Full Answer

Intramuscular lipomas occur deep in the muscle tissue, and they are difficult to diagnose properly. They are often confused with a sarcoma, which is a life-threatening malignant tumor. Doctors can perform a frozen biopsy on the growth to make sure that it is a lipoma and not a sarcoma, as Lipoma NET explains.

An existing lipoma cannot spread, and it is not deadly. Lipomas occur most frequently in adults between the ages of 40 and 60, according to Healthline.

The cause of intramuscular lipomas is not clear as of 2015. There are a few theories that link the appearance of intramuscular lipomas to metaplasia, trauma, chronic irritation and congenital development, as reported by Lipoma NET.

Unfortunately, intramuscular lipomas can reappear after surgery, and the recurrence rate can be as high as 80 percent. Additionally, self care cannot reduce a lipoma. Ice and heat packs effectively treat other skin lumps, but they are ineffective on lipomas because they are fat-based tumors. Patients should consult their doctors to determine the best form of treatment for their lipomas, as Healthline recommends.
