Surgical excision or cryosurgery is the treatment of choice. Treatment with antifungals has been considered ineffective, but the use of clofazimine and dapsone in patients with leprosy and lobomycosis has been found to improve the latter. This treatment regimen, with concomitant itraconazole, has been used to prevent recurrence after surgery.

Sulfonamides are the traditional remedies to paracoccidiodomycosis. They were introduced by Oliveira Ribeiro and used for more than 50 years with good results. The most-used sulfa drugs in this infection are sulfadimethoxime, sulfadiazine, and co-trimoxazole. This treatment is generally safe, but several adverse effects can appear, the most severe of which are the Stevens-Johnson syndrome and agranulocytosis. Similarly to tuberculosis treatment, it must be continued for up to three years to eradicate the fungus, and relapse and treatment failures are not unusual.

Antifungal drugs such as amphotericin B or itraconazole and ketoconazole are more effective in clearing the infection, but are limited by their cost when compared with sulfonamides.During therapy, fibrosis can appear and surgery may be needed to correct this. Another possible complication is Addisonian crisis. The mortality rate in children is around 7-10%.

Itraconazole given orally is the treatment of choice for most forms of the disease. Ketoconazole may also be used. Cure rates are high, and the treatment over a period of months is usually well tolerated. Amphotericin B is considerably more toxic, and is usually reserved for immunocompromised patients who are critically ill and those with central nervous system disease. Patients who cannot tolerate deoxycholate formulation of Amphotericin B can be given lipid formulations. Fluconazole has excellent CNS penetration and is useful where there is CNS involvement after initial treatment with Amphotericin B.

In the majority of immunocompetent individuals, histoplasmosis resolves without any treatment. Antifungal medications are used to treat severe cases of acute histoplasmosis and all cases of chronic and disseminated disease. Typical treatment of severe disease first involves treatment with amphotericin B, followed by oral itraconazole.

Liposomal preparations of amphotericin B are more effective than deoxycholate preparations. The liposomal preparation is preferred in patients that might be at risk of nephrotoxicity, although all preparations of amphotericin B have risk of nephrotoxicity. Individuals taking amphotericin B are monitored for renal function.

Treatment with itraconazole will need to continue for at least a year in severe cases, while in acute pulmonary histoplasmosis, 6 to 12 weeks treatment is sufficient. Alternatives to itraconazole are posaconazole, voriconazole, and fluconazole. Individuals taking itraconazole are monitored for hepatic function.

Therapy for cutaneous tuberculosis is the same as for systemic tuberculosis, and usually consists of a 4-drug regimen, i.e., isoniazid, rifampin, pyrazinamide, and ethambutol or streptomycin.

CLM can be treated in a number of different ways:

- Systemic (oral) agents include albendazole (trade name "Albenza") and ivermectin (trade name "Stromectol")).

- Another agent which can be applied either topically "or" taken by mouth is thiabendazole (trade name "Mintezol")), an anti-helminthic.

- Topical freezing agents, such as ethylene chloride or liquid nitrogen, applied locally can freeze and kill the larvae, but this method has a high failure rate because the larvae are usually located away from the site of the visible skin trails. Additionally, this is a painful method which can cause blistering and/or ulceration of the skin and it is therefore not recommended.

- It is recommended to use Benadryl or some anti-itch cream (i.e. Cortizone or Calamine lotion). This will help relieve some of the itch.

- Wearing shoes in areas where these parasites are known to be endemic offers protection from infection. In general, avoiding exposure of skin to contaminated soil or sand offers the best protection. In some areas dogs have been banned from beaches in an attempt to control human infection.

Mortality rate in treated cases

- 0-2% in treated cases among immunocompetent patients

- 29% in immunocompromised patients

- 40% in the subgroup of patients with AIDS

- 68% in patients presenting as acute respiratory distress syndrome (ARDS)

The best treatment for cutaneous leishmaniasis is not known. Treatments that work for one species of leishmania may not work for another; it is recommended that advice of a tropical medicine or geographical medicine specialist be sought. Ideally, every effort should be made to establish the species of leishmania by molecular techniques (PCR) prior to starting treatment. In the setting of a developing country, there is often only one species present in a particular locality, so it is usually unnecessary to speciate every infection. Unfortunately, leishmaniasis is an orphan disease in developed nations, and almost all the current treatment options are toxic with significant side effects. The most sound treatment for cutaneous leishmaniasis thus far is prevention.

- "Leishmania major" :"L. major" infections are usually considered to heal spontaneously and do not require treatment, but there have been several reports of severe cases caused by "L. major" in Afghanistan. In Saudi Arabia, a six-week course of oral fluconazole 200 mg daily has been reported to speed up healing. In a randomized clinical trial from Iran, fluconazole 400 mg daily was shown to be significantly more effective than fluconazole 200 mg daily in the treatment of cutaneous leishmaniasis.

- "Leishmania braziliensis" :Treatment with pentavalent antimonials or amphotericin is necessary, because of the risk of developing disfiguring mucocutaneous lesions.

- "Leishmania infantum" :"L. infantum" causes cutaneous leishmaniasis in southern France.

New treatment options are arising from the new oral drug miltefosine (Impavido) which has shown in several clinical trials to be very efficient and safe in visceral and cutaneous leishmaniasis. Recent studies from Bolivia show a high cure rate for mucocutaneous leishmaniasis. Comparative studies against pentavalent antimonials in Iran and Pakistan are also beginning to show a high cure rate for "L. major" and "L. tropica". It is registered in many countries of Latin America, as well in Germany. In October 2006 it received orphan drug status from the US Food and Drug administration. The drug is generally better tolerated than other drugs. Main side effects are gastrointestinal disturbances in the 1–2 days of treatment which does not affect the efficacy.

Secondary bacterial infection (especially with "Staphylococcus aureus") is common and may require antibiotics. Clinicians who are unfamiliar with cutaneous leishmaniasis may mistake the lesion for a pure bacterial infection (especially after isolation of "S. aureus" from bacterial skin swabs) and fail to consider the possibility of leishmaniasis.

Treatment is primarily symptomatic involving wound management of skin lesions and aggressive supportive therapy when renal compromise occurs. Some UK dogs with Alabama rot have been successfully treated since 2013. A webinar on Alabama rot by the Royal Veterinary College on 11 February 2015 was tutored by David Walker of Anderson Moores Veterinary Specialists.

Lesions in dolphins occur on the dorsal fin, head, , and peduncle. In January 2006, a potential epidemic of lobomycosis was reported in dolphins of the Indian River Lagoon in Florida.

Paracoccidioidomycosis (PCM) (also known as "Brazilian blastomycosis," "South American blastomycosis,","Lutz-Splendore-de Almeida disease" and "paracoccidioidal granuloma") is a fungal infection caused by the fungus "Paracoccidioides brasiliensis". Sometimes called "South American blastomycosis", paracoccidioidomycosis is caused by a different fungus than that which causes blastomycosis.

Fungal meningitis is treated with long courses of high dose antifungal medications. The duration of treatment is dependent upon the causal pathogen and the patient's ability to stave off the infection; for patients with a weaker immune system or diabetes, treatment will often take longer.

Treatment consists of antibiotics, elevation of the affected limb, and compression. For persons with elephantiasis nostras who are overweight or obese, weight loss is recommended. Oral retinoids have been used to treat the cutaneous manifestations of the disease.

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.

It is not practical to test or decontaminate most sites that may be contaminated with "H. capsulatum", but the following sources list environments where histoplasmosis is common, and precautions to reduce a person's risk of exposure, in the three parts of the world where the disease is prevalent. Precautions common to all geographical locations would be to avoid accumulations of bird or bat droppings.

The US National Institute for Occupational Safety and Health (NIOSH) provides information on work practices and personal protective equipment that may reduce the risk of infection. This document is available in English and Spanish.

Authors at the University of Nigeria have published a review which includes information on locations in which histoplasmosis has been found in Africa (in chicken runs, bats and the caves bats infest, and in soil), and a thorough reference list including English, French, and Spanish language references.

There is no cure for lichen planus, and so treatment of cutaneous and oral lichen planus is for symptomatic relief or due to cosmetic concerns. When medical treatment is pursued, first-line treatment typically involves corticosteroids, and removal of any triggers. Without treatment, most lesions will spontaneously resolve within 6–9 months for cutaneous lesions, and longer for mucosal lesions.

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.

The treatment is determined by where the disease is acquired, the species of "Leishmania", and the type of infection.

For visceral leishmaniasis in India, South America, and the Mediterranean, liposomal amphotericin B is the recommended treatment and is often used as a single dose. Rates of cure with a single dose of amphotericin have been reported as 95%. In India, almost all infections are resistant to pentavalent antimonials. In Africa, a combination of pentavalent antimonials and paromomycin is recommended. These, however, can have significant side effects. Miltefosine, an oral medication, is effective against both visceral and cutaneous leishmaniasis. Side effects are generally mild, though it can cause birth defects if taken within 3 months of getting pregnant. It does not appear to work for "L. major" or "L. braziliensis".

The evidence around the treatment of cutaneous leishmaniasis is poor. A number of topical treatments may be used for cutaneous leishmaniasis. Which treatments are effective depends on the strain, with topical paromomycin effective for "L. major", "L. tropica", "L. mexicana", "L. panamensis", and "L. braziliensis". Pentamidine is effective for "L. guyanensis". Oral fluconazole or itraconazole appears effective in "L. major" and "L. tropica".

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.

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 should be directed towards the specific underlying cause of the vasculitis. If no underlying cause is found and the vasculitis is truly limited to the skin then treatment is primarily supportive. Such treatment involves measures such as leg elevation, stockings, and topical steroids to relieve itching/burning. If the vasculitis does not self-resolve within 3–4 weeks, more aggressive treatment may be warranted. Oral colchicine or dapsone are often used for this purpose. If rapid control of symptoms is needed, a short course of high-dose oral steroids may be given. Immunosuppressive agents such as methotrexate and azathioprine may be used in truly refractory cases not responsive to colchicine or dapsone.

Tuberculosis verrucosa cutis (also known as "lupus verrucosus", "prosector's wart", and "warty tuberculosis") is a rash of small, red papular nodules in the skin that may appear 2–4 weeks after inoculation by "Mycobacterium tuberculosis" in a previously infected and immunocompetent individual.

It is so called because it was a common occupational disease of prosectors, the preparers of dissections and autopsies. Reinfection by tuberculosis via the skin, therefore, can result from accidental exposure to human tuberculous tissue in physicians, pathologists and laboratory workers; or to tissues of other infected animals, in veterinarians, butchers, etc. Other names given to this form of skin tuberculosis are anatomist's wart and verruca necrogenica (literally, generated by corpses).

TVC is one of the many forms of cutaneous tuberculosis, such as the tuberculous chancre (which results from the inoculation in people without immunity), and the reactivation cutaneous tuberculosis (the most common form, which appears in previously infected patients). Other forms of cutaneous tuberculosis are: lupus vulgaris, scrofuloderma, lichen scrofulosorum, erythema induratum and the papulonecrotic tuberculid.

It was described by René Laennec in 1826.

Cutaneous amoebiasis refers to a form of amoebiasis that presents primarily in the skin.

It can be caused by "Acanthamoeba" or "Entamoeba histolytica". When associated with "Acanthamoeba", it is also known as "cutaneous acanthamoebiasis".

It is also known as "amoebiasis cutis".

"Balamuthia mandrillaris" can cause cutaneous amoebiasis, but can prove fatal if the amoeba enters the bloodstream

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

Mucocutaneous leishmaniasis is an especially disturbing form of cutaneous leishmaniasis, because it produces destructive and disfiguring lesions of the face. It is most often caused by "Leishmania braziliensis", but cases caused by "L. aethiopica" have also been described.

Mucocutaneous leishmaniasis is very difficult to treat. Treatment involves the use of pentavalent antimonial compounds, which are highly toxic (common side effects include thrombophlebitis, pancreatitis, cardiotoxicity and hepatotoxicity) and not very effective. For example, in one study, despite treatment with high doses of sodium stibogluconate for 28 days, only 30% of patients remained disease-free at 12 months follow-up. Even in those patients who achieve an apparent cure, as many as 19% will relapse. Several drug combinations with immunomodulators have been tested, for example, a combination of pentoxifylline (inhibitor of TNF-α) and a pentavalent antimonial at a high dose for 30 days in a small-scale (23 patients) randomised placebo-controlled study from Brazil achieved cure rates of 90% and reduced time to cure, a result that should be interpreted cautiously in light of inherent limitations of small-scale studies. In an earlier small-scale (12 patients) study, addition of imiquimod showed promising results which need yet to be confirmed in larger trials.
