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.
