Hot tub-associated dermatitis due to Pseudomonas aeruginosa. Case report and review of the literature.

A healthy, 27-year-old man had development of a maculopapular, pustular rash due to Pseudomonas aeruginosa, serotype 0:4, after bathing in a hot tub. Two persons sharing the same tub manifested a similar rash. In the first patient, the eruption was distributed mainly over the back, buttocks, and upper arms, appearing abruptly within 24 to 72 hours after use of the hot tub. Pruritus, malaise, and low-grade fever were the main associated features. The rash subsided spontaneously within ten days. This article reviews the literature on this form of cutaneous infection due to P aeruginosa.
