Answer

Cutaneous anthrax results from skin exposure to Bacillus anthracis, a gram-positive bacillus. Cutaneous anthrax evolves from a pruritic papule to an ulcerated wound in 1 or 2 days and then into a black eschar over the next week or so. Associated regional lymphadenopathy may be present. Findings on special stains and cultures of the wound exudate are diagnostic.

Anthrax is transmissible from specimens; therefore, laboratory personnel should be warned in the event of clinical suspicion of this disease. Of course, appropriate public health authorities must be notified. See Anthrax for details.
