Olfactory neuroblastoma is a rare and often locally aggressive malignancy that invades the orbit via local destruction. It is known to recur in a delayed fashion, particularly to the neck lymph nodes. This is a case of a 65-year-old gentleman who presents with recurrence in the orbit and a neck lymph node 19 years after treatment for his initial disease. This report describes the longest known interval in orbital recurrence and should alert the monitoring physician that extreme delays in recurrence can occur.
