Abstract:
An Itching Pleasure Abstract. A 50-year-old female patient presents in the emergency department with an itchy, acneiform exanthema on the trunk and malaise for two days. Laboratory testing showed no abnormalities. After further questioning, the patient reported frequent use of her new whirlpool. Based on the medical history and the clinic we suspected a pseudomonas folliculitis. A bacterial culture of the pustules showed growth of Pseudomonas aeruginosa, which confirmed the diagnosis. Systemic antibiotics were not necessary in the absence of risk factors for severe progress or immunosuppression. The exanthema healed within a few days without any complications by using external disinfectants.
