title: Dercum's disease (adiposis dolorosa): a new case-report.
abstract: Dercum's disease, or adiposa dolorosa, is a rare condition characterized by the development of multiple painful subcutaneous lipomas. Postmenopausal women are selectively affected. The ankle area is an uncommon site of involvement. We report a case with lipomas about the ankle, and we review the relevant literature.
  
  
  METHODS
  This 46-year-old perimenopausal woman receiving follow-up for depression presented in December 1997 for swelling and mechanical pain in the right ankle. Lumps behind and under the malleoli were removed surgically and found to have the typical histological features of lipomas. In January 2000, a lump developed behind and under the malleoli of the left ankle, and the lumps on the right recurred. The physical examination showed obesity, with a body mass index of 32.04 kg/m(2). Firm, mobile, painless lumps were felt under and behind the malleoli on both sides. The ankles were painful, although range of motion was normal. Examination of the back found two similar lumps. The erythrocyte sedimentation rate was 10 mm/h and the C-reactive protein level was 6 mg/l. Serum lipid levels were normal. Findings were normal from plain radiographs of the ankles. Ultrasound scanning of the ankles confirmed that the lumps were composed of adipose tissue. Magnetic resonance imaging visualized an arc-shaped lipomatous mass on the left. Whole-body bone density measurement found an increase in fat mass of the lower limbs with normal bone mass. The ankle lipomas were removed surgically. At last follow-up 18 months later, she was free of recurrence.
  
  
  CONCLUSIONS
  Dercum's disease is a rare condition of unknown etiology characterized by multiple, often painful lipomas. Paresthesia in the overlying skin is common. Lipomas about the joints cause mechanical arthralgia. The diagnosis, which is often delayed, rests on ultrasonography and, above all, magnetic resonance imaging. A combination of medications, surgery, and psychiatric care is usually needed. The treatment aims at relieving the pain and restoring a normal appearance.
