Odontogenic Fibromyxoma in a Pediatric Patient: A Rare Aggressive Neoplasm With Recurrent and Fatal Outcome.

Odontogenic myxomas, a rare intraosseous neoplasm, usually present as a slow rate of bony expansion and are painless in nature, and eventually lead to facial deformity. The tumor is thought to arise from the mesenchyme of the tooth germ and is associated with an impacted tooth. The fact that this tumor is widely distributed throughout the jaws and facial bones suggests its odontogenic neoplasm origin. Furthermore, its histology is similar to that of the developing tooth's stellate reticulum. Fibromyxomas account for a small proportion of all myxomas. We herein report a complex case of recurrent odontogenic fibromyxoma that requires multiple surgical interventions and recurrences that lead to the death of the patient due to disease progression.
