Cutaneous leishmaniasis
leishmaniasis that involves skin infection caused by Leishmania species, resulting in one or more cutaneous lesions
Cutaneous leishmaniasis is the most common form of leishmaniasis affecting humans. It is a skin infection caused by a single-celled parasite that is transmitted by the bite of a phlebotomine sand fly. About 30 species of Leishmania may cause cutaneous leishmaniasis. This disease is considered to be a zoonosis (an infectious disease that is naturally transmissible from animals to humans), with the exception of Leishmania tropica, which is often an anthroponotic disease (an infectious disease that is naturally transmissible from humans to vertebrate animals).
Signs and symptoms
Post kala-azar dermal leishmaniasis
Post-kala-azar dermal leishmaniasis (PKDL) is a recurrence of kala-azar that may appear on the skin of affected individuals months and up to 20 years after being partially treated, untreated, or even in those considered adequately treated. In Sudan, they can be demonstrated in up to 60% of treated cases. They manifest as hypopigmented skin lesions (such as macules, papules, or nodules), or facial redness. Though any organism causing kala-azar can lead to PKDL, it is commonly associated with L. donovani. which gives different disease patterns in India and Sudan. In the Indian variant, nodules enlarge with time and form plaques, but rarely ulcerate, while nodules from the African variety often ulcerate as they progress.
This brief starts where responsible research should: with the source description of “Cutaneous leishmaniasis” as leishmaniasis that involves skin infection caused by Leishmania species, resulting in one or more cutaneous lesions. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as leishmaniasis that involves skin infection caused by Leishmania species, resulting in one or more cutaneous lesions. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q2590966. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
