case_images: A flare reaction occurred at the levofloxacin injection site 15 min after the test was administered and disappeared 6 h later (Fig. 1A, B). However, surprisingly, an indurative erythema with warmth at the ethambutol injection site emerged 6 h after the skin test, peaked at 24 h (Fig. 1A, B), and resolved on day 7.
