Dercumâs disease, also known as adiposis dolorosa, is a rare disorder characterized by multiple, painful growths consisting of fatty tissue, called lipomas. They mainly occur on the trunk, the upper arms and upper legs and are found just below the skin.
Most people with FRDA are diagnosed before age 25, but approximately 25% have an âatypicalâ presentation whereby the disease onset occurs after the age of 25. LOFA and VLOFA are subtypes that affect approximately 15% of individuals with Friedreichâs ataxia. For LOFA the age of onset is between the ages of 26 and 39 years, and for VLOFA the age of onset is after the age of 40 years.
