Leishmaniasis01:30

Leishmaniasis

Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
American Trypanosomiasis01:22

American Trypanosomiasis

Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.

Area of Science:

  • Dermatology
  • Infectious Diseases
  • Parasitology

Background:

  • Cutaneous larva migrans (CLM) is a common parasitic skin infection often acquired in tropical and subtropical regions.
  • Diagnosis is typically based on characteristic clinical presentation: a pruritic, serpiginous, and advancing skin lesion.
  • Risk factors include activities like sunbathing or walking barefoot on contaminated beaches.

Purpose of the Study:

  • To present a case of CLM in a traveler returning from Brazil.
  • To review the epidemiology, clinical features, diagnosis, and treatment of CLM.

Main Methods:

  • Case report of a 32-year-old Mediterranean man with a 2-week history of pruritic cutaneous lesions.
  • Clinical examination revealed a characteristic serpiginous, erythematous, and advancing lesion.
  • Laboratory analysis showed elevated eosinophil count; treatment with oral albendazole was initiated.

Main Results:

  • The patient presented with a 7-cm long, 2-mm wide serpiginous lesion on his left knee.
  • Initial treatment with antihistamines and topical steroids was ineffective.
  • Albendazole (400 mg/d for 3 days) resulted in complete symptom resolution within one week.

Conclusions:

  • Cutaneous larva migrans is a frequent diagnosis among travelers returning from endemic areas.
  • Early diagnosis and appropriate antiparasitic treatment, such as albendazole, are crucial for effective management.
  • Understanding CLM epidemiology and clinical presentation aids in prompt diagnosis and treatment.
