Another summertime condition

What's your diagnosis? A. Scabies B. Foreign body C. Cercarial dermatitis D. Hookworm disease CASE DISCUSSION This is a classic case of cutaneous larva migrans (CLM), representing the invasion and migration within the skin of the hookworm larva (choice D). While the patient presented may have spent a week on the beaches of a foreign tropical resort, the classic, serpiginous appearance of the lesion on the sole of his foot is virtually diagnostic and should not be confused with swimmer's itch.
