Lipedema is a condition characterized by abnormal deposition of adipose tissue in the lower extremities leading to circumferential bilateral lower extremity enlargement typically seen extending from the hips to the ankles. Diagnosis of the condition is often challenging, and patients frequently undergo a variety of unsuccessful therapies before receiving the proper diagnosis and appropriate management. Patients may experience pain and aching in the lower extremity in addition to distress from the cosmetic appearance of their legs and the resistance of the fatty changes to diet and exercise. We report a case of a patient with lipedema who was treated with suction-assisted lipectomy and use of compression garments, with successful treatment of the lipodystrophy and maintenance of improved aesthetic results at 4-year postoperative follow-up.

Rare adipose disorders (RADs) including multiple symmetric lipomatosis (MSL), lipedema and Dercum's disease (DD) may be misdiagnosed as obesity. Lifestyle changes, such as reduced caloric intake and increased physical activity are standard care for obesity. Although lifestyle changes and bariatric surgery work effectively for the obesity component of RADs, these treatments do not routinely reduce the abnormal subcutaneous adipose tissue (SAT) of RADs. RAD SAT likely results from the growth of a brown stem cell population with secondary lymphatic dysfunction in MSL, or by primary vascular and lymphatic dysfunction in lipedema and DD. People with RADs do not lose SAT from caloric limitation and increased energy expenditure alone. In order to improve recognition of RADs apart from obesity, the diagnostic criteria, histology and pathophysiology of RADs are presented and contrasted to familial partial lipodystrophies, acquired partial lipodystrophies and obesity with which they may be confused. Treatment recommendations focus on evidence-based data and include lymphatic decongestive therapy, medications and supplements that support loss of RAD SAT. Associated RAD conditions including depression, anxiety and pain will improve as healthcare providers learn to identify and adopt alternative treatment regimens for the abnormal SAT component of RADs. Effective dietary and exercise regimens are needed in RAD populations to improve quality of life and construct advanced treatment regimens for future generations.

BACKGROUND: Lipoedema is a painful disease in women with circumscribed increased subcutaneous fatty tissue, oedema, pain and bruising. Whereas conservative methods with combined decongestive therapy (manual lymphatic drainage, compression garments) have been well established over the past 50years, surgical therapy with tumescent liposuction has only been used for about 10years and long-term results are unknown. OBJECTIVES: To determine the efficacy of liposuction concerning appearance (body shape) and associated complaints after a long-term period. METHODS: A total of 164 patients who had undergone conservative therapy over a period of years, were treated by liposuction under tumescent local anaesthesia with vibrating microcannulas. In a monocentric study, 112 could be re-evaluated with a standardized questionnaire after a mean of 3years and 8months (range 1year and 1month to 7years and 4months) following the initial surgery and a mean of 2years and 11months (8months to 6years and 10months) following the last surgery. RESULTS: All patients showed a distinct reduction of subcutaneous fatty tissue (average 9846mL per person) with improvement of shape and normalization of body proportions. Additionally, they reported either a marked improvement or a complete disappearance of spontaneous pain, sensitivity to pressure, oedema, bruising, restriction of movement and cosmetic impairment, resulting in a tremendous increase in quality of life; all these complaints were reduced significantly (P<0·001). Patients with lipoedema stage II and III showed better improvement compared with patients with stage I. Physical decongestive therapy could be either omitted (22·4% of cases) or continued to a much lower degree. No serious complications (wound infection rate 1·4%, bleeding rate 0·3%) were observed following surgery. CONCLUSIONS: Tumescent liposuction is a highly effective treatment for lipoedema with good morphological and functional long-term results.

Liposuction is an integral part of the wide range of surgical procedures in dermatology. Dermatologists established tumescent local anesthesia in combination with the use of micro-cannulas; especially dermatologists from Germany and Austria actively designed and developed these new techniques. In this position paper, we discuss the history, various interdisciplinary aspects, the significance, and the treatment indications for this procedure as well as its role within dermatologic training programs and research. For quality reasons, members of the Germany Society of Dermatologic Surgery and the Austrian Society of Dermatologic Surgery discuss several fundamental professional aspects as well as the historical development of liposuction.

Background: Elevated stearoyl-CoA desaturase activity has been described in obese states, with an increased desaturation index (DI) suggesting enhanced lipogenesis. Differences in the DI among various phenotypes of abnormal adiposity have not been studied. Abnormal accumulation of subcutaneous adipose tissue occurs in rare adipose disorders (RADs) including Dercum’s disease (DD), multiple symmetric lipomatosis (MSL), and familial multiple lipomatosis (FML). Examining the DI in subcutaneous fat of people with DD, MSL and FML may provide information on adipose tissue fatty acid metabolism in these disorders. The aims of this pilot study were: 1) to determine if differences in adipose tissue DIs are present among RADs, and 2) to determine if the DIs correlate to clinical or biochemical parameters. Methods: Subcutaneous adipose tissue was obtained from human participants with DD (n = 6), MSL (n = 5), FML (n = 8) and obese Controls (n = 6). Fatty acid composition was determined by gas chromatography/mass spectrometry. The DIs (palmitoleic/palmitic, oleic/stearic, vaccenic/stearic ratios) were calculated from the gas chromatogram peak intensities. SCD1 gene expression was determined. Spearman’s correlations between the DIs and available clinical or biochemical data were performed. Results: In DD subjects, the vaccenic/stearic index was lower (p < 0.05) in comparison to Controls. Percent of total of the saturated fatty acid myristic acid was higher in DD compared with Controls and FML. Percent of monounsaturated vaccenic acid in DD trended lower when compared with Controls, and was decreased in comparison to FML. In MSL, total percent of the polyunsaturated fatty acids was significantly lower than in the Control group (p < 0.05). In the total cohort of subjects, the palmitoleic/palmitic and oleic/stearic DIs positively correlated with age, BMI, and percent body fat. Conclusions: The positive associations between the DIs and measures of adiposity (BMI and percent body fat) support increased desaturase activity in obesity. The lower vaccenic/stearic DI in DD SAT compared with Controls suggests presence of other factors involved in fat accumulation in addition to lifestyle. Other mechanisms driving fat accumulation in DD such as inflammation or lymphatic dysfunction should be investigated.

Lipedema is a chronic disease of lipid metabolism that results in the symmetrical impairment of fatty tissue distribution and storage combined with the hyperplasia of individual fat cells. Lipedema occurs almost exclusively in women and is usually associated with a family history and characteristic features. It can be diagnosed based on clinical history and physical examination. Lipedema is usually symmetrical, but spares the feet, is often painful to palpation, and is negative for Stemmer's sign. Additionally, lipedema patients can present with microangiopathies and lipomas. The well-known therapies for lipedema include complex decongestive therapy, pneumatic compression, and diet modifications. However, whether these treatments help reduce swelling is debatable. We encountered a case of lipedema that was initially misdiagnosed as lymphedema. The patient's clinical features and history were different from those typical of lymphedema, prompting a diagnosis of lipedema and she was treated with a complex decongestive therapy program.

Lipedema is a disproportional obesity featuring light pressure-induced or spontaneous pain. On the basis of our clinical observations, lymphedema therapy, as practiced in our clinic, reduces the perception of pain beyond leg volume reduction. We therefore aimed to measure pain intensity prior and subsequent to treatment. 38 women with lipedema were enrolled in the study with 19 patients undergoing treatment and 19 serving as the control group using exclusively moisturizers. Treatment consisted of once daily manual lymph drainage (MLD), intermittent pneumatic compression (IPC), and multilayered short-stretch bandaging performed throughout a 5-day-course. Pain was evaluated with a 10-item questionnaire, a pain rating scale (PRS), and the Wong-Baker Faces scale. Treatment resulted in a significant reduction of pain with a decrease in mean scores of all three measures. In the control group, only PRS showed significant decrease. Our study results indicate that this treatment regimen not only reduces leg volume and capillary fragility, but also improves pain intensity in patients with lipedema.

Lymphedema and lipedema are chronic progressive disorders for which no causal therapy exists so far. Many general practitioners will rarely see these disorders with the consequence that diagnosis is often delayed. The pathophysiological basis is edematization of the tissues. Lymphedema involves an impairment of lymph drainage with resultant fluid build-up. Lipedema arises from an orthostatic predisposition to edema in pathologically increased subcutaneous tissue. Treatment includes complex physical decongestion by manual lymph drainage and absolutely uncompromising compression therapy whether it is by bandage in the intensive phase to reduce edema or with a flat knit compression stocking to maintain volume.

BACKGROUND: There are many causes for a large lower limb in the pediatric age group. These children are often mislabeled as having lymphedema, and incorrect diagnosis can lead to improper treatment. The purpose of this study was to determine the differential diagnosis in pediatric patients referred for lower extremity "lymphedema" and to clarify management. METHODS: The authors' Vascular Anomalies Center database was reviewed between 1999 and 2010 for patients referred with a diagnosis of lymphedema of the lower extremity. Records were studied to determine the correct cause for the enlarged extremity. Alternative diagnoses, sex, age of onset, and imaging studies were also analyzed. RESULTS: A referral diagnosis of lower extremity lymphedema was given to 170 children; however, the condition was confirmed in only 72.9 percent of patients. Forty-six children (27.1 percent) had another disorder: microcystic/macrocystic lymphatic malformation (19.6 percent), noneponymous combined vascular malformation (13.0 percent), capillary malformation (10.9 percent), Klippel-Trenaunay syndrome (10.9 percent), hemihypertrophy (8.7 percent), posttraumatic swelling (8.7 percent), Parkes Weber syndrome (6.5 percent), lipedema (6.5 percent), venous malformation (4.3 percent), rheumatologic disorder (4.3 percent), infantile hemangioma (2.2 percent), kaposiform hemangioendothelioma (2.2 percent), or lipofibromatosis (2.2 percent). Age of onset in children with lymphedema was older than in patients with another diagnosis (p = 0.027). CONCLUSIONS: "Lymphedema" is not a generic term. Approximately one-fourth of pediatric patients with a large lower extremity are misdiagnosed as having lymphedema; the most commonly confused causes are other types of vascular anomalies. History, physical examination, and often radiographic studies are required to differentiate lymphedema from other conditions to ensure the child is managed appropriately.

BACKGROUND: Lipedema is a painful, genetically induced abnormal deposition of subcutaneous fat in the extremities of almost exclusively women. The pathogenesis is unknown and no curative treatment is available. Conservative therapy consisting of lymphatic drainage and compression stockings is often recommended, but is only effective against the edema. Some patients show a short-term improvement when treated in this way. The removal of the increased fat tissue of lipedema has become possible by employing advanced liposuction techniques which utilize vibrating microcannulas under tumescent local anesthesia. The effectiveness of this approach to lipedema is the subject of this study. PATIENTS AND METHODS: 25 patients were examined before liposuction and six months thereafter. The survey included the measurement of the volume of the legs and several parameters of typical pain and discomfort. The parameters were measured using visual analogue scales (VAS, scale 0-10). RESULTS: The volume of the leg was reduced by 6.99 %. Pain, as the predominant symptom in lipedema, was significantly reduced from 7.2 ± 2.2 to 2.1 ± 2.1 (p < 0.001). Quality of life as a measure of the psychological strain caused by lipedema improved from 8.7 ± 1.7 to 3.6 ± 2.5 (p < 0.001). Other parameters also showed a significant improvement and the over-all severity score improved in all patients. CONCLUSION: Liposuction reduces the symptoms of lipedema significantly.

At the 3rd International Lymphoedema Framework (ILF) conference in Toronto, an attempt was made to begin to try to address this issue. Over thirty people attended a lipoedema workshop run by the author. In this workshop, I had the opportunity to talk to this international group (Canada, USA, Netherlands, Australia, UK, Germany) who shared their experiences from across the world. One of the goals of the workshop was to create an initial broad consensus about the worldwide diagnosis and management of lipoedema.The outcomes of that workshop are presented in the following report.

OBJECTIVE. The objective of our study was to examine the frequency and significance of visualization of popliteal nodes during lymphoscintigraphy for the investigation of lower extremity swelling. MATERIALS AND METHODS. Technetium-99m–labeled nanocolloid was injected subcutaneously in the first web spaces of both feet of 204 consecutive patients (69 males, 135 females; age range, 11–79 years) undergoing routine, clinically indicated lymphoscintigraphy; imaging was performed 5, 45, and 150 minutes after injection. The patients were asked not to undertake any vigorous exercise between the injection and completion of imaging. RESULTS. No popliteal nodes were visualized in 29 patients in whom there was no evidence of lymphedema on clinical or lymphoscintigraphic examination (group 1). Unilateral or bilateral popliteal nodes were visualized in 10 of 39 patients (25.6%) with clinical evidence of lymphedema but normal lymphoscintigraphy findings (group 2) (p < 0.005 vs group 1). In 136 patients with clinical evidence of lymphedema and abnormal lymphoscintigraphy findings (group 3), unilateral or bilateral popliteal nodes were visualized in 59 (43.4%) (p < 0.0001 vs group 1). Popliteal nodes were visualized in 40 of 73 limbs with “dermal backflow” (54.8%) and 42 of 335 limbs without dermal backflow (12.5%) (p < 0.0001). CONCLUSION. Popliteal node visualization after subcutaneous foot web space injection is an important sign of abnormal lymphatic function in patients with clinical lymphedema of the lower extremities.

It is estimated that 3.5 million patients, both male and female, suffer from a congenital lipid distribution disorder of the arms and legs. Because these lipid distribution disorders are painful, owing to a lymphological high volume insufficiency and a structural drainage incompetence, the term lipohyperplasia dolorosa has become established as the name for the clinical picture of lipoedema. This lymphological clinical picture has also undergone a paradigm change with regard to the therapeutic options over the last 15 years: lipohyperplasia dolorosa is curable. This four part series reports on the principles and successes in operative lymphology. Zusammenfassung Geschätzt werden 3,5 Millionen PatientInnen, die an einer angeborenen Fettverteilungsstö-rung der Beine und Arme leiden. Da diese Fettverteilungsstörungen aufgrund einer lym -phologischen Hochvolumeninsuffizienz und einer strukturellen Drainageschwäche schmerzhaft ist, hat sich der Begriff Lipo-hyperplasia dolorosa zur Bezeichnung des Krankheitsbildes Lipödem durchgesetzt. Auch in Bezug auf die therapeutischen Optionen erlebte dieses lymphologische Krankheitsbild in den letzten 15 Jahren einen Paradigmenwechsel: Lipohyperplasia dolorosa ist heilbar. In einer vierteiligen Serie wird über Grundlagen und Erfolge der operativen Lymphologie berichtet werden.
