creeping eruption; cutaneous larva migrans
Medical term for a skin condition caused by hookworm larvae, characterized by a winding, thread-like rash. The gloss 'ringworm' is a common but imprecise translation; the condition is distinct from dermatophyte infections.
In tropical regions, creeping eruption can be contracted from soil.
From 匐行 (crawling, creeping) + 疹 (eruption, rash). The term describes the characteristic creeping track of the larval migration.
