Lipomatosis is a medical condition characterized by the growth of multiple fatty lumps beneath the skin. However, there are several synonyms for this condition that you might come across in medical literature or conversations with your doctor. Some of these synonyms include adiposis, liposis, lipohyperplasia, and adipose tissue hyperplasia. These terms all refer to the same basic condition, which is an excessive growth of fat cells in the body. Lipomatosis can occur in many different parts of the body, including the legs, arms, abdomen, and neck. While it is generally considered a benign condition, it can cause discomfort and cosmetic concerns in some individuals and may require treatment in severe cases.
