Picture of Lipoma (2 of 2)

Familial lipoma syndrome, an autosomal dominant trait appearing in early adulthood, consists of hundreds of slowly growing nontender lesions. Adipositas dolorosa, or Dercum's disease, occurs in women in middle age; there are multiple tender, not circumscribed but rather diffuse fatty deposits. Benign symmetric lipomatosis, which affects middle-aged men, consists of many large nontender, coalescent poorly circumscribed lipomas, mostly on the trunk and upper extremities; they coalesce on the neck and may lead to a “horse-collar” appearance. Shown here are multiple lipomas on the lower arm in a 50-year-old male patient. In this patient lesions were symmetric and were also found on the trunk and lower extremities.
