Lymphedema is the chronic, progressive swelling of tissue due to inadequate lymphatic function. Over time, protein-rich fluid accumulates in the tissue causing it to enlarge. Lymphedema is a specific disease and should not be used as a generic term for an enlarged extremity. The diagnosis is made by history and physical examination, and confirmed with lymphoscintigraphy. Intervention includes patient education, compression, and rarely, surgery. Patients are advised to exercise, maintain a normal body mass index, and moisturize / protect the diseased limb from incidental trauma. Conservative management consists of compression regimens. Operative interventions either attempt to address the underlying lymphatic anomaly or the excess tissue. Lymphatic-venous anastomosis and lymph node transfer attempt to create new lymphatic connections to improve lymph flow. Suction-assisted lipectomy and cutaneous excision reduce the size of the area by removing fibroadipose hypertrophy.

Lipedema is a lymphedema-masquerading symmetrical, bilateral and disproportional obesity. Its conservative maintenance treatment comprises the use of flat-knitted compression pantyhoses. Lipedema is known to be associated with left ventricular morphological and functional alterations. The present study aimed to assess the effects of graduated compression stockings on left ventricular (LV) rotational mechanics measured by three-dimensional speckle-tracking echocardiography (3DSTE) in lipedema patients. The present study comprised twenty lipedema patients (mean age: 45.8 ± 11.0 years, all females) undergoing 3DSTE who were also compared to 51 age- and gender-matched healthy controls (mean age: 39.8 ± 14.1 years, all females). 3DSTE analysis was performed at rest, and subsequent to 1 hour application of compression class 2 made-to-measure flat-knitted pantyhose. Six lipedema patients showed significant LV rotational abnormalities. Of the remaining fourteen lipedema patients LV basal rotation rotation showed significant reduction, while LV apical rotation showed significant increase with unchanged LV twist after a 60-minute use of compression garment. Significant changes in LV rotational mechanics could be detected among 14 women with lipedema after the use of compression garment however six probands have special LV rotational abnormalities at baseline and/or after compression.

AIM: To assess imaging findings and characteristics of the lymphatic system in patients affected by lipedema and lipolymphedema of the lower extremities on Non-Contrast MR Lymphography (NCMRL). MATERIALS AND METHODS: 44 lower extremities in 11 consecutive female patients affected by lipedema, and 11 patients with lipolymphedema were examined by NCMRL. MR imaging was performed on 1.5-T system MR equipment. The examination consisted of one 3D short-tau inversion recovery (STIR) and one heavily T2-weighted 3D-Turbo Spin Echo (TSE) sequence. RESULTS: All patients showed symmetrical enlargement of the lower extremities with increased subcutaneous fat tissue. The fat tissue was homogeneous, without any signs of edema in pure lipedema patients. In all the extremities with lipolymphedema, high signal intensity areas in the epifascial region could be detected on the 3D-TSE sequence (p < .001) with evidence of mild epifascial fluid collections (p < .001). No sign of honeycomb pattern fat appearance was observed. The appearance of the iliac lymphatic trunks was normal in both lipedema and lipolymphedema patients. Dilated peripheral lymphatics were observed in 2 patients affected by lipedema, indicating a subclinical status of lymphedema, and in 10 patients with lipolymphedema (p = .001). Signs of vascular stasis were observed in both groups, without statistically significant difference (p = .665). CONCLUSION: NCMRL is a non-invasive imaging technique that is suitable for the evaluation of patients affected by lipedema and lipolymphedema, helping in the differential diagnosis.

BACKGROUND: Lipedema is a common adipose tissue disorder affecting women, characterized by a symmetric subcutaneous adipose tissue deposition, particularly of the lower extremities. Lipedema is usually underdiagnosed, thus remaining an undertreated disease. Importantly, no histopathologic or molecular hallmarks exist to clearly diagnose the disease, which is often misinterpreted as obesity or lymphedema. MATERIALS AND METHODS: The aim of the present study is to characterize in detail morphologic and molecular alterations in the adipose tissue composition of lipedema patients compared with healthy controls. Detailed histopathologic and molecular characterization was performed using lipid and cytokine quantification as well as gene expression arrays. The analysis was conducted on anatomically matched skin and fat tissue biopsies as well as fasting serum probes obtained from 10 lipedema and 11 gender and body mass index-matched control patients. RESULTS: Histologic evaluation of the adipose tissue showed increased intercellular fibrosis and adipocyte hypertrophy. Serum analysis showed an aberrant lipid metabolism without changes in the circulating adipokines. In an adipogenesis gene array, a distinct gene expression profile associated with macrophages was observed. Histologic assessment of the immune cell infiltrate confirmed the increased presence of macrophages, without changes in the T-cell compartment. CONCLUSIONS: Lipedema presents a distinguishable disease with typical tissue architecture and aberrant lipid metabolism, different to obesity or lymphedema. The differentially expressed genes and immune cell infiltration profile in lipedema patients further support these findings.

Lipoedema is associated with widespread adipose tissue expansion, particularly in the proximal extremities. The mechanisms that drive the development of lipoedema are unclear. In this Perspective article, we propose a new model for the pathophysiology of lipoedema. We suggest that lipoedema is an oestrogen-dependent disorder of adipose tissue, which is triggered by a dysfunction of caveolin 1 (CAV1) and subsequent uncoupling of feedback mechanisms between CAV1, the matrix metalloproteinase MMP14 and oestrogen receptors. In addition, reduced CAV1 activity also leads to the activation of ERα and impaired regulation of the lymphatic system through the transcription factor prospero homeobox 1 (PROX1). The resulting upregulation of these factors could effectively explain the main known features of lipoedema, such as adipose hypertrophy, dysfunction of blood and lymphatic vessels, the overall oestrogen dependence and the associated sexual dimorphism, and the mechanical compliance of adipose tissue.

Liposuction is one of the most common procedures undertaken in plastic surgery with a steadily increasing trend over the years. Although usually performed as an aesthetic procedure for body contouring, it can also be utilized in specific patient groups for disease symptom reduction. One such disease entity is lipedema. The goal of this video to present the authors' technique in the surgical treatment of lipedema, and to offer the viewer a better understanding of the differences between an aesthetic liposuction and a functional liposuction as performed on a lipedema patient. Between July 2009 and July 2019, 106 lipedema patients have been treated in the authors' specialized lipedema clinic, with a total of 298 liposuction procedures and a median follow-up of 20 months. The mean amount of lipoaspirate was 6354.73 ml (± 2796.72 ml). The patients reported a significant reduction in lipedema-associated complaints and improvement in quality of life. The need for conservative therapy was significantly reduced. No serious complications were reported. The authors also present before and after photographs of three patients.

BACKGROUND: The aim was to quantify and to compare the associations between longitudinal changes in pain and depression in different chronic pain conditions. METHODS: Data were retrieved from 6 observational cohort studies. From baseline to the 6-month follow-up, the score changes on the Short Form (36) Health Survey (SF-36) bodily pain (pain) and the SF-36 mental health (depression) scales (0=worst, 100=best) were quantified, using partial correlations obtained by multiple regression. Adjustment was performed by age, living alone/with partner, education level, number of comorbidities, baseline pain and baseline depression. RESULTS: Stronger associations were found between changes in levels of pain and depression for neck pain after whiplash (n = 103, mean baseline pain=21.4, mean baseline depression=52.5, adjusted correlation r = 0.515), knee osteoarthritis (n = 177, 25.4, 64.2, r = 0.502), low back pain (n = 134, 19.0, 49.4, r = 0.495), and fibromyalgia (n = 125, 16.8, 43.2, r = 0.467) than for lower limb lipedema (n = 68, 40.2, 62.6, r = 0.452) and shoulder arthroplasty (n = 153, 35.0, 76.4, r = 0.292). Those correlations were somewhat correlated to baseline pain (rank r=-0.429) and baseline depression (rank r=-0.314). LIMITATIONS: The construct of the full range of depressive symptoms is not explicitly covered by the SF-36. CONCLUSIONS: Moderate associations between changes in pain and depression levels were demonstrated across 5 of 6 different chronic pain conditions. The worse the pain and depression scores at baseline, the stronger those associations tended to be. Both findings indicate a certain dose-response relationship - an important characteristic of causal interference. Relieving pain by treatment may lead to the relief of depression and vice versa.

Lipoedema, an adipose tissue disorder, is a poorly visible, often unrecognised condition. To foster a greater understanding of the significant and debilitating impacts faced by women living with lipoedema, the charity Lipoedema UK conducted four focus group interviews, the findings of which were published in a series of reports under the umbrella title 'Women in dire need'. The reports identified the substantial and numerous negative effects of lipoedema on the women's everyday lives, including the patients' experiences with compression garments, the effects of liposuction surgery (many of which were not positive), the everyday impacts ranging from pain and reduced mobility to poor self-esteem and working prospects, and the considerable challenges faced by women with late-stage lipoedema which can render them immobile.

Lipoedema is an incurable chronic disease causing limb deformity, painful skin and excessive ecchymosis. Compression garments are frequently recommended to manage symptoms, but the existing products are not designed specifically for lipoedema, and are for other medical conditions. A structured questionnaire was prepared in Online Surveys in October 2018 to investigate lipoedema symptoms and the use of compression garments to manage them. Some 279 people with lipoedema completed the survey; 70% wore compression garments in all four compression classes, of which class 2 was most common (58% of wearers). The top three reasons for wearing compression garments were to feel supported (73%), reduce lipoedema pain (67%) and improve mobility (54%). Most people with lipoedema who wore compression garments found compression helpful in managing their symptoms, but overall satisfaction was low. Problems with existing compression garments were so severe in some cases that the garments were not worn at all or used less often. The information collected in this survey might be useful for the design and development of compression garments specifically for lipoedema.

BACKGROUND: Lipedema is a chronic, progressive disorder of subcutaneous adipose tissue that usually affects the lower extremities of women. Also known as "two-body syndrome," the fat accumulations in lipedema are unsightly and painful. The disorder is well-known in Europe but is largely unrecognized and underdiagnosed in the United States. OBJECTIVE: To hold the First International Consensus Conference on Lipedema with the purpose of reviewing current European guidelines and the literature regarding the long-term benefits that have been reported to occur after lymph-sparing liposuction for lipedema using tumescent local anesthesia. METHODS: International experts on liposuction for lipedema were convened as part of the First International Congress on Lipedema in Vienna, Austria, June 9 to 10, 2017. RESULTS: Multiple studies from Germany have reported long-term benefits for as long as 8 years after liposuction for lipedema using tumescent local anesthesia. CONCLUSION: Lymph-sparing liposuction using tumescent local anesthesia is currently the only effective treatment for lipedema.

Purpose: Upper limb lymphedema is a vexing morbidity that can occur after the treatment for breast cancer. The Lymphedema Functioning, Disability and Health Questionnaire for Upper Limb Lymphedema (Lymph-ICF-UL) is a valid and reliable tool assessing problems in functioning in patients with breast cancer-related lymphedema. Until now, a French-language version was lacking. The aim of this study was to perform a cross-cultural validation of the French version of the Lymph-ICF-UL questionnaire.Methods: A forward-backward translation process between the original language (Dutch) and the target language (French) was performed. Psychometric properties of this final French version were examined in 50 participants.Results: Intraclass correlation coefficients for test-retest reliability ranged from 0.66 to 0.95. Cronbach's alpha coefficients for internal consistency were higher than 0.77. Face and content validity were very good because the scoring system was clear for all participants (100%), questions were understandable (100%), and all complaints due to BCRL were mentioned by 78% of the participants. Construct validity was moderate. Convergent validity was established since 3 out of 5 expected domains of the Lymph-ICF-UL showed a moderate correlation with expected domains of the 36-item Short-Form Health Survey. There was satisfactory divergent validity as 6 out of 9 hypotheses assessing divergent validity were accepted.Conclusion: The French version of the Lymph-ICF-UL is a reliable and valid questionnaire and ready for use in clinical as well as in scientific practice.Implications for rehabilitationSince the introduction of more effective treatment modalities increasing the number of breast cancer survivors, the amount of patients dealing with lymphedema is rising likewise up to a pooled incidence rate of more than 16% of the women treated for breast cancer.The French version of the Lymph-ICF-UL is a reliable and valid questionnaire for assessing problems in functioning of patients with breast cancer-related lymphedema of the arm and/or hand.As the questionnaire provides patient information in the different domains of the International Classification of Functioning, Disability and Health, it facilitates evaluating the impact of breast cancer-related lymphedema on daily functioning.Based on the outcomes of the Lymph-ICF-UL treatment goals can be set, where after the questionnaire can be used to monitor long-term results of this treatment and self-care.

Lipedema is a clinical condition in which there is abnormal swelling of body parts which may be confused with lymphedema and obesity. Allen and Hines first coined this term in 1940. It commonly affects lower limbs in symmetrical pattern. However asymmetric lipedema cases are reported also. Women are commonly affected. Diagnosis is mostly clinical. Imaging has important role in diagnosis and differentiating from closely related differentials. Conservative and surgical treatment are usually recommended. It is often misdiagnosed due to lack of proper knowledge and investigated in an inappropriate way. Here, we report a 36–years–old woman presenting with unilateral thigh swelling for 1 year. She had localized lipedema of left thigh and was advised for consultation with plastic surgery department.

Einleitung: Die Diagnostik des Lipödems basiert bislang auf rein klinischen Befunden, objektive Parameter fehlen bislang. Ziel dieser Studie ist es, einen möglichen Zusammen-hang zwischen einer standardisierten, sonographisch gemessenen Kompressibilität der subkutanen Fettschicht sowie dem Vergleich der Hautfettfalten an Abdomen und Oberschenkel und der klinischen Diagnose Lipödem aufzuzeigen. Material und Methode: Das Grundkollektiv zur Probandinnen-Auswahl bestand aus 1100 Patientinnen und Patienten. Davon wurden 1016 Patientinnen und Patienten wegen zutreffender Ausschlusskriterien ausgeschlossen. Die verbliebenen 84 Patientinnen wurden auf die klinische Diagnose „Lipödem der Beine“ untersucht. Die klinische Diagnose „Lipödem“ war bei 71 Patientinnen positiv und bei 13 Patientinnen negativ. Insgesamt haben drei Patientinnen die Teilnahme verweigert (eine mit negativer Diagnose, zwei mit positiver Diagnose); damit wurden 69 Patientinnen in der Gruppe der Lipödempatientinnen und zwölf Patientinnen in der Kontrollgruppe untersucht. Zudem wurden als weitere Kontrollgruppe sieben männliche „gesunde“ Probanden mit derselben Technik vermessen und verglichen. An Daten wurden für alle Probandinnen und Probanden das Alter, BMI, Verhältnis von Abdomen- zu Oberschenkelhautfettfalte (nur rechts), Subkutisdicke am Oberschenkel unkomprimiert und komprimiert auf beiden Seiten erhoben. Resultate: Die Annahme, dass die Subkutis bei Lipödempatientinnen deutlich geringer kompressierbar ist, konnte an 69 Lipödempatientinnen, die keinerlei Lymphödemsymptomatik zeigten, verifiziert werden. Die Kontrollgruppen (sieben Männer, zwölf Frauen) verhielten sich diesbezüglich negativ. Der Mittelwert dieser Kompressibilität lag in der Lipödemgruppe bei 7 %, in den Kontrollgruppen bei 22 % (Männer) bzw. 16 % (Frauen ohne Lipödem). Das Verhältnis der Hautfettfalten an Abdomen und Oberschenkel war bei Lipödempatientinnen mit im Mittel 0,43 signifikant unter den anderen Gruppen (Männer: 1,45; Frauen ohne Lipödem: 1,16). Diskussion: Die sonographisch gemessene Kompressibilität der Subkutis stellt einen wichtigen, objektiven Parameter zur Diagnostik des Lipödems dar. Eine zusätzliche positive Aussage liefert zudem der Vergleich der Hautfettfaltendicke an Abdomen und Oberschenkel mit statistisch signifikanten Unterschieden.

BACKGROUND: Although a large number of adult women worldwide are affected by lipedema, the physiologic conditions triggering onset and progression of this chronic disease remain enigmatic. In the present study, a descriptive epidemiologic situation of postoperative lipedema patients is presented. METHODS: The authors developed an online survey questionnaire for lipedema patients in Germany. The survey was conducted on 209 female patients who had been diagnosed with lipedema and had undergone tumescent liposuction. RESULTS: Most of the participants (average age, 38.5 years) had noticed a first manifestation of the disease at the age of 16. It took a mean of 15 years to accomplish diagnosis. Liposuction led to a significant reduction of pain, swelling, tenderness, and easy bruising as confirmed by the majority of patients. Hypothyroidism [n = 75 (35.9 percent) and depression [n = 48 (23.0 percent)] occurred at a frequency far beyond the average prevalence in the German population. The prevalence of diabetes type 1 [n = 3 (1.4 percent)], and diabetes type 2 [n = 2 (1 percent)] was particularly low among the respondents. Forty-seven of the lipedema patients (approximately 22.5 percent) suffered from a diagnosed migraine. Following liposuction, the frequency and/or intensity of migraine attacks became markedly reduced, as stated by 32 patients (68.1 percent). CONCLUSIONS: Quality of life increases significantly after surgery with a reduction of pain and swelling and decreased tendency to easy bruising. The high prevalence of hypothyroidism in lipedema patients could be related to the frequently observed lipedema-associated obesity. The low prevalence of diabetes, dyslipidemia, and hypertension appears to be a specific characteristic distinguishing lipedema from lifestyle-induced obesity.

Obesity is a worldwide major public health problem with an alarmingly increasing prevalence over the past 2 decades. The consequences of obesity in the skin are underestimated. In this paper, we review the effect of obesity on the skin, including how increased body mass index affects skin physiology, skin barrier, collagen structure, and wound healing. Obesity also affects sebaceous and sweat glands and causes circulatory and lymphatic changes. Common skin manifestations related to obesity include acanthosis nigricans, acrochordons, keratosis pilaris, striae distensae, cellulite, and plantar hyperkeratosis. Obesity has metabolic effects, such as causing hyperandrogenism and gout, which in turn are associated with cutaneous manifestations. Furthermore, obesity is associated with an increased incidence of bacterial and Candida skin infections, as well as onychomycosis, inflammatory skin diseases, and chronic dermatoses like hidradenitis suppurativa, psoriasis, and rosacea. The association between atopic dermatitis and obesity and the increased risk of skin cancer among obese patients is debatable. Obesity is also related to rare skin conditions and to premature hair graying. As physicians, understanding these clinical signs and the underlying systemic disorders will facilitate earlier diagnoses for better treatment and avoidance of sequelae.
