Hibernoma of the neck: a case report.
J Postgrad Med Inst Jan ;27(2):220-2.

Hibernoma denotes a tumor derived from brown fat. It is an uncommon tumor that has been described only in a few case reports and small series. Although it is usually found in the interscapular region, it has also been reported in sites where brown fat is less common. Only a few cases have been described in the neck region. We report a case of 47 years old man who was admitted with history of a mass in his posterior cervical region. Upon surgical excision, a soft encapsulated mass was found which pathologically was consistent with hibernoma.
