Periorbital Ecthyma Gangrenosum Due to Pseudomonas Aeruginosa Septicemia in an Infant with Sepsis: A Case Report

Purpose: This article aimed to report an infant case of congenital neutropenia (CN) with periorbital ecthyma gangrenosum (EG) due to pseudomonas aeruginosa septicemia.Case report: A previously healthy six-month-old male infant with fever, diarrhea, poor feeding, pancytopenia, periorbital swelling, and eyelid ulcers in the left eye was admitted in pediatric intensive care unit (PICU). He had positive blood and eyelid wound cultures for pseudomonas aeruginosa. He was treated with broad spectrum intravenous antipseudomonal antibiotics and debridement of periorbital lesions and discharged after ۱۸ days with a stable condition. Adequate hematologic workup for pancytopenia revealed the diagnosis of CN.Conclusion: There is a possibility that EG be developed in patients with immunodeficiency as preseptal cellulitis with isolated typical lesions, and this should be considered in the treatment.
