Cutaneous (non-HIV) infections.

Cutaneous infections continue to represent a large proportion of inpatient dermatology. Though most infectious skin diseases do not warrant hospitalization, some do and can rapidly become fatal if not treated promptly. A selected group of infections are reviewed--primary cutaneous infections, exotoxin-mediated syndromes, and systemic infections--that warrant hospitalization. Dermatologists play a critical role in the synthesis of patient history and appreciation of morphologic skin disease, which, when coupled with appropriate lab tests, may help to establish a diagnosis allowing for the timely implementation of effective and targeted therapy.
