Summary
A rare oncocytoma of the maxillary sinus was diagnosed in a 73-year-old female. This case represents the first reported instance of this extremely rare tumor in Nepal, highlighting its unusual occurrence.
Area of Science:
- Oncology
- Pathology
- Otorhinolaryngology
Background:
- Oncocytomas are benign epithelial tumors characterized by abundant granular eosinophilic cytoplasm due to mitochondrial accumulation.
- Maxillary sinus tumors are relatively uncommon, with oncocytomas being an exceptionally rare subtype within this location.
Observation:
- A case report of a 73-year-old female presenting with an oncocytoma of the maxillary sinus.
- The tumor's presence in the maxillary sinus is noted as an extremely rare occurrence.
Findings:
- This case is the first documented instance of maxillary sinus oncocytoma in Nepal.
- A review of existing literature identified only four previously reported cases of oncocytoma originating from the maxillary sinus worldwide.
Implications:
- This report expands the understanding of the geographic and clinical distribution of oncocytomas.
- Highlights the importance of considering rare diagnoses in head and neck oncology.
- Contributes to the limited global case data for maxillary sinus oncocytomas, aiding future research and clinical awareness.
