Multiple lipomas
Multiple fatty lumps
HP:0001012
What it means
The presence of multiple lipomas (a type of benign tissue made of fatty tissue).
A lipoma is a benign tumor composed of fatty tissue. They are the most common form of soft tissue tumor and are usually soft to the touch, movable, and generally painless (but there is a separate entity of painful multiple lipomas which is a hereditary disease called Dercum disease or adiposis dolorosa). Many lipomas are small (under one centimeter diameter) but can enlarge to sizes greater than six centimeters. Lipomas are commonly found in adults from 40 to 60 years of age, but can also be found in children.
