A Massive Posterior Neck Mass : Lipoma or Something More Sinister?

الملخص EN

Lipomas are slow-growing benign soft-tissue tumors which are typically asymptomatic and occur in approximately 1% of the population.

A lipoma is considered to be of excessive size when it is greater than 10 cm in length (in any dimension) or weighs over 1000 g (Kransdorf (1995)).

We describe a case of a man presenting with a giant posterior neck mass which greatly reduced the sagittal range of cervical spine.

A discussion of the pathophysiology of lipomas and a literature review regarding giant lipomas versus malignancy follows.
