Paraneoplastic pemphigus associated with rapidly progressing endophthalmitis caused by Morganella Morganii: A case report

Introduction: The ocular presentation of paraneoplastic pemphigus (PNP) has rarely been reported in the literature. In this report, we describe a 61-year-old male presenting with eruptive skin lesions associated with underlying non-Hodgkin's lymphoma who had rapid progressive corneal perforation with secondary endophthalmitis in the setting of PNP. Case description: A 61-year-old male presented to the emergency department complaining of skin eruption mimicking Stevens-Johnson syndrome, which was later found to be related to PNP. Initially, the patient complained of progressive ocular surface dryness in both eyes. Meanwhile, he developed mild pain in the right eye associated with blurry vision in both eyes and was managed with lubricants and topical antibiotics. A few days later, he was found to have corneal perforation with features suggestive of left endophthalmitis with possible early panophthalmitis. Intravenous antibiotic was administered, and primary evisceration of the left globe was performed. Histopathology revealed acute necrotizing keratitis and endophthalmitis. Vitreous analysis showed numerous gram-negative bacilli and a positive culture of Morganella morganii. The patient continued to be managed with frequent lubrications and punctual plugs in the fellow eye during the follow-up period. Conclusion: We describe the first case of endophthalmitis developing secondary to PNP-induced corneal melting and perforation. Anticipating unusual infectious sequelae in the setting of PNP might be warranted to actively detect and successfully manage dry eye disease before devastating complications develop.
