Summary
Recurrent ameloblastoma, a rare jaw tumor, can reappear in the temporal fossa decades after initial treatment. This case suggests implantation seeding via prior surgical wounds.
Area of Science:
- Oral and Maxillofacial Surgery
- Oncology
- Pathology
Background:
- Ameloblastoma is a benign but locally aggressive odontogenic tumor.
- Recurrence is common, but presentation in the temporal fossa is exceptionally rare.
Observation:
- A 45-year-old woman experienced a delayed recurrence of mandibular ameloblastoma.
- The tumor reappeared in the temporal fossa 10 years post-mandibular reconstruction.
Findings:
- This represents a rare instance of ameloblastoma recurrence in the temporal fossa.
- The temporal lesion is hypothesized to be an implantation metastasis from the mandibular site.
Implications:
- Highlights the potential for distant seeding of ameloblastoma through surgical interventions.
- Suggests meticulous surgical technique and follow-up are crucial for managing recurrent ameloblastoma.
