Lipomas are adipose tumors that are often located in the subcutaneous tissues of the head, neck, shoulders, and back. Lipomas have been identified in all age groups but usually first appear between 40 and 60 years of age. These slow-growing, nearly always benign, tumors usually present as nonpainful, round, mobile masses with a characteristic soft, doughy feel. Rarely, lipomas can be associated with syndromes such as hereditary multiple lipomatosis, adiposis dolorosa, Gardner’s syndrome, and Madelung’s disease. There are also variants such as angiolipomas, neomorphic lipomas, spindle cell lipomas, and adenolipomas. Most lipomas are best left alone, but rapidly growing or painful lipomas can be treated with a variety of procedures ranging from steroid injections to excision of the tumor. Lipomas must be distinguished from liposarcoma, which can have a similar appearance.
Lipomas are slow-growing, nearly always benign, adipose tumors that are most often found in the subcutaneous tissues. Most lipomas are asymptomatic, can be diagnosed with clinical examination and do not require treatment. These tumors may also be found in deeper tissues such as the intermuscular septa, the abdominal organs, the oral cavity, the internal auditory canal, the cerebellopontine angle and the thorax. Lipomas have been identified in all age groups but usually first appear between 40 and 60 years of age. Congenital lipomas have been observed in children.Some lipomas are believed to have developed following blunt trauma.
