Necrotic Herpes Simplex Virus Infection of the Nose and Orbit

This is the first reported case of necrotizing nasal and sinus herpes infection with orbital involvement. A 94-year-old male with a past medical history of hypertension, congestive heart failure, and chronic kidney disease presented with necrotic nasal cellulitis and a red left eye with blurry vision. Onset was 2 weeks prior with an upper lip fever blister. He was admitted to medicine and started on antimicrobials. Maxillofacial computed tomography scan revealed pansinusitis with involvement of bilateral medial orbital walls. Initial nasal biopsy was negative. Repeat biopsy was positive for herpes simplex virus 1. His nose was debrided with full-thickness skin grafting. While there are reports of necrotizing herpes simplex, none were to the extent of our patient nor raised suspicion for invasive fungal sinusitis. Differentiating is important as this patient made a full recovery in comparison to patients with mucormycosis where mortality is often as high as 80%.
