Ana Cláudia Cavalcante Esposito, Tania Munhoz, Luciana Patrícia Fernandes Abbade, Hélio Amante Miot
A 57-year-old female showed bulky, loose tumors, which progressively spread to her arms, anterior chest, and back. She reported dysphagia and dyspnea after mild exertion. She denied alcohol consumption. CT scan of her chest showed no internal lesions. Benign symmetric lipomatosis is a rare syndrome, clinically described as multiple nonencapsulated lipomas of various sizes and symmetrical distribution. This syndrome has three known phenotypes; in type 2 (Launois-Bensaude syndrome), lesions occur primarily on the shoulders, upper arms, and chest, and is unrelated to alcoholism...

Despite considerable progress in identifying causal genes for lipodystrophy syndromes, the molecular basis of some peculiar adipose tissue disorders remains obscure. In an Israeli-Arab pedigree with a novel autosomal recessive, multiple symmetric lipomatosis (MSL), partial lipodystrophy and myopathy, we conducted exome sequencing of two affected siblings to identify the disease-causing mutation. The 41-year-old female proband and her 36-year-old brother reported marked accumulation of subcutaneous fat in the face, neck, axillae, and trunk but loss of subcutaneous fat from the lower extremities and progressive distal symmetric myopathy during adulthood...

UNLABELLED: Lipomas are the most common benign soft tissue mesenchymal tumours composed of mature adipose tissue. They are uncommon in the oral and maxillofacial regions, with 15-20 % of cases involving the head and neck region and less than 5% of all benign oral lesions. Multiple symmetric lipomatosis is rare and characterized by diffuse growth and nonencapsulated lipomas. It is usually found in the posterior neck and upper trunk and they are relatively infrequent on the oral and maxillofacial regions like Madelung disease...

Symmetric lipomatosis is definitively characterized by symmetric, tumorous lipomatous proliferation of adipose tissue that often develops in the head and neck, shoulders, and upper trunk. However, in the oral region, symmetric lipomatosis of the tongue (SLT) is an extremely rare condition related to generalized lipidosis that is often caused by chronic alcoholism. It is characterized by multiple symmetric lipomatous nodules and diffuse bilateral swelling located within the tongue. We report an extremely rare case of SLT arising in an 80-year-old man with a long history of alcoholic liver cirrhosis...

OBJECTIVE: The aim of this study was to characterize adipose-derived stromal cells (ADSCs) from patients diagnosed with multiple symmetric lipomatosis (MSL) in order to obtain potentially new insights into the pathophysiology, pathogenesis and treatment of this disease. METHODS: Cells from the stromal vascular fraction were analysed by the colony-forming efficiency assay and flow cytometry using standard markers. Moreover, the power of adipogenic plasticity was evaluated...

BACKGROUND: The cause of the rare fat distribution disorder multiple symmetric lipomatosis is unknown. Independent reports suggest a higher proliferative activity, hormone resistance, and involvement of mitochondrial function in the disease. METHODS: The authors performed morphologic comparison of affected and unaffected tissues in five unrelated patients and generated adipose-derived stem cell cultures from the tissue samples and characterized them as a possible cellular model of multiple symmetric lipomatosis evolution...

Multiple symmetric lipomatosis is rare and characterized by diffuse growth and nonencapsulated lipomas. It is usually found in the posterior neck and upper trunk, and the entity is known as "benign symmetric lipomatosis," "Madelung disease," and "Launois-Bensaude syndrome." Symmetric lipomatosis of the tongue was first described by Desmond and is an extremely rare condition. A 74-year-old man complained of painless tongue swelling and difficulty speaking. Clinical findings revealed no tumor masses on the trunk, limbs, or head and neck region...

Acoustic waves are mechanical waves recently used to activate tissue metabolism by exploiting the cell permeabilization caused by their passage. We report a case of a retroauricular lipoma in a 44-year-old woman affected by multiple symmetric lipomatosis and treated with extracorporeal acoustic wave therapy. The adipose thickness of the lipoma was reduced from 35.8 to 21 mm, with increased softness at palpatory examination.

Multiple symmetric lipomatosis (MSL) is a rare disease characterized by symmetric and abnormal distribution of subcutaneous adipose tissue (SAT); however, the etiology is largely unknown. We report here that miR-125a-3p and miR-483-5p are upregulated in the SAT of MSL patients, promoting adipogenesis through suppressing the RhoA/ROCK1/ERK1/2 pathway. TaqMan microRNA (miR) array analysis revealed that 18 miRs were upregulated in the SAT of MSL patients. Transfection of human adipose-derived mesenchymal stem cells (hADSCs) with the individual agomirs of these 18 miRs showed that miR-125a-3p and miR-483-5p significantly promoted adipogenesis...

Multiple symmetric lipomatosis (MSL) is a mitochondrial disorder with impaired brown fat metabolism that has been associated with MERRF mutations in some, but not all, patients. We studied a sibling pair and an unrelated indiviadual who presented with MSL and neuropathy to determine the genetic etiology of this disorder in patients who did not carry the MSL-associated MERRF mutation. Whole-exome sequencing was performed on the siblings, and a rare, shared homozygous mutation in MFN2 (c.2119C>T: p.R707W) was identified...

UNLABELLED: Madelung's disease is a rare fat metabolism disorder characterised by benign multiple symmetric, encapsulated lipomatosis. The exact cause of the disease is unknown; it may be associated with chronic alcoholism and mutations in mitochondrial DNA (A8344G), but there have been cases without these factors reported in the literature. A 29-year-old man with a 6-year history of diabetes mellitus was admitted to our hospital for poorly regulated diabetes and decreased libido. He was not an alcohol consumer...

Multiple symmetric lipomatosis (MSL), or Madelung's disease, is a rare disease of unknown etiology. It is characterized by the presence of loose adipose tissue deposits localized in the cervical region and upper body. MSL presenting as bilateral huge gynecomastia is an extremely rare phenomenon. The present report describes a case of MSL in a 66-year-old man. The patients presented with bilateral breast bulging. He had a history of cigarette and alcohol use. His condition was treated with a bilateral nipple-sparing mastectomy...

The term Michelin tire baby (MTB), named for the cartoon mascot of the Michelin Tire Company, has been used to describe babies with multiple symmetric circumferential rings of folded skin. In those reported with this phenotype who had skin biopsies, pathology has shown nevus lipomatosis, smooth muscle hamartoma, degenerative collagen, and scarring. Others did not undergo biopsy or had normal skin. Many individuals with the MTB phenotype have had a variety of other congenital anomalies. I review the literature on MTB and the history of the designation Michelin tire baby Syndrome (MTBS)...

BACKGROUND: Multiple symmetric lipomatosis (MSL) is a rare condition leading to grotesque disfigurement. Complete removal is almost impossible and recurrences inevitable. The objective of this study was to evaluate powered-assisted liposuction (PAL) for the treatment of MSL. METHODS: Magnetic resonance imaging (MRI) was performed before and after surgery for quality assessment. To exclude malignancy incisional biopsies were taken before surgery. Outcome measures included aspiration volumes, duration of surgery, early morbidity, recurrence rates, and overall patient satisfaction...

Madelung's disease, also known as benign symmetric lipomatosis (BSL), multiple symmetric lipomatosis (MSL), fatty neck syndrome or Launois-Bensaude syndrome, is a rare disease characterized by the presence of multiple, symmetric, loose adipose tissues distributed around the neck, occipitalis, shoulder, back or chest. The fat masses are non-encapsulated and therefore can move freely between adjacent areas. This disease is most commonly seen among middle-aged Caucasian men of Mediterranean origins; it is rarely reported in Asia...
