Cutaneous leishmaniasis is the most common form of leishmaniasis affecting humans. [4] It is a skin infection caused by a single-celled parasite that is transmitted by the bite of a phlebotomine sand fly .
Cutaneous leishmaniasis is the most common form, which causes an open sore at each bite site, which heals in a few months to a year and a half, leaving an unpleasant-looking scar. [2] [3] Diffuse cutaneous leishmaniasis produces widespread skin lesions which resemble leprosy, and may not heal on their own. [3]

[2] [3] [4] They are spread by sandflies of the genus Phlebotomus in the Old World, and of the genus Lutzomyia in the New World.
L. tropica causes a broad spectrum of leishmaniasis forms in humans. Most common is a variant called dry-type cutaneous leishmaniasis. After an incubation period lasting more than 2 months, a small brownish nodular lesion will appear with a slowly extending plaque reaching a size of 1–2 centimetres (0.39–0.79 in) after 6 months.

For this species, it has been known to cause cutaneous leishmaniasis and mucocutaneous leishmaniasis. Cutaneous leishmaniasis is commonly characterized with skin lesions, which can appear localized, or throughout the body. While mucocutaneous leishmaniasis is characterized with ulcers around the skin, mouth, and nose. This form of Leishmaniasis ...
The diffuse cutaneous type begins when the amastigote diffuses through the skin and metastasize to other tissue. This type does not produce ulcers and there is no treatment. Treatment of Leishmaniasis caused by L. mexicana consists of pentavalent antimonials as Pentostam or Glucantime injected direct into the ulcer or Intramuscular.
Leishmania infantum is the causative agent of infantile visceral leishmaniasis in the Mediterranean region [1] and in Latin America, where it has been called Leishmania chagasi. [2] [3] It is also an unusual cause of cutaneous leishmaniasis, [4] which is normally caused by specific lineages (or
