Rare Presentation of Dercum's Disease in a Child with Abnormalities in Lipoprotein Metabolism

Differential Diagnosis of a Case of Dercum's Disease with Possible Familial Involvement and Review of Literature

Dercum's disease (DD), also described as adiposis dolorosa, is a poorly understood and rare adipose tissue disorder involving obesity and painful adipose tissue masses. Patients may have associated bruising and constitutional symptoms such as fatigue, difficulty concentrating, and sleep disturbance. DD was initially described in 1888 by Francis Xavier Dercum, and was classified into four subtypes, including generalized diffuse, generalized nodular, localized nodular, and juxta-articular subtypes. While this disease has been described for more than 130 years, its etiology and treatment remain elusive. We describe a case of a patient with DD who presented to Ochsner Medical Center, New Orleans, LA, for evaluation of treatment options. We review current knowledge on this rare disease and data on modern treatment methods.

Metabolic and immunological phenotype of rare lipomatoses: Dercum's disease and Roch-Leri mesosomatic lipomatosis

Context

Dercum’s disease (DD) and Roch-Leri mesosomatic lipomatosis (LMS) are rare and poorly characterized diseases. The clinical presentation combines multiple lipomas, painful in DD in contrast with LMS, without lipoatrophy.

Objective

To identify any specific metabolic and immune phenotype of DD and LMS.

Design and patients

This monocentric retrospective study included 46 patients: 9 DD, 11 LMS, 18 lean and 8 obese controls. Metabolic and immunohematological characteristics of each group were compared.

Results

The median age of the patients was similar in the 3 groups (31 years). The number of women, and of basophils, and CD3⁺, CD4⁺ and CD8⁺ T lymphocytes was significantly higher in the DD versus the LMS group, without any difference of the metabolic parameters. Weight, BMI, blood pressure, gamma-GT, leptin, fasting insulin and C-peptide levels, fat mass percentage, and intra/total abdominal fat ratio were significantly higher in each lipomatosis group compared with the lean group. Compared with the lean group, the DD group had significantly higher fasting blood glucose, LDL-cholesterol, platelets, leukocytes, basophils, and a lower NK cell count, whereas the LMS group had a significantly lower rate of CD3, CD4, and CD8 lymphocytes. Compared with the obese controls, basophils remained higher in DD and T lymphocytes subpopulations lower in LMS groups.

Conclusion

DD and LMS show a common background of obesity and metabolic phenotype, but a distinct immunohematological profile characterized by a higher number of basophils in DD patients, an inflammatory profile that could contribute to pain. T lymphocyte depletion was present in LMS. These findings could offer specific therapeutic opportunities, especially for painful DD.

Rare Forms of Lipomatosis: Dercum's Disease and Roch-Leri Mesosomatous Lipomatosis

In contrast to obesity, which is very frequent, lipomatosis and lipodystrophy syndromes are rare diseases of adipose tissue. Lipodystrophy syndromes are characterized by metabolic abnormalities associated with partial or generalized lipoatrophy. Lipomatosis is defined by the presence of several body lipomas without lipoatrophy. Dercum’s disease (DD) and Roch-Leri mesosomatous lipomatosis (RLML) are rare and poorly characterized forms of lipomatosis. They have raised little clinical interest despite the non-negligible consequences of DD on quality of life. The main clinical presentation of these diseases includes multiple lipomas, which are painful in DD (in contrast to RLML). The two diseases are frequently associated with obesity and metabolic syndrome, with hypertension, diabetes, or dyslipidemia. The long-term course of the diseases remains poorly described. DD affects mainly women, whereas RLML mostly affects men. In both diseases lipomas are found on the back and thighs, as well as on the abdomen in DD and the forearms in RLML. The painful lipomas tend to recur after surgery in DD (in contrast to RLML). Most cases are sporadic. No specific treatment has been identified, as the pathophysiology remains unknown. Nevertheless, low-grade fat inflammation and specific abnormalities such as hyperbasophilia deserve further investigation. The aim of this review is to analyze the available literature on the topic.

Dercum's disease (adiposis dolorosa): a review of clinical presentation and management

Dercum's disease (adiposis dolorosa) is a rare disease of unknown etiology characterized by painful subcutaneous adipose tissue deposits with various localization over the body. The deposits occur histologically as lipomas and are associated with overweight or obesity and a variety of psychiatric disturbances (anxiety, depression, sleep disturbances). Classification of Dercum's disease is related to size and location of adipose nodules (generalized diffuse, generalized nodular, localized nodular and juxta-articular forms). Diagnosis in based on clinical presentation and exclusion of a number of other disorders associated with lipomas. There is no generally accepted management of the patients. Liposuction or lidocaine application has been reported successful in some cases. Other therapeutic methods have been reported but their effectiveness is based on anecdotal descriptions only, and were not confirmed in clinical trials.
