Cellulitis Left Lower Leg Secondary to Pseudomonas aeruginosa Bacteremia: A Case Report

Cellulitis is a non-necrotizing inflammation of the skin and subcutaneous tissues that usually results from an acute infection. The gram-negative bacillus Pseudomonas aeruginosa causes a wide range of clinical illnesses. It is, however, most commonly linked to a hospital-acquired illness. We describe a case report of a 45-year-old Saudi man who developed vesiculous bullae, scaling, and sloughing of the overlying skin after initially experiencing redness and heat in the mid-right lower thigh. Though it was not a common suspect bacteria, Pseudomonas aeruginosa was detected from the case. It's possible that it's the result of a community-acquired infection.Patient was treated conservatively with intravenous antibiotics and local hygiene treatments such as Vaseline (bactigrass) dressing and topical antibiotics.Patient improved and discharged with complete resolution of cellulitis.

Review the laboratory tests used in the evaluation of community-acquired infections.
Summarize the management of community-acquired infections.
Outline the importance of improving care coordination among the interprofessional team to prevent transmission of infections and enhance the delivery of care for patients affected by community-acquired infections.
