Cutaneous anthrax in an unusual location: case report

Cutaneous anthrax is well known, unlike anthrax of the lumbar region, which is not reported elsewhere. We present a case of anthrax of the lumbar region in a 50-year-old man. The infection was characterised by a wide, black eschar and oedema on an erythematous ground. After isolation of the Gram-positive bacilli from the skin lesions, prompt antibiotic treatment (intravenous sulbactam-ampicillin 1.5 g every six hours) was initiated. Following eradication of the bacilli after 14 days of antibiotic treatment, a split-thickness skin graft was applied. A diagnosis of anthrax depends on clinical suspicion. Early diagnosis, antibiotic and surgical treatment can facilitate the treatment and prevent development of complications.
