What is Cutaneous Leishmaniasis?
Cutaneous leishmaniasis is a skin infection caused by Leishmania parasites, which are transmitted through the bite of infected female sandflies. The disease primarily affects the skin, causing sores that may heal with scarring if left untreated. Early diagnosis and treatment help reduce complications and improve cosmetic outcomes.
Common Symptoms
* Painless or mildly painful skin sores
* Red bumps that gradually enlarge
* Ulcers with raised edges and a central crust
* Single or multiple skin lesions
* Lesions commonly occur on exposed areas such as the face, arms, hands, and legs
* Healing may leave permanent scars
Who Is at Risk?
* People living in or traveling to endemic areas
* Individuals exposed to sandflies during outdoor activities
* Military personnel, farmers, and outdoor workers
* People living in rural or forested regions
Diagnosis
A dermatologist diagnoses cutaneous leishmaniasis through a clinical examination and may confirm the diagnosis with laboratory tests such as skin smear, biopsy, microscopy, culture, or molecular tests (PCR).
Prevention
* Use insect repellents on exposed skin.
* Wear long-sleeved clothing, especially from dusk to dawn.
* Sleep under insecticide-treated bed nets in endemic areas.
* Reduce exposure to sandflies by avoiding high-risk areas when possible.
When to See a Dermatologist
Consult a dermatologist if you develop a persistent skin sore or ulcer that does not heal, especially after living in or traveling to an area where leishmaniasis is common. Early diagnosis and treatment can reduce the risk of scarring and complications.
Note: Cutaneous leishmaniasis is a treatable condition. Prompt medical evaluation and appropriate therapy are important for the best cosmetic and clinical outcomes.
