[Intermuscular and intramuscular lipomas of the neck].

Two cases of deep lipomas of the neck developed between the skeletal muscles were presented: one intermuscular and the other intramuscular. Taking into consideration the rarity of the case, the authors examined the clinical surgical aspect, paying special attention to the relationship between sonographic and computerized tomographic characteristics and the histological aspects in order to define whether the lipomatous tumors were benign or malignant. They also studied the localization of cervical lipomas, of lipoblastomas of hibernomas and of liposarcomas and defined an anatomo-clinical classification of both superficial and deep cervical lipomas.
