| Sumario: | Deployed military personnel are often faced with a variety of exposures unfamiliar to U.S. physicians. This is the first report to describe an outbreak of a pustular disease among U.S. personnel deployed to Pakistan in support of Operation Enduring Freedom. Up to 10% of the base population was afflicted with a pustular eruption and an accompanying halo of erythema. A retrospective chart review and ongoing patient care resulted in 191 cases. Various therapies were used, including "watchful waiting." Gradual resolution occurred with residual area(s) of hypo- or hyperpigmentation. An irritant contact dermatitis was suspected based upon clinical presentation; staphylinid (rove) beetles were implicated. Rove beetle dermatitis from a pederin toxin has occurred in other parts of the world but has not been previously reported in Pakistan. We discuss the nature and progression of the dermatitis, treatments, outcomes, measures to control exposures, and the implications of such outbreaks.
