Oncocytoma of the salivary glands
Oncocytomas of the salivary glands are rare benign epithelial tumors.
They typically present in older individuals (6th to 8th decades of life). There may be a slight increased female predilection.
While they can affect any of salivary glands. They most commonly in the parotid gland (around 80% of cases).
Often seen as a well-defined parotid mass showing homogeneous enhancement.
Treatment and prognosis
There are benign lesions and are often surgically excised. They have a recurrence rate of around 20-30% (especially with incomplete excision or multinodularity). Malignant differentiation and metastasis are extremely rare.
History and etymology
It was first described by Jaffe in 1932.
