madelung 's disease is characterised by multiple disfiguring abnormal fat masses in the head , the neck , and the radix of upper limbs ; in 90% of cases it 's associated with alcohol abuse . the local injections of phosphatidylcholine / deoxycholate solution have been gaining an increasing consensus as a non - invasive method to shrink localized adiposities . the authors report their long term experience on the assessment of serial intralipotherapy with phosphatidylcholine / deoxycholate in two patients affected by madelung 's disease . two male patients suffering from madelung 's disease underwent serial intralipotherapy with phosphatidylcholine / deoxycholate ( lipostabil -nattermann pharma , cologne , germany ) . pre- and 6 months post - treatment dimensions were assessed by measuring three diameters in each lesion with a 7.5 mhz probe ultrasound ( us ) scan performed by the same operator . a 45-year - old man , smoker , without history of alcohol abuse , affected by multiple comorbidities , presented with symmetric huge lipomatosis of the head , neck , dorsum , posterior aspect of the arms and testicles . chest x - rays and head and neck magnetic resonance imaging ( mri ) confirmed the infiltrative distribution of the lipomatosis and excluded the involvement of the trachea and other deep structures . even if a previous surgical excision of some cervico - occipital adipose deposits had been successful , the patient , who was still physically and psychologically impaired , refused a further surgical treatment under general anaesthesia of the remaining untreated adipose deposits : these infiltrating masses were therefore addressed with serial intralesional lipostabil injections . under us scan control 5 ml of lipostabil were injected into the jugular , submandibular and right cheek masses , respectively . the injections were repeated monthly for an overall of three treatments per lesion [ figures 1 and 2 ] . case 1 , right cheek mass : ( a ) pre - treatment view ; ( b ) post - treatment view case 1 , submandibular and jugular masses : ( a ) pre - treatment view ; ( b ) post - treatment view a 49-year - old - man , with a history of alcohol abuse and multiple comorbidities presented with enormous bilateral axillary fat deposits and some unpleasant adipose deposits in the dorsum and the submental and supraclavear areas . the axillary masses were surgically addressed , with no evidence of recurrence at 4 years follow - up . three other smaller submental and bilateral supraclavear deposits were injected with 5 ml of lipostabil each under us scan control . the injections were repeated monthly for an overall of three treatments per lesion [ figures 3 and 4 ] . case 2 , bilateral supraclavear masses : ( a ) pre - treatment view ; ( b ) post - treatment view case 2 , submental mass : ( a ) pre - treatment view ; ( b ) post - treatment view a 45-year - old man , smoker , without history of alcohol abuse , affected by multiple comorbidities , presented with symmetric huge lipomatosis of the head , neck , dorsum , posterior aspect of the arms and testicles . chest x - rays and head and neck magnetic resonance imaging ( mri ) confirmed the infiltrative distribution of the lipomatosis and excluded the involvement of the trachea and other deep structures . even if a previous surgical excision of some cervico - occipital adipose deposits had been successful , the patient , who was still physically and psychologically impaired , refused a further surgical treatment under general anaesthesia of the remaining untreated adipose deposits : these infiltrating masses were therefore addressed with serial intralesional lipostabil injections . under us scan control 5 ml of lipostabil were injected into the jugular , submandibular and right cheek masses , respectively . the injections were repeated monthly for an overall of three treatments per lesion [ figures 1 and 2 ] . case 1 , right cheek mass : ( a ) pre - treatment view ; ( b ) post - treatment view case 1 , submandibular and jugular masses : ( a ) pre - treatment view ; ( b ) post - treatment view a 49-year - old - man , with a history of alcohol abuse and multiple comorbidities presented with enormous bilateral axillary fat deposits and some unpleasant adipose deposits in the dorsum and the submental and supraclavear areas . the axillary masses were surgically addressed , with no evidence of recurrence at 4 years follow - up . three other smaller submental and bilateral supraclavear deposits were injected with 5 ml of lipostabil each under us scan control . the injections were repeated monthly for an overall of three treatments per lesion [ figures 3 and 4 ] . case 2 , bilateral supraclavear masses : ( a ) pre - treatment view ; ( b ) post - treatment view case 2 , submental mass : ( a ) pre - treatment view ; ( b ) post - treatment view clinically , a significant progressive shrinkage together with a change from a soft to a harder consistency of the adipose masses was appreciated . no alterations were reported in serum lipid pattern 1 month after the last treatment . at 6 months follow - up all of the lesions appeared stable . dimension changes in the treated lesions as demonstrated by us scan 6 months after the treatment are reported in table 1 and figure 5 . no local and/or systemic side - effects were reported . in both patients , one treated lesion out of three showed a slow clinical progression and required surgical excision . all of the other treated lesions are clinically stable at 5 years follow - up . measures in centimetres of the three main diameters at us scan before and after 3 injections of lipostabil ultrasound scan images - case 1 , right cheek mass : ( a ) pretreatment ; ( b ) post - treatment madelung 's disease is a lipomatosis classified in type 1 , with adipose masses symmetrically distributed in the body and in type 2 , with a diffuse obese - like fat distribution . diagnosis is clinically based and mri , computed tomography , and us scan allow evaluation of the fat deposits distribution . our two cases belong to type 1 with evident deposits in the head and neck . both patients had their major masses surgically removed ; the smaller , but more visible ones were deliberately addressed non - surgically with lipostabil , in order to avoid or at least postpone further surgery . treatment of hyperlipidemias and fat emboli , but diffusely employed subcutaneously in an off - label regimen to reduce localised adiposity and the volume of lipomas . the off - label use of lipostabil for the treatment of localised adiposity is actually controversial in the literature . in 2010 , the united states food and drug administration ( fda ) cautioned medical spas against misleading consumers by false statements about drugs including phosphatidylcholine / deoxycholate that would eliminate fat in a procedure called  lipodissolve . the fda keeps encouraging health care professionals and consumers to report any side - effects with the use of these drugs to the fda 's medwatch adverse event reporting program . it is approved for cardiological use to reduce cholesterol in some countries in europe , though not including the united kingdom . until date , lipostabil is not available in the italian market as the product trade registration was no longer provided by the manufacturer since may the 20 2004 . nevertheless , in italy , by the law 94/1998 the clinical use of phosphatidylcholine / deoxycholate is currently allowed as a galenical under the following strict circumstances : the treatment should be tailored on one individual patient , the physician should provide the patient a fully informed consent and the prescription should provide both the patient 's identity data and a reference number to the physician 's medical archive . its lipolytic action seems to be based on stimulation of lipase activity , emulsification and transport of triglycerides and a detergent action by its two main components , both causing cell membrane lysis , inflammation , fibrosis and degeneration of fat tissue . in one case acute renal failure and liver dysfunction have been reported as severe systemic side - effects following a single high dose subcutaneous injection . recently , it has been suggested that phosphatidylcholine might eventually have some therapeutic role in some cancers as animal studies indicate that deficiencies in choline and phosphatidylcholine may disrupt cell membrane signal transduction in ways that could lead to various cancers . furthermore , there is ample evidence that liver cancer is promoted in various animals by choline - deficient diets , and it has been shown that excess choline has a protective effect against carcinogenesis . known safety limits of phosphatidylcholine / deoxycholate compound are 15 mg / kg . a successful experience of serial intralipotherapy with a blend of lidocaine , aminophillin , l - carnitine , phosphatidylcholine and deoxycholate solution for the treatment of one patient affected by madelung 's disease is reported . according to the literature common off - label use of phosphatidylcholine / deoxycholate compound for localised fat deposits ranges between 1000 and 250 mg / session . our choice of lipostabil dosage , therefore , considered both the fat masses size and those safety limits . our results objectively demonstrated an average reduction of 42.5% in the three us scan measured diameters in all of the treated lesions 6 months after the treatment [ table 2 and figure 5 ] . percentage reduction of the masses at us scan in the three main diameters the 5 years clinical follow - up demonstrated the long - term functional and cosmetic stable results in 66% of the treated lesions . the treatment also proved to be safe as serum lipid status was not modified at 1 month since the last infiltration session . in madelung 's disease , the surgical approach is always invasive and often risky both for the anatomical complexity of the involved areas ( cervico - facial regions ) and for these patients general conditions , which are poor most of the time . the objectively demonstrated efficacy and safety of the treatment at the employed dosage together with its easy execution confirm the role of lipostabil as a non - invasive palliative reasonable therapeutic opportunity in madelung 's disease and an alternative to surgery in the more awkward locations of the disease . the phosphatidylcholine / deoxycholate compound needs wide investigation for new treatment uses and long - term studies and hence that the recommended dose and safe application technique can be standardised . the use of  lipodissolve  products should be considered an experimental treatment and be performed under strict medical control for both therapeutical and cosmetic purposes . our experience might , therefore , further contribute to the investigation of limits and possibilities of the clinical use of phosphatidylcholine / deoxycholate in the treatment of localised adiposities of any nature . according to our experience the inclusion of phosphatidylcholine / deoxycholate intralesional intralipotherapy in the armamentarium for the palliative treatment of madelung 's disease might be recommended to reduce the volume and limit the growth of the pathological adipose masses and to restrict the aggressive and often unacceptable anatomical consequences of the disease .
madelung 's disease is characterised by multiple symmetric abnormal fat masses in the head , neck and upper limbs . surgical excision or liposuction is the only realistic available option , although palliative in nature . 
 the serial intralipotherapy with phosphatidylcholine / deoxycholate has been proposed as a non - invasive treatment of madelung 's disease . 
 the authors used serial intralipotherapy with phosphatidylcholine / deoxycholate in two patients affected by madelung 's disease . 
 three injections per lesion per patient were performed with 1 month 's interval . 
 pre- and 6 months post - treatment dimensions were assessed with ultrasound scan and patients were observed along a 5 years clinical follow - up . 
 a 42.5% average size reduction was reported in all treated lesions . 
 about 33% recurrence rate was observed in the 5 years follow - up . 
 we confirm the efficacy of intralipotherapy in the non - invasive palliative treatment of madelung 's disease , as a valid option to reduce the volume and limit the growth of the pathological adipose masses .
