Dercum's disease is a rare and chronic condition characterized by the presence of painful lipomas (benign fatty tumors), usually found in multiples throughout the adipose tissue of the body. The disease often coexists with obesity and is more frequently diagnosed in middle-aged women, especially those who are postmenopausal. Dercum's disease was first described in 1892 by American neurologist Francis Xavier Dercum at Jefferson Medical College. The condition was historically referred to as Adiposis dolorosa, but this term is now considered obsolete, and Dercum’s disease is recognized as a distinct entity separate from conditions such as lipedema or multiple symmetric lipomatosis.

Signs and symptoms

The clinical presentation of Dercum’s disease is highly variable, but it typically includes a combination of the following cardinal features:

• Chronic pain in the adipose tissue
• Obesity or abnormal fat distribution
• Fatigue and muscle weakness
• Emotional instability, which may include depression, anxiety, confusion, and occasionally dementia or epilepsy

Additional signs and associated symptoms that have been reported in patients with Dercum’s disease include:

• Easy bruising
• Sleep disturbances
• Cognitive impairment, including memory and concentration issues
• Palpitations or tachycardia
• Joint pain and muscle aches
• Shortness of breath
• Constipation and bloating
• Diabetes mellitus or glucose intolerance

Due to the heterogeneity of symptoms, there is no universally accepted diagnostic criterion. However, a proposed “minimal definition” includes:

1. Generalized overweight or obesity
2. Chronic pain in subcutaneous fat or lipomas

Classification

While not universally categorized, researchers have proposed different clinical subtypes of Dercum's disease based on the distribution of painful lipomas:

• Generalized diffuse – widespread pain in adipose tissue without clear lipomas
• Generalized nodular – widespread pain with identifiable, painful nodules
• Localized nodular – limited areas of painful nodules
• Juxta-articular – painful deposits near joints

Causes

The exact etiology of Dercum's disease remains unknown. Several theories have been proposed, including:

• Dysfunction of the autonomic nervous system
• Inflammatory or immune-mediated abnormalities in adipose tissue
• Mechanical compression of peripheral nerves by lipomas
• Hormonal factors related to menopause
• Trauma as a triggering event in some cases

Diagnosis

Diagnosis of Dercum’s disease is clinical and often based on exclusion. There are no definitive laboratory or imaging tests for the condition. Diagnosis is generally made based on:

• Chronic pain in fatty tissue
• Presence of lipomas
• Associated features such as obesity, fatigue, and emotional changes
• Absence of other conditions (e.g., lipedema, fibromyalgia, hypothyroidism)

Imaging studies such as ultrasound or MRI may assist in identifying lipomas but are not required for diagnosis.

Differential diagnosis

Differential diagnoses include:

• Lipedema
• Fibromyalgia
• Multiple symmetric lipomatosis
• Benign symmetric lipomatosis
• Hypothyroidism
• Polymyalgia rheumatica

Treatment

There is no known cure for Dercum’s disease, and treatment is symptomatic. Management strategies include:

Medications

• Nonsteroidal anti-inflammatory drugs (NSAIDs)
• Analgesics and opioids for severe pain
• Antidepressants and anticonvulsants for neuropathic pain
• Corticosteroids for inflammation (limited evidence)

Non-pharmacologic therapies

• Physical therapy and occupational therapy
• Psychotherapy or counseling for emotional symptoms
• Supportive therapies such as acupuncture or massage therapy

Surgical options

• Excision of particularly painful lipomas
• Liposuction to reduce fat volume (results vary)

Prognosis

Dercum’s disease is a chronic condition with a variable course. While it is not typically life-threatening, it can lead to significant morbidity, disability, and decreased quality of life. Pain and fatigue are often persistent, and management typically requires a multidisciplinary approach.

Epidemiology

Dercum’s disease is considered a rare disorder. It is more common in women than men, particularly in the age range of 35 to 60 years. Exact prevalence data is lacking due to underdiagnosis and misclassification.

History

Francis Xavier Dercum first described the condition in 1892, identifying a syndrome characterized by painful adipose deposits in obese individuals. The term “Adiposis dolorosa” was originally used but has since been largely abandoned in favor of “Dercum’s disease” as understanding of related disorders has evolved.
