Cutaneous anthrax is a skin infection caused by Bacillus anthracis, which often begins as a pruritic papule. This characteristic feature is critical in the initial identification of the disease. Following the appearance of the papule, the lesion typically progresses to form a vesicle and eventually develops into a painless ulceration covered by a characteristic black eschar (necrotic tissue).

The progression from the pruritic papule to the ulcer with eschar formation is a hallmark of cutaneous anthrax, distinguishing it from other skin infections. Early recognition of the pruritic papule is important for timely treatment, which can significantly improve outcomes.

Other aspects, such as the assertion that cutaneous anthrax occurs specifically on the legs and feet or that it leads to vesicle formation without forming an eschar, are not representative of the disease’s typical presentation. Additionally, while cutaneous anthrax can lead to serious complications if untreated, it is not always fatal; most cases can be effectively treated with appropriate antibiotics, emphasizing the importance of early diagnosis and intervention.
