What is the difference between noninfiltrative and infiltrative lipomas?
Noninfiltrative lipomas are also known as simple lipomas. They are located beneath the skin and are quite easy to remove. Infiltrative lipomas in dogs on the other hand tend to grow into adjacent tissues. They invade fascia and muscle tissue to a greater degree than simple lipomas. They are therefore hard to remove and tend to regrow once removed.
