Diagnostic challenge of parotid multifocal adenomatous oncocytic hyperplasia: A case report

ABSTRACT

@#Parotid glands have diverse histological findings thanks to abundant different types of cells presence in the gland. Our routine fine needle aspiration cytology might be inaccurate and misleading in cases where there are cell changes due to ongoing concurrent infection and chronic sialadenitis, which might have mimicked tumoural changes. We highlighted a rare case of multiple florid benign hyperplasia of oncocytic cells of the parotid gland that manifest as parotid swelling. The characteristic multifocality of the lesion and high rate of recurrences, although not a known malignant entity, resulting in a significant shift in the treatment plan for the patient.
