title: Orbital squamous cell carcinoma following retinal detachment surgery.
abstract: BACKGROUND
  Orbital squamous cell carcinoma following retinal detachment surgery is a rare condition. A proposed pathogenesis involves implantation of conjunctival squamous epithelium at the time of surgery, with subsequent malignant transformation.
  
  
  RESULTS
  An 81-year-old Caucasian man presented with a six-month history of a discharging painful red right eye. Ten years earlier a right scleral buckling with an encircling sponge exoplant had been performed. Examination revealed exposure of the sponge, and a large mass in the superomedial conjunctival fornix. Computed tomography revealed a mass invading around the globe in the region of the exoplant. Biopsy revealed squamous cell carcinoma. Orbital exenteration was performed.
  
  
  CONCLUSIONS
  Orbital squamous cell carcinoma may arise following retinal detachment surgery presumably due to iatrogenic conjunctival implantation deep in the orbit.
