Abstract
Oncocytic lipoadenomas are a rare sub-category of fat-containing tumors of the salivary glands. These tumors are characterized by their oncocyte-predominant epithelial component admixed with mature adipocytes. This condition has been rarely reported to affect the parotid and the submandibular glands. We report a case of a 69-year-old male who presented to our otolaryngology outpatient department with a complaint of a gradually growing right-sided infra-auricular neck mass. A surgical full mass excision was performed, and a histopathological evaluation yielded a tumor with oncocytes organized in tubular structures. This paper presents the fourth unusual case of a giant oncocytic lipoadenoma of the parotid gland measuring 11.5 × 10.5 × 11.5 cm in anteroposterior, transverse, and cranial planes, respectively.
