Other Potentially Life-Threatening Conditions with Mucocutaneous Findings (Leptospirosis, Typhoid Fever, Dengue, Diphtheria, Murine Typhus)

There are several conditions with mucocutaneous findings that are potentially life-threatening, particularly in certain vulnerable populations. In this chapter, leptospirosis, typhoid fever, dengue, diphtheria, and murine typhus are reviewed. The disease time course of classic and atypical presentations is detailed to assist making the diagnosis in subtle cases. Associated symptoms are discussed as well as a comparison with disease mimics and differential diagnoses. Key diagnostic features are emphasized, and evidence-based management of each condition is detailed in this chapter.
