(bur'ro) (Anglosaxon. Burg - gallery)
A cuniculus, passage, or tunnel in the skin that houses a metazoal parasite, particularly the acarus of scabies.
Burrows in scabies can be widespread, but are typically seen in the finger webs, along the lateral aspect of the hand, and the volar wrist. There is often an associated erythema, and small papulopustules at one end of the burrow.
