg's disease."

This research article proposed that narrowband UVB therapy can be considered as a treatment for pigmented purpura. A study was done on a 33 year old man who had a 3 month history of widespread pigmented purpura. Oral prescription of prednisolone and topical ointment helped controlled the purpuric eruptions, but when the medication was stopped, the rash recurred. Researchers placed the patient on a UV therapy for 5 months. The patient showed signs of improvement, where new purpuric eruptions stopped and some of the pigmented purpura disappeared. However, when the dose of the UV therapy was decreased, the patient showed signs of recurrence. Researchers want to monitor the patient for two years to see if the purpuric eruptions will stop and they believe that this patient will have promising results.

"Successful treatment of generalized childhood Schamberg's disease with narrowband ultraviolet B therapy."

This research article demonstrated two cases where two children had purpuric rashes. The children were placed on UVB therapy and were monitored weekly for purpuric eruptions. One of the child received 10 treatments of UVB therapy, while the other child received 20 treatments. The child that received the 20 treatments did not show signs of purpuric eruptions and the skin lesions disappeared. However, the child that received the 10 treatments, showed signs of recurrence. Most of the rash disappeared, but some of it reappeared on the body. Researchers believe that the narrowband UVB therapy used on children has proven to remove and control the skin lesions.

There is no cure for Schamberg's disease; however, the itching can be controlled by a cortisone cream, and Colchicine treatment has been successfully used to prevent recurrence of the symptoms. This condition is not life-threatening or a major health concern. The only problem that patients will encounter is the itching and discoloration of the skin. It is recommended that patients take a vitamin C supplement to promote collagen production, which will help make the skin look and feel healthier. To prevent further irritation of the lesions, patients should avoid food with artificial colors and preservatives. Some people can be allergic to preservatives, which can cause the body to initiate an allergic reaction by further irritating those lesions. Several research studies have indicated that Schamberg's disease can be controlled and the number of lesions can be reduced with use a drug called aminaphtone. This drug helps improve capillary fragility and it prevents and controls the purpuric lesions.

A patient with Schamberg's disease can live a normal and healthy life. Since there is no proven cure for this condition, the patient will have to endure the lesions on his or her skin. With appropriate treatments, the condition may get better. Although the skin lesions are not life-threatening, it may cause a cosmetic concern for some individuals. Skin lesions may cause psychological discomfort, where patients may require reassurance to help with stress and anxiety. There are a few rare cases of T-cell lymphoma that has developed from Schamberg's disease.This is not a cause for concern, since the risk factors associated with Schamberg's disease are relatively low.

Mongolian spots usually resolve by early childhood and hence no treatment is generally needed if they are located in the sacral area. However, sometimes it may be required for extra sacral lesions to have surgical correction. Q-switched alexandrite lasers have been used for treatment. Good results are obtained if treatment is initiated before the age of 20 years. In a study done by the University of Tokyo, the effectiveness of the Q-switched alexandrite laser in treating Mongolian spots was evaluated. A retrospective study was done from April 2003 to September 2011. 16 patients, aged 14-55, were treated with Q-switched alexandrite laser. A good therapeutic outcome was achieved on the whole group, however two patients with sacral Mongolian spots suffered from inflammatory hyperpigmentation, and two patients got post inflammatory hypopigmentation after seven sessions of laser treatment.

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.

Discontinuing contact with the heat source is the initial treatment of erythema ab igne. If the area is only mildly affected with slight redness, the condition may resolve itself in a few months. If the condition is severe and the skin pigmented and atrophic, resolution is unlikely. In this case, there is a possibility that a squamous cell carcinoma or a neuroendocrine carcinoma such as a Merkel cell carcinoma may form. If there is a persistent sore that does not heal or a growing lump within the rash, a skin biopsy should be performed to rule out the possibility of skin cancer. If the erythema ab igne lesions demonstrate pre-cancerous changes, the use of 5-fluorouracil cream has been recommended. Abnormally pigmented skin may persist for years. Treatment with topical tretinoin or laser may improve the appearance.

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.

Excision biopsy is required to confirm the diagnosis of saree cancer. In many cases local excision with skin grafting is considered the appropriate treatment.

Different ways of wearing the petticoat may help saree-wearers to prevent saree cancer. Some such strategies are:

- Loosening the petticoat

- Changing the usual rope-like belt to broader ones that reduce pressure on the area

- Continuously changing the level at which the petticoat is tied

Oral propranolol appears to be the most effective treatment for reducing the size of capillary hemangiomas in children and is more effective than placebo, observation without intervention, or oral corticosteroids.

The management of a nevus depends on the specific diagnosis, however, the options for treatment generally include the following modalities:

The management of lipodermatosclerosis may include treating venous insufficiency with leg elevation and elastic compression stockings; in some difficult cases, the condition may be improved with the additional use of the fibrinolytic agent, stanozol. Fibrinolytic agents use an enzymatic action to help dissolve blood clots.

Stanozol is injected directly into the affected area, Venous Ablation has also been known to help circulation in patients.

Recent research has used induced pluripotent stem cells to study disease mechanisms in humans, and discovered that the reprogramming of somatic cells restores telomere elongation in dyskeratosis congenita (DKC) cells despite the genetic lesions that affect telomerase. The reprogrammed DKC cells were able to overcome a critical limitation in TERC levels and restored function (telomere maintenance and self-renewal). Therapeutically, methods aimed at increasing TERC expression could prove beneficial in DKC.

Treatment is supportive.

- The aplastic anemia and immunodeficiency can be treated by bone marrow transplantation.

- Supportive treatment for gastrointestinal complications and infections.

- Genetic counselling.

A 1991 report documented the cases of nine patients with both Becker's nevus and malignant melanoma. Of the nine melanomas, five were in the same body area as the Becker's nevus, with only one occurring within the nevus itself. As this was apparently the first documented co-occurrence of the two diseases, there is so far no evidence of higher malignancy rates in Becker's nevi versus normal skin. Nonetheless, as with any abnormal skin growth, the nevus should be monitored regularly and any sudden changes in appearance brought to the attention of one's doctor.

Haber syndrome is a cutaneous disorder of hyperpigmentation characterized by reticulated pigmentation of the person's skin. A rare genodermatosis, its key features include "rosacea-like facial eruption[,] reticulated hyperpigmentation of major flexures, comedones on the back and neck, and pitted facial scars."

Once chloracne has been identified, the primary action is to remove the patient and all other individuals from the source of contamination. Further treatment is symptomatic.

Secondary infections on severe or persistent lesions may need to be treated with oral antibiotics or isotretinoin. However, chloracne itself can be highly resistant to any treatment.

The course of the disease is highly variable. In some cases the lesions may disappear within two years or so; however, in other cases the lesions may be effectively permanent (mean duration of lesions in one 1984 study was 26 years, with some workers remaining disfigured over three decades after exposure).

Pigmentation disorders are disturbances of human skin color, either loss or reduction, which may be related to loss of melanocytes or the inability of melanocytes to produce melanin or transport melanosomes correctly.

Also known as "scoop", "scallop", or "shave" excisional biopsy, or "shave excision". A trend has occurred in dermatology over the last 10 years with the advocacy of a deep shave excision of a pigmented lesion An author published the result of this method and advocated it as better than standard excision and less time consuming. The added economic benefit is that many surgeons bill the procedure as an excision, rather than a shave biopsy. This save the added time for hemostasis, instruments, and suture cost. The great disadvantage, seen years later is the numerous scallop scars, and a very difficult to deal with lesions called a "recurrent melanocytic nevus". What has happened is that many "shave" excisions does not adequately penetrate the dermis or subcutanous fat enough to include the entire melanocytic lesion. Residual melanocytes regrow into the scar. The combination of scarring, inflammation, blood vessels, and atypical pigmented streaks seen in these recurrent nevus gives the perfect dermatoscopic picture of a melanoma. When a second physicians re-examine the patient, he or she has no choice but to recommend the reexcision of the scar. If one does not have access to the original pathology report, it is impossible to tell a recurring nevus from a severely dysplastic nevus or a melanoma. As the procedure is widely practiced, it is not unusual to see a patient with dozens of scallop scars, with as many as 20% of the scars showing residual pigmentation. The second issue with the shave excision is fat herniation, iatrogenic anetoderma, and hypertrophic scarring. As the deep shave excision either completely remove the full thickness of the dermis or greatly diminishing the dermal thickness, subcutanous fat can herniate outward or pucker the skin out in an unattractive way. In areas prone to friction, this can result in pain, itching, or hypertrophic scarring.

PVA usually has an underlying cause, attributed to existing skin diseases and disorders associated with a cutaneous lymphoma or inflammation. Mycosis fungoides is the common lymphoma believed to cause PVA, although it may be considered a precursor when the lymphoma is (hidden) and undiagnosed. Large plaque parapsoriasis is another common causes of PVA. Less common causes include autoimmune-related connective tissue diseases such as lupus, dermatomyositis and scleroderma. Dermatoses and those that are genetically inspired, called genodermatoses, may also be an underlying cause of PVA. Among them, xeroderma pigmentosum and Rothmund-Thomson syndrome (poikiloderma congenita) are thought to be the most prominent. Ingestion of substances containing arsenic, such as arsphenamine, has also been suggested as a least common cause. PVA can also be idiopathic (of unknown cause), as seen in a small number of cases.

Prosthetic replacement of missing teeth is possible using dental implant technology or dentures. This treatment can be successful in giving patients with anodontia a more aesthetically pleasing appearance. The use of an implant prosthesis in the lower jaw could be recommended for younger patients as it is shown to significantly improve the craniofacial growth, social development and self-image. The study associated with this evidence worked with individuals who had ectodermal dysplasia of varying age groups of up to 11, 11 to 18 and more than 18 years. It was noted that the risk of implant failure was significantly higher in patients younger than 18 years, but there is significant reason to use this methodology of treatment in those older. Overall the use of an implant-prosthesis has a considerable functional, aesthetic and psychological advantage when compared to a conventional denture, in the patients.

Therapies for metastatic melanoma include the biologic immunotherapy agents ipilimumab, pembrolizumab, and nivolumab; BRAF inhibitors, such as vemurafenib and dabrafenib; and a MEK inhibitor trametinib.
