Abstract
Corals are the marine organism that belongs to the phylum Cnidaria, and are one of the common causes of superficial injury in the marine environment. In addition to acute reactions such as burning or stinging pain and erythema, coral injuries may present with complications such as foreign body reactions, bacterial infections, and/or localized eczematous reactions. A 23-year-old male presented with an erythematous edematous tender patch with centrally grouped vesicles on the left ankle; the injury had occurred during skin-scuba diving 2 days before. A biopsy of the lesion treated with hematoxylin-eosin stain showed epidermal necrosis with subepidermal blisters and neutrophilic panniculitis. Herein we report a case of cellulitis caused by the nematocyst stings of corals.
