Area of Science:

  • Infectious Diseases
  • Parasitology
  • Dermatology

Context:

  • American cutaneous leishmaniasis is endemic in Latin America.
  • Caused by Leishmania species like L. (V.) braziliensis, L. (L.) mexicana, and L. (V.) panamensis.
  • Reservoirs include forest rodents, and vectors are Lutzomyia sandflies.

Purpose:

  • To describe the epidemiology, clinical manifestations, diagnosis, and treatment of American cutaneous leishmaniasis.
  • To highlight the spectrum of disease, from localized ulcers to diffuse and mucosal forms.
  • To discuss diagnostic methods and current therapeutic options.

Summary:

  • The disease spectrum includes localized cutaneous ulcers, diffuse cutaneous leishmaniasis, and mucosal disease.
  • Diagnosis relies on identifying amastigotes in tissue or promastigotes in culture.
