When there is much fibrous tissue in the tumor it is much firmer, and is known as a fibro-lipoma.

Brander describes a young native of Manchuria, North China, from whom he removed a fibro-lipoma weighing 50 pounds.

The growth had progressively enlarged for eleven years, and at the time of extirpation hung as an enormous mass from beneath the left scapula.

In operating the tumor had to be swung on a beam.

The hemorrhage was slight and the patient was discharged in five days.
The true lipoma must be distinguished from diffuse accumulations of fat in different parts of the body in the same way that fibroma is distinguished from elephantiasis.
