Folliculitis caused by Pseudomonas aeruginosa is a rare, adverse effect of the therapeutic or recreational use of hot tubs, whirlpools, and occasionally swimming pools. The condition is characterized by painful, papulopustular skin lesions often accompanied by low-grade fever, malaise, and other systemic symptoms. Prompt recognition and treatment may shorten the duration of the disease and, more importantly, prevent further cases by identifying the source of exposure.
