Summary
Cutaneous larva migrans, a tropical skin infection, can manifest months after travel. Hookworm larvae may remain dormant before causing symptoms, delaying diagnosis.
Area of Science:
- Dermatology
- Infectious Diseases
- Parasitology
Background:
- Cutaneous larva migrans (CLM) is a skin disease caused by hookworm larvae.
- It is prevalent in tropical and subtropical regions worldwide.
- Diagnosis typically relies on a history of recent tropical travel.
Observation:
- This case report details a patient with CLM whose symptoms emerged five months post-travel to Tanzania.
- This presentation is atypical, as CLM symptoms often appear sooner after exposure.
Findings:
- Hookworm larvae responsible for CLM can remain dormant in the skin for extended periods.
- Delayed presentation of CLM is possible, occurring significantly after the initial exposure during travel.
Implications:
- Clinicians should consider CLM even with a remote travel history.
- The possibility of larval dormancy necessitates a broader differential diagnosis for pruritic skin lesions in returning travelers.

01:30Leishmaniasis
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...
01:22American 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...
