Lipedema is an underdiagnosed syndrome of unclear etiology, characterized by symmetric painful enlargement of the buttocks and lower extremities, which spares the feet. This enlargement is caused by the deposition of adipose tissue. It was first described by Allen and Hines in 1940, who observed that it had a female predilection; patients commonly had an associated family history. We describe a patient with classic lipedema and multiple lipomas of her arms and trunk.

Adiposis dolorosa (AD) is a rare disorder of painful nodular subcutaneous fat accompanied by fatigue, difficulty with weight loss, inflammation, increased fluid in adipose tissue (lipedema and lymphedema), and hyperalgesia. Sequential compression relieves lymphedema pain; we therefore hypothesized that whole body cyclic pneumatic hypobaric compression may relieve pain in AD. To avoid exacerbating hyperalgesia, we utilized a touch-free method, which is delivered via a high-performance altitude simulator, the Cyclic Variations in Altitude Conditioning™ (CVAC™) process. As a pilot study, 10 participants with AD completed pain and quality of life questionnaires before and after 20-40 minutes of CVAC process daily for 5 days. Participants lost weight (195.5 ± 17.6-193.8 ± 17.3 lb; P = 0.03), and bioimpedance significantly decreased (510 ± 36-490 ± 38 ohm; P = 0.01). There was a significant decrease in scores on the Pain Catastrophizing Scale (P = 0.039), in average (P = 0.002), highest (P = 0.029), lowest (P = 0.04), and current pain severity (P = 0.02) on the Visual Analogue Scale, but there was no change in pain quality by the McGill Pain Questionnaire. There were no significant changes in total and physical SF-36 scores, but the mental score improved significantly (P = 0.049). There were no changes in the Pain Disability Index or Pittsburgh Sleep Quality Index. These data present a potential, new, noninvasive means of treating pain in AD by whole body pneumatic compression as part of the CVAC process. Although randomized, controlled trials are needed to confirm these data, the CVAC process could potentially help in treating AD pain and other chronic pain disorders.

A prospective single-center study with mail questionnaire – in most cases combined with clinical controls – was carried out in 112 patients with lipedema after a period from 8 months to nearly 7 years following liposuction in tumescent local anesthesia.

OBJECTIVE: To evaluate methods to assess peripheral edema for reliability, feasibility and correlation with the classic clinical assessment of pitting edema. DESIGN: Cross-sectional observational study. SETTING: Large primary care clinic in Marshfield, Wisconsin, USA. PARTICIPANTS: Convenience sample of 20 patients with type 2 diabetes and a range of edema severity, including patients without edema. METHODS: Eight methods of edema assessment were evaluated: (1) clinical assessment of pit depth and recovery at three locations, (2) patient questionnaire, (3) ankle circumference, (4) figure-of-eight (ankle circumference using eight ankle/foot landmarks), (5) edema tester (plastic card with holes of varying size pressed to the ankle with a blood pressure cuff), (6) modified edema tester (edema tester with bumps), (7) indirect leg volume (by series of ankle/leg circumferences), and (8) foot/ankle volumetry by water displacement. Patients were evaluated independently by three nurse examiners. RESULTS: Water displacement and ankle circumference had high inter-examiner agreement (intraclass correlation coefficient 0.93, 0.96 right; 0.97, 0.97 left). Agreement was inconsistent for figure-of-eight (0.64, 0.86), moderate for indirect leg volume (0.53, 0.66), and low for clinical assessments at all locations. Agreement was low for the edema testers but varied by the pressure administered. Correlation with the classic, subjective clinical assessment was good for the nurse-performed assessments and patient questionnaire. Ankle circumference and patient questionnaires each took 1 minute to complete. Other tools took >5 minutes to complete. CONCLUSIONS: Water displacement and ankle circumference showed excellent reliability; however, water displacement is a time-consuming measure and may pose implementation challenges in the clinical and clinical trial environments. Patient-reported level and frequency of edema, based on an unvalidated questionnaire, was generally well correlated with the physician assessment of edema severity and may prove to be another reliable and accurate method of assessing edema. Additional study is needed to evaluate the validity and responsiveness of these methods.

A lipedema is characterized by the bilateral and symmetrical en-largement of the lower limbs without the involvement of the feet and a negative Stemmer’s sign; it may cause skin hypothermia, alteration in the plantar support, and hyperalgesia. The current study aims to report a rare type of ulcerative lesion in a patient with lipolymphedema treated with a damp low-stretch bandage. The patient is a female, age 50, with a family history of lipedema, and who has suffered many episodes of erysipelas in the lower left limb for approximately 20 years. For over five years ulcers which are difficult to heal have appeared. She was treated with a damp low-stretch bandage and the healing of the wound has shown significant improvement. Ulcerative lesions are rare in lipolymphedema; however, their occurrence is associated with difficulties in healing.

The challenges of providing effective treatment for patients with lymphoedema-related disorders have never been more prominent. Conservative management of lymphoedema remains of central importance, however, there is increasing evidence that other therapies, such as surgical approaches, may have an important part to play in the arena of treatment. The findings from these proceedings highlight the potential role that surgical approaches, including liposuction, can have in transforming the lives of patients. Conservative approaches, while effective in many patients, do not provide a solution for some of the complex issues patients face, nor do they always provide sustained results even after periods of expensive, intensive treatment. Relatively little attention has been placed on the impact that lymphatic conditions have on the lives of patients and their families. However, research is beginning to show that patients’ health-related quality of life is significantly affected and that previously dismissed symptoms, such as pain, are a feature of the condition. Lymphoedema and lipoedema are both likely to have a deleterious effect on the body image of patients who live day-to-day with distorted limbs. Treatments such as liposuction have the potential to reverse some of the crippling effects of these disorders on the psychosocial health of patients. The indications from these proceedings are that this is an important and encouraging area of practice that must be considered as part of the armoury of treatment. Liposuction has often been viewed negatively by the lymphoedema community, who have been sceptical about its value and concerned for its safety. This document shows that when it is used appropriately, by well trained surgeons, it can be very effective. In fact, the area of liposuction now has a growing evidence base that rivals many of the other conservative areas of lymphoedema management. Management of lymphatic conditions demands that the professional groups begin to work together in a more collaborative way in order to develop treatments that really address the growing number of patients with these types of conditions.

Knowledge of both the morphology/ pathomorphology and physiology/pathophysiology of adipose tissue is limited and the behaviour of fat tissue has not been widely researched. Changes in adipose tissue (hyperplasia, hypertrophy and atrophy) are defined differently and, as a consequence, diagnostic failures frequently occur. Figure 1 shows the complicated regulatory mechanisms which are responsible for lipolysis and lipogenesis. Even if body weight is normal, appearance depends on the distribution of subcutaneous adipose tissue (Figure 2) . The amount of fat we carry and how we look are, in part, subject to fashion. What was still sexy several decades ago, a bigger waist and more on the hips, no longer corresponds to how we see perfection today. Figure 2 shows the different ideals of beauty — ‘Wonderwoman’, for example, where you can detect as little fat as possible. Recently, there has been a mania for slimness. In order to comply with the current trend in fashion, young girls starve or undergo surgical procedures to have the typical female fatty tissue removed.

Lipoedema is a disease characterised by an abnormal, circumscribed accumulation of subcutaneous fat, mainly in the lower extremities, in combination with oedema. This results in an obvious disproportion between the upper and lower half of the body, as well as pain (Figure 1). Although lipoedema was first described in 1940 by Allen and Hines in the United States of America, the discussion still continues today as to whether this disease really is an entity, with some clinicians even doubting that it exists. In the 1940s it was described as a symmetrical subcutaneous deposition of fat in the buttocks and lower legs, together with an accumulation of fluid that begins almost imperceptibly, progressing gradually. Lipoedema was often associated with weight gain and accentuated by orthostatic activity.

Lymphoedema is a debilitating, progressive and incurable pathological condition caused by a chronic imbalance between the production and transport of lymph within the lymphatic system. There are many reasons for this damage or disruption to the lymphatic system. Lymphoedema results in significant physical and psychological morbidity. Approximately 140–250 million people worldwide are affected by this condition, mostly in developing countries as a result of lymphatic filariasis, a parasitic infection transmitted by mosquitoes. In the majority of cases, treatment is non-curative, complex and requires a multidisciplinary clinical approach. Surgery takes place as a last resort when conservative treatment has proven ineffective to restore function, reduce comorbidity or the frequency of erysipelas attacks.

Lipoedema: a new therapy regimen b Lipoedema, a disease in women, is characterised by circumscribed accumulation of subcutaneous fat, mainly in the legs, with oedema, tension pain, tenderness and haematomas.

Only a limited number of studies on cellulite have been published in the international literature and many of them reach somewhat antithetical conclusions. Consequently, it is not yet possible to reconcile the extreme differences of opinion which have lingered on for years concerning the nature of this disorder, as well as its origin and even the most basic aspects of its histopathological classification. It does not even have a recognized name: in fact, the term 'cellulitis' is used in scientific English to indicate a spreading gangrenous infection of the subcutaneous cellular tissue. The other terms used from time to time [panniculitis, lipodystrophy, edematofibrosclerotic panniculitis (EFP), liposclerosis, lipoedema, etc.] have quite different morphological and pathogenetic connotations in general. Over the last few decades, three major conflicting theories have emerged in relation to the ethiopathogenesis of cellulite. These indicate, respectively, the following causes: 1. Oedema caused by excessive hydrophilia of the intercellular matrix. 2. A homeostatic alteration on a regional microcirculatory level; this pathogenetic theory is summarized in a synthetic and self-explanatory denomination: EFP. 3. A peculiar anatomical conformation of the subcutaneous tissue of women, different from male morphology. These theories must all now be updated in the light of recent advances on the sophisticated and composite physiopathology of the adipose organ - which acts not only as a control device which regulates the systematic equilibrium of energy and modulates the food intake and the metabolism of other tissue substrate through a multiple glandular secretion of hormones and parahormones.

OBJECTIVE: Many investigations and treatments exist for lower limb lymphoedema. We undertook a survey on the management of this condition by vascular surgeons and the resources available for its treatment in the UK. DESIGN: A questionnaire was designed to assess the management of lymphoedema. MATERIALS AND METHOD: A postal questionnaire was sent to all members of the The Vascular Society of Great Britain and Ireland. RESULTS: 251/440 (57%) consultant surgeons returned a completed questionnaire comprising 45.3% teaching hospital and 54.7% district general hospital (DGH) consultants. 77.9% of the consultants saw less than 10 patients annually with lymphoedema. The commonest causes of lymphoedema were primary lymphoedema (99.3%) and malignancy (37.1%). Lipoedema, a cause of limb swelling was only seen or recognised by 46.2% of the consultants. The commonest investigations performed were a duplex scan, lymphoscintigram, full blood count and urea and electrolytes. The common methods of confirming lymphoedema were either by lymphoscintigram (54.5%) or from a diagnosis of exclusion (33.7%). Lymphoedema physiotherapy was available only to 53.8% of the consultants. Surgery was performed by 10.5% of consultants. 73.4% of the consultants believed that lymphoedema is managed inadequately and 72.9% believed that resources are insufficient in the UK for this condition. CONCLUSION: In the UK the majority of vascular consultants see less than 10 patients annually with lymphoedema. Very few patients undergo confirmation of this diagnosis with non-invasive investigation and very few consultants perform surgery. Management of this condition is perceived by the consultants to be poor, with a lack of resources and particular shortage of lymphoedema physiotherapists. Centralisation of these services may be a way of improving this condition.

Combined decongestive therapy (CDT) in lipedema can only reduce edema, not the fat components; therefore only a portion of the symptoms can be treated. In contrast liposuction is able to reduce the increased volume of fatty tissue; it also decreases the tendency to develop edema. Only by combining conservative and surgical therapy regimens optimal results can be achieved. From the theoretical and practical point of view nowadays in lipedema grade I, II and partially grade III conservative treatment alone can be considered as an insufficient therapy.

Modern aspects of pathophysiology, epidemiology, symptoms, diagnosis and therapy in lipedema are presented. Within recent years the development of new techniques in local anaesthesia and surgery has revolutionized therapy. By using surgical and conservative methods (tumescent liposuction and combined decongestive therapy) a normalization of body proportions and a reduction of subjective and objective symptoms with a distinct improvement in the quality of life can be achieved.

Painful fat syndrome or lipoedema is a distinct clinical condition, characterised by bilateral and symmetrical enlargement of the upper and lower leg with tenderness, but excluding the feet. Lipoedema occurs almost exclusively in females, and no male patient has been reported in the literature published in English. We report on an extremely rare presentation of lipoedema in a male patient. A thorough study based on the case history, physical manifestations, and magnetic resonance imaging (MRI) provided valuable clues for a differential diagnosis. Conservative treatment using weight reduction, compression-stocking application, and diuretic therapy was not effective. Tumescent liposuction with postoperative pressure garments provided a satisfactory treatment.

Up until recently, complex physical therapy has been the mainstay in treatment of lipedema. This generally improved edema and reduced pain and tension in affected patients. More recently, surgical approaches such as liposuction have been used to reduce the fat volume under tumescent local anesthesia. Combining both methods, dramatic improvements can be achieved in treating the disease and in improving the quality of life. However liposuction in lipedema should only be performed in specialized medical centers.

HYPOTHESIS: The causes and management of lower limb lymphedema in the Western population are different from those in the developing world. OBJECTIVE: To look at the differential diagnosis, methods of investigation, and available treatments for lower limb lymphedema in the West. DATA SOURCE: A PubMed search was conducted for the years 1980-2002 with the keyword "lymphedema." English language and human subject abstracts only were analyzed, and only those articles dealing with lower limb lymphedema were further reviewed. Other articles were extracted from cross-referencing. RESULTS: Four hundred twenty-five review articles pertaining to lymphedema were initially examined. This review summarizes the findings of relevant articles along with our own practice regarding the management of lymphedema. CONCLUSIONS: The common differential diagnosis in Western patients with lower limb swelling is secondary lymphedema, venous disease, lipedema, and adverse reaction to ipsilateral limb surgery. Lymphedema can be confirmed by a lymphoscintigram, computed tomography, magnetic resonance imaging, or ultrasound. The lymphatic anatomy is demonstrated with lymphoscintigraphy, which is particularly indicated if surgical intervention is being considered. The treatment of choice for lymphedema is multidisciplinary. In the first instance, combined physical therapy should be commenced (complete decongestive therapy), with surgery reserved for a small number of cases.

"Lipedema," a special form of obesity syndrome, represents swelling of the legs due to an increase of subcutaneous adipose tissue. In 12 patients with lipedema of the legs and in 12 healthy subjects (controls), fluorescence microlymphography was performed to visualize the lymphatic capillary network at the dorsum of the foot, at the medial ankle, and at the thigh. Microaneurysm of a lymphatic capillary was defined as a segment exceeding at least twice the minimal individual diameter of the lymphatic vessel. In patients with lipedema, the propagation of the fluorescent dye into the superficial lymphatic network of the skin was not different from the control group (p > 0.05). In all 8 patients with lipedema of the thigh, microaneurysms were found at this site (7.9 +/- 4.7 aneurysms per depicted network) and in 10 of the 11 patients with excessive fat involvement of the lower leg, multiple microlymphatic aneurysms were found at the ankle region. Two obese patients showed lymphatic microaneurysms in the unaffected thigh and in only 4 patients were microaneurysms found at the foot. None of the healthy controls exhibited microlymphatic aneurysms at the foot and ankle, but in one control subject a single microaneurysm was detected in the thigh. Multiple microlymphatic aneurysms of lymphatic capillaries are a consistent finding in the affected skin regions of patients with lipedema. Its significance remains to be elucidated although its occurrence appears to be unique to these patients.
