The primary morphological characteristics of pseudomonas folliculitis include papules, pustules, urticarial plaques, macules, and vesicles. In most cases, folliculitis caused by Pseudomonas aeruginosa will resolve spontaneously within 10 days. In severe cases, an oral antipseudomonal antibiotic, such as a fluoroquinolone, may be prescribed. In the case described here, the doc- tor and patient decided together to allow the folliculitis to resolve on its own. The patient did not want to use an antibiotic unless it was absolutely necessary.
Prevention requires meticulous cleaning of the hot tub and appropriate water chemical management.
The patient called the doctor a week later to report that the rash had disappeared, but some residual discoloration still remained. The doctor reassured her that the residual discoloration, which is due to postinflammatory hyperpigmentation, should fade during the coming months.
