Introduction:
Tumors developed in a salivary ectasia of the parotid gland are very rare. The authors describe a case of oncocytoma developed in such an ectopy.
Observation:
The tumor located in the parotid region was observed in a 79-year old man. There was no facial palsy, no pain, and no cervical adenopathy. MRI was the most helpful to localize and characterize the tumor. Surgical resection was performed after a parotidectomy. Histology confirmed the diagnosis.
Discussion:
The physiopathology of this rare entity is discussed with a literature review. It might correspond to a mitochondrial anomaly.
