The Diagnosis: Madelung Disease (Benign Symmetric Lipomatosis)

A 56-year-old man presented for evaluation of massive subcutaneous nodules the bilateral upper arms, shoulders, chest, abdomen, and lateral aspect of the proximal thighs (Figures 1 and 2) that developed over the last 12 to 18 months and continued to enlarge. In addition, he was beginning to develop symptoms of neuropathy of the bilateral hands. The patient had a long-standing history of alcohol abuse. Biopsies performed by the patient’s primary care physician revealed benign adipose tissue. He was referred to the dermatology clinic and subsequently diagnosed with Madelung disease.

Madelung disease, also known as benign symmetric lipomatosis and Launois-Bensaude syndrome, is characterized by multiple large masses of nonencapsulated adipose tissue. These masses are symmetric and most prominent on the head, neck, trunk, and proximal extremities. Classically, a pseudoathletic appearance is described. Madelung disease most frequently affects men aged 30 to 60 years. In more than 90% of cases, it is associated with alcoholism.

In general, the masses of adipose tissue are asymptomatic. However, airway compression and dysphagia requiring surgical intervention has been reported in the otolaryngology literature.¹ In addition, neuropathy develops in 84% of cases.² Nerve biopsies from patients with Madelung disease have revealed a pattern of axonopathy that is distinct from alcohol-induced neuropathy.³ This neuropathy can involve sensory and motor nerves, with the most prominent findings being muscle weakness, tendon areflexia, interosseous muscle atrophy, vibratory sensation loss, and hypoesthesia. Furthermore, dysfunction of the autonomic nervous system can lead to segmental hyperhidrosis, gustatory sweating, and abnormal autonomic cardiovascular reflexes.² Many patients who develop neuropathy will eventually become incapacitated.

The etiology of Madelung disease is not fully understood. There are several theories on the pathogenesis of this disease, most describing metabolic disturbances induced by alcohol. Specifically, studies have revealed chronic alcohol use causes numerous deletions in mitochondrial DNA.^4,5 The mitochondrial DNA damage may explain both the resistance of the lipomatous masses to lipolysis and the nerve-related changes. Comparisons between human immunodeficiency virus/highly active antiretroviral therapy–associated lipodystrophy and Madelung disease lend credence to the metabolic disturbance theory and may help clarify the specific mechanisms involved.⁶

There have been no cases of spontaneous resolution, even in patients who stop consuming alcohol. For this reason, most patients are referred to a surgeon. Many surgeons prefer open excision for debulking large lipomatous masses, but this technique typically requires general anesthesia. For those in whom this treatment is not an appropriate option, liposuction can be considered with tumescent anesthesia.⁷ A combination of these surgical modalities also is an option.

Madelung disease is a distinctive disorder typically affecting chronic alcoholics. Recognition of this clinical entity is important, as severe neuropathy and airway compromise may ensue. Although surgical excision is an attractive option for cosmesis and airway compromise, the associated neuropathy can be extremely difficult to treat and can be quite debilitating.
