Cutaneous Larva Migrans Statements Analysis
We need to evaluate the correctness of the given statements regarding Cutaneous Larva Migrans (CLM).
- Statement 1: Correct. Cutaneous Larva Migrans is indeed a common condition, especially among travelers returning from endemic areas, often presenting as characteristic linear or serpiginous skin lesions.
- Statement 2: Correct. Exposure to hookworm larvae, the causative agents of CLM (commonly species like Ancylostoma braziliense or Ancylostoma caninum), frequently occurs in tropical and subtropical regions through contact with contaminated soil or sand, such as on beaches.
- Statement 3: Incorrect. A hallmark symptom of Cutaneous Larva Migrans is intense itching (pruritus). The condition is characteristically pruritic, not non-pruritic.
- Statement 4: Correct. The larva migrates within the epidermal layer of the skin, creating a visible track. This migration typically progresses at a rate of about 2-3 cm per day, which is a defining clinical feature.
Conclusion
Based on the analysis, statements 1, 2, and 4 are correct, while statement 3 is incorrect. Therefore, the correct combination is 1, 2, and 4.
