An 81-year-old noticed progressive enlargement of veins over the neck, chest, and abdominal wall, yet feels completely well.
What's the most likely explanation for this striking finding?
Cutaneous Larva Migrans (CLM)
Clinical Overview
Presentation: Classic serpiginous, erythematous, intensely pruritic track moving across the dorsum of the foot ("creeping eruption").
Etiology: Caused by skin penetration and subcutaneous migration of animal hookworm larvae, most commonly Ancylostoma braziliense or Ancylostoma caninum (dog and cat hookworms).
Transmission: Acquired through direct skin contact with soil or sand contaminated with animal feces (e.g., walking barefoot on warm, moist beaches).
Pathophysiology: Human skin acts as an accidental host; larvae lack the collagenase required to penetrate the basement membrane into the deeper tissues or blood vessels, confining them to the epidermis where they migrate a few millimeters to centimeters per day before dying.
