Introduction
Lipomatous tumors are one of the commonly seen tumors of subcutaneous soft tissue. However, those originating from the salivary gland are extremely rare. Oncocytic adenolipoma or lipoadenoma is one of the rare biphasic lipomatous tumors which is composed of oncocytes admixed with mature adipocytes.1 The first case of oncocytic adenolipoma of the submandibular gland was reported by Hirokawa et al. in 1998.2 Only the case reports are published in the literature due to its rarity. In the 2005 World Health Organization (WHO) histologic classification of tumors of salivary glands, this tumor was not included.3 We report a case of a patient with a huge painless mass in the neck with a history of more than 18 years of swelling and underwent excision. The case was followed up for 5 years post-surgery to rule out excision. The paper is presented to consider for this rare differential diagnosis for neck mass.
