Hot tub folliculitis: a clinical syndrome.

With the increasing use of hot tubs, patients are being seen with a distinct clinical syndrome that appears several hours or days after hot tub exposure. It consists of a maculovesicular, often pruritic rash, and commonly occurring associated symptoms including fever, upper respiratory tract complaints, axillary adenopathy and breast tenderness. Cultures in the cases described here grew out Pseudomonas aeruginosa, giving a diagnosis of Pseudomonas folliculitis. The illness clears spontaneously without any treatment. Proper attention to hot tub chlorination and use are probably important in preventing this problem, and awareness of the syndrome by physicians may prevent unnecessary and costly diagnostic studies and treatment programs.
