Currently there is no specific treatment for this condition. Management is supportive.

Café au lait spots can be removed with lasers. Results are variable as the spots are often not completely removed or can come back after treatment. Often, a test spot is treated first to help predict the likelihood of treatment success.

It is suggested that, once diagnosed, individuals be routinely followed by a cardiologist, endocrinologist, dermatologist, and other appropriate specialties as symptoms present.

It is recommended that those with the syndrome who are capable of having children seek genetic counseling before deciding to have children. As the syndrome presents frequently as a "forme fruste" (incomplete, or unusual form) variant, an examination of all family members must be undertaken. As an autosomal dominant trait there is a fifty percent chance with each child that they will also be born with the syndrome. Although fully penetrant, since the syndrome has variable expressivity, one generation may have a mild expression of the syndrome, while the next may be profoundly affected.

Once a decision to have children is made, and the couple conceives, the fetus is monitored during the pregnancy for cardiac evaluation. If a gross cardiac malformation is found, parents receive counseling on continuing with the pregnancy.

Other management is routine care as symptoms present:

1. For those with endocrine issues (low levels of thyrotopin [a pituitary hormone responsible for regulating thyroid hormones], follicle stimulating hormone) drug therapy is recommended.

2. For those who are disturbed by the appearance of lentigines, cryosurgery may be beneficial. Due to the large number of lentigines this may prove time consuming. An alternative treatment with tretinoin or hydroquinone creams may help.

3. Drug therapies for those with cardiac abnormalities, as those abnormalities become severe enough to warrant the use of these therapies. ECG's are mandatory prior to any surgical interventions, due to possible arrythmia.

No curative treatment against EV has been found yet. Several treatments have been suggested, and acitretin 0.5–1 mg/day for 6 months’ duration is the most effective treatment owing to antiproliferative and differentiation-inducing effects.

Interferons can also be used effectively together with retinoids.

Cimetidine was reported to be effective because of its depressing mitogen-induced lymphocyte proliferation and regulatory T cell activity features. A report by Oliveira "et al." showed that cimetidine was ineffective. Hayashi "et al." applied topical calcipotriol to a patient with a successful result.

As mentioned, various treatment methods are offered against EV; however, most importantly, education of the patient, early diagnosis, and excision of the tumoral lesions take preference to prevent the development of cutaneous tumors.

In itself, NSML is not a life-threatening diagnosis, most people diagnosed with the condition live normal lives. Obstructive cardiomyopathy and other pathologic findings involving the cardiovascular system may be a cause of death in those whose cardiac deformities are profound.

Treatment for the disease itself is nonexistent, but there are options for most of the symptoms. For example, one suffering from hearing loss would be given hearing aids, and those with Hirschsprung’s disorder can be treated with a colostomy.

TSC typically affects multiple organ systems and manifests differently in each patient and in different stages of the life course. Drug therapy, surgery, and other interventions can be effective in managing some of the manifestations and symptoms of TSC.

In the United States, the Food and Drug Administration has approved several drugs for managing some of the major manifestations of TSC. The antiepileptic medication vigabatrin was approved in 2009 for treatment of infantile spasms and was recommended as first-line therapy for infantile spasms in children with TSC by the 2012 International TSC Consensus Conference. Adrenocorticotropic hormone was approved in 2010 to treat infantile spasms. Everolimus was approved for treatment of TSC-related tumors in the brain (subependymal giant cell astrocytoma) in 2010 and in the kidneys (renal angiomyolipoma) in 2012. Everolimus also showed evidence of effectiveness at treating epilepsy in some people with TSC. In 2017, the European Commission approved everolimus for treatment of refractory partial-onset seizures associated with TSC.

Neurosurgical intervention may reduce the severity and frequency of seizures in TSC patients. Embolization and other surgical interventions can be used to treat renal angiomyolipoma with acute hemorrhage. Surgical treatments for symptoms of lymphangioleiomyomatosis (LAM) in adult TSC patients include pleurodesis to prevent pneumothorax and lung transplantation in the case of irreversible lung failure.

Other treatments that have been used to treat TSC manifestations and symptoms include a ketogenic diet for intractable epilepsy and pulmonary rehabilitation for LAM.

Surgical excision is the standard of care. Some individuals advocate the use of hair removal laser for the treatment of congenital nevi. While this is likely safe and effective for small congenital nevus, laser removal for larger lesions might pose a liability for the laser surgeon if malignancy developed from a deep (dermal) component of the nevus that is not reached by the laser. Repigmentation after laser treatment of congenital nevi or superficial curettage supports this concern.

Many are surgically removed for aesthetics and relief of psychosocial burden, but larger ones are also excised for prevention of cancer, although the benefit is impossible to assess for any individual patient. Proliferative nodules are usually biopsied and are regularly but not systematically found to be benign. Estimates of transformation into melanoma vary from 2-42% in the literature, but are most commonly considered to be at the low end of that spectrum due to early observer bias.

The primary treatment of TEN is discontinuation of the causative factor(s), usually an offending drug, early referral and management in burn units or intensive care units, supportive management, and nutritional support.

Current literature does not convincingly support use of any adjuvant systemic therapy. Initial interest in Intravenous immunoglobulin (IVIG) came from research showing that IVIG could inhibit Fas-FasL mediated keratinocyte apoptosis in vitro. Unfortunately, research studies reveal conflicting support for use of IVIG in treatment of TEN. Ability to draw more generalized conclusions from research to date has been limited by lack of controlled trials, and inconsistency in study design in terms of disease severity, IVIG dose, and timing of IVIG administration.

Larger, high quality trials are needed to assess the actual benefit of IVIG in TEN.

Numerous other adjuvant therapies have been tried in TEN including, corticosteroids, cyclosporin, cyclophosphamide, plasmapheresis, pentoxifylline, N-acetylcysteine, ulinastatin, infliximab, and Granulocyte colony-stimulating factors (if TEN associated-leukopenia exists). There is mixed evidence for use of corticosteriods and scant evidence for the other therapies.

Most birthmarks are harmless and do not require treatment. Pigmented marks can resolve on their own over time in some cases. Vascular birthmarks may require reduction or removal for cosmetic reasons. Treatments include administering oral or injected steroids, dermatological lasers to reduce size and/or color, or dermatologic surgery.

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.

Resection of the polyps is required only if serious bleeding or intussusception occurs. Enterotomy is performed for removing large, single nodules. Short lengths of heavily involved intestinal segments can be resected. Colonoscopy can be used to snare the polyps if they are within reach.

Westerhof syndrome is a cutaneous condition inherited in an autosomal dominant fashion, characterized by congenital hypopigmented macules.

If the Hirschsprung's disease is treated in time, ABCD sufferers live otherwise healthy lives. If it is not found soon enough, death often occurs in infancy. For those suffering hearing loss, it is generally regressive and the damage to hearing increases over time. Digestive problems from the colostomy and reattachment may exist, but most cases can be treated with laxatives. The only other debilitating symptom is hearing loss, which is usually degenerative and can only be treated with surgery or hearing aids.

Throughout the years, many different treatments have been tried for morphea including topical, intra-lesional, and systemic corticosteroids. Antimalarials such as hydroxychloroquine or chloroquine have been used. Other immunomodulators such as methotrexate, topical tacrolimus, and penicillamine have been tried. Some have tried prescription vitamian-D with success. Ultraviolet A (UVA) light, with or without psoralens have also been tried. UVA-1, a more specific wavelength of UVA light, is able to penetrate the deeper portions of the skin and thus, thought to soften the plaques in morphea by acting in two fashions:

- 1) by causing a systemic immunosuppression from UV light.

- 2) by inducing enzymes that naturally degrade the collagen matrix in the skin as part of natural sun-aging of the skin.

As with all of these treatments for morphea, the difficulty in assessing outcomes in an objective way has limited the interpretation of most studies involving these treatment modalities.

The discoloration usually disappears spontaneously over a period of several months after giving birth or stopping the oral contraceptives or hormone replacement therapy.

Treatments are often ineffective as it comes back with continued exposure to the sun. Assessment by a dermatologist will help guide treatment. This may include use of a Woods lamp to determine depth of the melasma pigment. Treatments to hasten the fading of the discolored patches include:

- Topical depigmenting agents, such as hydroquinone (HQ) either in over-the-counter (2%) or prescription (4%) strength. HQ is a chemical that inhibits tyrosinase, an enzyme involved in the production of melanin.

- Tretinoin, an acid that increases skin cell (keratinocyte) turnover. This treatment cannot be used during pregnancy.

- Azelaic acid (20%), thought to decrease the activity of melanocytes.

- Tranexamic acid by mouth has shown to provide rapid and sustained lightening in melasma by decreasing melanogenesis in epidermal melanocytes.

- Cysteamine hydrochloride (5%) over-the-counter. Mechanism of action seems to involve inhibition of melanin synthesis pathway

- Flutamide (1%)

- Chemical peels

- Microdermabrasion to dermabrasion (light to deep)

- Galvanic or ultrasound facials with a combination of a topical crème/gel. Either in an aesthetician's office or as a home massager unit.

- Laser but not IPL (IPL can make the melasma darker)

Evidence-based reviews found that the most effective therapy for melasma includes a combination on topical agents.

In all of these treatments the effects are gradual and a strict avoidance of sunlight is required. The use of broad-spectrum sunscreens with physical blockers, such as titanium dioxide and zinc dioxide is preferred over that with only chemical blockers. This is because UV-A, UV-B and visible lights are all capable of stimulating pigment production.

Patients should avoid other precipitants including hormonal triggers.

Cosmetic camouflage can also be used to hide melasma.

There are a wide range of depigmenting treatments used for hyperpigmentation conditions, and responses to most are variable.

Most often treatment of hyperpigmentation caused by melanin overproduction (such as melasma, acne scarring, liver spots) includes the use of topical depigmenting agents, which vary in their efficacy and safety, as well as in prescription rules. Several are prescription only in the US, especially in high doses, such as hydroquinone, azelaic acid, and koijic acid. Some are available without prescription, such as niacinamide, or cysteamine hydrochloride. Hydroquinone was the most commonly prescribed hyperpigmentation treatment before the long-term safety concerns were raised, and the use of it became more regulated in several countries and discouraged in general by WHO. For the US only 2% is at present sold over-the-counter, and 4% needs prescription. In the EU hydroquinone was banned from cosmetic applications. Treatments that do not involve topical agents are also available, including fraction lasers and dermabrasion.

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

Jaffe–Campanacci syndrome is one of the disorders associated with café au lait macules (CALMs). Presentations may include Intellectual Disability, disseminated non-ossifying fibromas of the long bones and jaw, hypogonadism or cryptorchidism, or giant cell granulomas of the jaw.

It was characterized in 1958 and 1983.

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.

Terminal osseous dysplasia with pigmentary defects is a cutaneous condition characterized by hyperpigmented, atrophic facial macules.

It has been associated with "FLNA".

Café au lait spots are usually present at birth, permanent, and may grow in size or increase in number over time.

Cafe au lait spots are themselves benign and do not cause any illness or problems. However, they may be associated with syndromes such as Neurofibromatosis Type 1 and McCune-Albright syndrome.

The size and shape of the spots do not have any meaning or implications with regards to diagnosis of associated syndromes.

Dyschromatosis universalis hereditaria is a rare genodermatosis characterized by reticulate hyper- and hypo- pigmentated macules in a generalized distribution.

Both autosomal dominant and recessive inheritance have been reported with the disorder.

Pitt–Hopkins syndrome is a rare genetic disorder characterized by developmental delay, a wide mouth, distinctive facial features, and intermittent hyperventilation followed by apnea. It is associated with an abnormality within chromosome 18: specifically, it is caused by an insufficient expression of the TCF4 gene.

Reticulate acropigmentation of Kitamura consists of linear palmar pits and pigmented macules 1 to 4 mm in diameter on the volar and dorsal aspects of the hands and feet, usually inherited in an autosomal-dominant fashion.
