A 40-year-old male, upon returning from a beach holiday, noticed a serpiginous, intensely pruritic linear lesion over the dorsum of foot which moved slowly across the skin to reach up to his toes in 5-6 days. The most likely clinical diagnosis is:
Cutaneous larva migrans
Cutaneous larva migrans, caused by animal hookworm larvae (e.g., Ancylostoma braziliense) penetrating skin exposed to contaminated sand (typical of beach exposure), produces a slowly migrating serpiginous, intensely pruritic linear track, classically over the feet.
