The goal of treatment is to improve the appearance of lesions since they are otherwise not serious and typically do not cause symptoms. Many treatment methods have been attempted however, complete removal is uncommon. No single treatment method has been shown to consistently work. Both medical and surgical treatments have been studied, each with variable success. Common destructive treatment methods include carbon dioxide lasers, dermabrasion, surgical excision, electrocoagulation and chemical peels. Many of these methods are very time consuming and require multiple treatment sessions.Carbon dioxide lasers are the most commonly practiced method; however, can cause thermal damage leading to scarring in the area. Medical therapies include topical atropine, topical retinoids and oral tranilast.

The most common adverse side effects include redness, skin discoloration and pain. Other side effects include blistering and scarring.

While chemotherapy, radiation therapy, curettage and liquid nitrogen have been effective in some cases of ameloblastoma, surgical resection or enucleation remains the most definitive treatment for this condition. In a detailed study of 345 patients, chemotherapy and radiation therapy seemed to be contraindicated for the treatment of ameloblastomas. Thus, surgery is the most common treatment of this tumor. Because of the invasive nature of the growth, excision of normal tissue near the tumor margin is often required. Some have likened the disease to basal cell carcinoma (a skin cancer) in its tendency to spread to adjacent bony and sometimes soft tissues without metastasizing. While rarely not a cancer that actually invades adjacent tissues, ameloblastoma is suspected to spread to adjacent areas of the jaw bone via marrow space. Thus, wide surgical margins that are clear of disease are required for a good prognosis. This is very much like surgical treatment of cancer. Often, treatment requires excision of entire portions of the jaw.

Radiation is ineffective in many cases of ameloblastoma. There have also been reports of sarcoma being induced as the result of using radiation to treat ameloblastoma. Chemotherapy is also often ineffective. However, there is some controversy regarding this and some indication that some ameloblastomas might be more responsive to radiation that previously thought.

Treatment is usually supportive treatment, that is, treatment to reduce any symptoms rather than to cure the condition.

- Enucleation of the odontogenic cysts can help, but new lesions, infections and jaw deformity are usually a result.

- The severity of the basal-cell carcinoma determines the prognosis for most patients. BCCs rarely cause gross disfigurement, disability or death .

- Genetic counseling

Management entails careful examination and monitoring for malignant degenerations. Surgical interventions can correct or minimize deformities.

Fatigue is a common symptom and affects the daily life of individuals with MS. Changes in lifestyle are usually recommended to reduce fatigue. These include taking frequent naps and implementing exercise. MS patients who smoke are also advised to stop. Pharmacological treatment include anti-depressants and caffeine. Aspirin has also been experimented with and from clinical trial data, MS patients preferred using aspirin as compared to the placebo in the test. One hypothesis is that aspirin has an effect on the hypothalamus and can affect the perception of fatigue through altering the release of neurotransmitters and the autonomic responses.

The treatment of spasticity ranges from physical activity to medication. Physical activity includes stretching, aerobic exercises and relaxation techniques. Currently, there is little understanding as to why these physical activities aid in relieving spasticity. Medical treatments include baclofen, diazepam and dantrolene which is a muscle-relaxant. Dantrolene has many side effects and as such, it is usually not the first choice in treatment of spasticity. The side effects include dizziness, nausea and weakness.

There is evidence that suppression of matrix metalloproteinase-2 may inhibit the local invasiveness of ameloblastoma, however, this was only demonstrated "in vitro". There is also some research suggesting that αβ integrin may participate in the local invasiveness of ameloblastomas.

A recent study discovered a high frequency of BRAF V600E mutations (15 of 24 samples, 63%) in solid/multicystic ameloblastoma. These data suggests drugs targeting mutant BRAF as potential novel therapies for ameloblastoma.

The different manifestations of Birt–Hogg–Dubé syndrome are controlled in different ways. The fibrofolliculomas can be removed surgically, through curettage, shave excision, skin resurfacing, or laser ablation; however, this is not a permanent solution as the tumors often recur. The renal and pulmonary symptoms are managed preventatively: CT scans, ultrasounds, or MRIs of the kidneys are recommended regularly, and family members are advised not to smoke. MRIs are the preferred method for surveillance of the kidneys in people with BHD because they do not carry the same risk of radiation complications as CT scans and are more sensitive than ultrasounds. Smokers with Birt–Hogg–Dubé have more severe pulmonary symptoms than non-smokers. Though nephrectomy is sometimes indicated, kidney tumors in cases of Birt–Hogg–Dubé are often removed without taking the whole kidney, in a procedure called partial nephrectomy. Knockout mouse studies have shown that administration of rapamycin may mitigate the effects of FLCN mutations on kidneys and improve renal cancer prognoses because of folliculin's interaction with the mTOR pathway.

Treatment begins with maximal surgical removal of the tumor. The addition of radiation to the entire neuraxis and chemotherapy may increase the disease-free survival. Some evidence indicates that proton beam irradiation reduces the impact of radiation on the cochlear and cardiovascular areas and reduces the cognitive late effects of cranial irradiation.

This combination may permit a 5-year survival in more than 80% of cases. The presence of desmoplastic features such as connective tissue formation offers a better prognosis. Prognosis is worse if the child is less than 3 years old, degree of resection is an inadequate , or if any CSF, spinal, supratentorial, or systemic spread occurs. Dementia after radiotherapy and chemotherapy is a common outcome appearing two to four years following treatment. Side effects from radiation treatment can include cognitive impairment, psychiatric illness, bone growth retardation, hearing loss, and endocrine disruption. Increased intracranial pressure may be controlled with corticosteroids or a ventriculoperitoneal shunt.

Chemotherapy is often used as part of treatment. Evidence of benefit, however, is not clear as of 2013. A few different chemotherapeutic regimens for medulloblastoma are used, but most involve a combination of lomustine, cisplatin, carboplatin, vincristine, or cyclophosphamide. In younger patients (less than 3–4 years of age), chemotherapy can delay, or in some cases possibly even eliminate, the need for radiotherapy. However, both chemotherapy and radiotherapy often have long-term toxicity effects, including delays in physical and cognitive development, higher risk of second cancers, and increased cardiac disease risks.

Confirmation of the clinical diagnosis is done with a skin biopsy. This is usually followed up with a wider excision of the scar or tumor. Depending on the stage, a sentinel lymph node biopsy is done, as well, although controversy exists around trial evidence for this procedure. Treatment of advanced malignant melanoma is performed from a multidisciplinary approach.

Various chemotherapy agents, including temozolomide, dacarbazine (also termed DTIC), immunotherapy (with interleukin-2 (IL-2) or interferon (IFN)), as well as local perfusion, are used by different centers. The overall success in metastatic melanoma is quite limited.

IL-2 (Proleukin) was the first new therapy approved (1990 Europe, 1992 USA) for the treatment of metastatic melanoma in 20 years. Studies have demonstrated that IL-2 offers the possibility of a complete and long-lasting remission in this disease, although only in a small percentage of patients. Intralesional IL-2 for in-transit metastases has a high complete response rate ranging from 40 to 100%.

By 2005 a number of new agents and novel approaches were under evaluation and showed promise.

In 2009 Clinical trial participation was considered the standard of care for metastatic melanoma.

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

Ongoing research is looking at treatment by adoptive cell transfer. For this purpose, application of prestimulated or modified T cells or dendritic cells is possible.

In terms of treatment/management one should observe what signs or symptoms are present and therefore treat those as there is no other current guideline. The affected individual should be monitored for cancer of:

- Thyroid

- Breast

- Renal

The Stehlin Foundation currently offers DSRCT patients the opportunity to send samples of their tumors free of charge for testing. Research scientists are growing the samples on nude mice and testing various chemical agents to find which are most effective against the individual's tumor.

Patients with advanced DSRCT may qualify to participate in clinical trials that are researching new drugs to treat the disease.

Treatment:wide excision taking 8mm normal tissue as this is locally malignant. For recurrence radiotherapy is given

Management Corticosteroids may be effective in some patients. Additional treatment options are beta-interferon or immunosuppressive therapy. Otherwise management is supportive and includes physiotherapy, occupational therapy and nutritional support in the later stages as patients lose their ability to eat.

Desmoplastic trichoepithelioma is benign tumor and can be managed safely with surgical removal, electrodesiccation and curettage.

Radiotherapy is the main choice of treatment for both SPB and extramedullary plasmacytoma, and local control rates of >80% can be achieved. This form of treatment can be used with curative intent because plasmacytoma is a radiosensitive tumor. Surgery is an option for extramedullary plasmacytoma, but for cosmetic reasons it is generally used when the lesion is not present within the head and neck region.

For symptomatic relief of carcinoid syndrome:

- Octreotide (a somatostatin analogue which decreases the secretion of serotonin by the tumor and, secondarily, decreases the breakdown product of serotonin (5-HIAA))

- Telotristat ethyl (Xermelo) along with a somatostatin analogue in patients not responding to somatostatin analogue monotherapy. It is a tryptophan hydroxylase inhibitor and reduces the production of serotonin.

- Peptide receptor radionuclide therapy (PRRT) with lutetium-177, yttrium-90 or indium-111 labeled to octreotate is highly effective

- Methysergide maleate (antiserotonin agent but not used because of the serious side effect of retroperitoneal fibrosis)

- Cyproheptadine (an antihistamine drug with antiserotonergic effects)

Alternative treatment for qualifying candidates:

- Surgical resection of tumor and chemotherapy (5-FU and doxorubicin)

- Endovascular, chemoembolization, targeted chemotherapy directly delivered to the liver through special catheters mixed with embolic beads (particles that block blood vessels), used for patients with liver metastases.

Surgical excision is the preferred method of treatment for benign glomus tumors.

For malignant teratomas, usually, surgery is followed by chemotherapy.

Teratomas that are in surgically inaccessible locations, or are very complex, or are likely to be malignant (due to late discovery and/or treatment) sometimes are treated first with chemotherapy.

The prognosis for DSRCT remains poor. Prognosis depends upon the stage of the cancer. Because the disease can be misdiagnosed or remain undetected, tumors frequently grow large within the abdomen and metastasize or seed to other parts of the body.

There is no known organ or area of origin. DSRCT can metastasize through lymph nodes or the blood stream. Sites of metastasis include the spleen, diaphragm, liver, large and small intestine, lungs, central nervous system, bones, uterus, bladder, genitals, abdominal cavity, and the brain.

A multi-modality approach of high-dose chemotherapy, aggressive surgical resection, radiation, and stem cell rescue improves survival for some patients. Reports have indicated that patients will initially respond to first line chemotherapy and treatment but that relapse is common.

Some patients in remission or with inoperable tumor seem to benefit from long term low dose chemotherapy, turning DSRCT into a chronic disease.

Recent case report studies suggest that treatment regimens which include a proteasome inhibitor drug, particularly bortezomib, and/or autologous stem-cell transplantation have improved pPCL survival. For example, 28 patients treated with a bortezomib-based induction regimen followed by autologous stem-cell transplantation and then a maintenance regimen of lenaldomide (an immunosuppressant related to thalidomide), bortezomib, and dexamethasone (a corticosteroid) has a progression free survival rate of 66% at 3 years and an overall survival rate of 73% at 4 years. In one study, patients receiving intensive chemotherapy plus autologous stem-cell transplantation had a median survival of 34 months while those receiving chemotherapy alone had a median survival of 11 months. Two other studies that included bortezomib in their chemotherapy regimens likewise found that the addition of autologous stem-cell transplantation improved results. Current recommendations for treating pPCL often include induction with a three drug regimen such as borezomib-lenalidomide-dexamethasone followed by autologous stem-cell transplantion and consolidation/maintenance with of combination of immunomodulator agents (e.g. thalidomide, lenalidomide, or pomalidomide) plus a proteasome inhibitor (bortezomib, ixazomib, or carfilzomib.

Osteochondromas are benign lesions and do not affect life expectancy. Complete excision of osteochondroma is curative and the reoccurrences take place when the removal of tumor is incomplete. Multiple reoccurrences in a well-excised lesion indicate that it may be malignant. The risk of malignant transformation takes place in 1–5% of individuals. If any symptoms of cancerous tumor takes place, then the patient should be evaluated by a bone specialist. No treatment is necessary for Solitary osteochondromas that are asymptomatic. Treatments for solitary osteochondroma are careful observation over time and taking regular x-rays to monitor any changes in the tumor. If the lesion is causing pain with activity, nerve or vessel impingement, or if the bone growth has fully matured and the presence of a large cartilage cap is prominent, then it is advised that the tumor be surgically removed.

Osteochondromas have a low rate of malignancy (<1%) and resection of the tumor is suggested if symptoms such as pain, limitation of movement, or impingement on nerves or vessels occur. Resection of the tumor also takes place when the tumor increases in size and progresses towards malignancy. During surgical resection, the entire lesion along with the cartilaginous cap should be removed to minimize any chances of reoccurrences. Surgical treatment becomes the sole treatment of choice if common complications such as fractures, symptoms of peripheral nerves such as paresthesia, paraplegia, peroneal neuropathy, and upper limb neuropathy take place. A prophylactic resection is suggested if the lesion lies next to a vessel.

Depending on the size and location of the tumor, the time it takes to return to normal daily activities varies between individuals. Limitation on some activities is advised if pain or discomfort persists after surgical excision.

As the end stage of multiple myeloma that has failed or broken through one or more therapeutic regimens, sPCL continues to be highly refractory to various treatment regimens (<50%), very short response times of these regiments, and poor overall survival rates (median survival of 2-8 to months). Patients with sPCL may have short-lived responses to treatment regimens (as communicated in case reports) that include bortezomid but there are no established therapeutic regimens that have clearly been shown to improve their overall or median survival.
