A case of cutaneous anthrax.

A 63-year-old man developed black crusts on the parietal scalp that showed mixed infections of dermatophytes and Bacillus anthracis on culture. The lesions improved with bifonazole, griseofulvin and bacampicillin hydrochloride. Although cutaneous anthrax is now a very rare disease, the mortality is high in untreated cases. If a patient has black crusts, anthrax should be differentiated firstly.
