Oncocytic features in salivary duct carcinoma, a potential pitfall for misdiagnosis as Warthin tumor in fine needle aspiration specimens: A cytomorphologic analysis of 14 cases.

Precise diagnosis of SDC based on cytomorphologic features alone can be challenging. Oncocytic change is one of the most consistent features observed in this case series and when associated with less pronounced cytologic atypia, can potentially lead to misdiagnosis as Warthin tumor. SDC should be considered in the differential diagnosis of oncocytic salivary gland neoplasms where precise diagnosis is not possible.
