RESUMEN
Eyelid necrosis is a very rare disease, usually secondary to trauma or infections. Pseudomonas aeruginosa [PA] eyelid necrosis remains principally a clinical diagnosis and it is often missed early in its presentation because of the difficulty in differentiating it from more common soft tissue infections. However, when the diagnosis is made we must act quickly due to the fatal evolution if not handled properly. We present the case of a non-neutropenic 53-year-old male patient with a history of alcoholism, smoking habit and lung cancer under chemotherapy treatment who developed ocular necrotizing fasciitis due to PA with perforation of his left eye and severe bilateral sclera ischemia despite intensive antibiotic treatment and surgical debridement.
