Lipomatosis: A disorder characterized by the accumulation of encapsulated or unencapsulated tumor-like fatty tissue resembling LIPOMA.Lipomatosis, Multiple Symmetrical: A condition characterized by the growth of unencapsulated masses of ADIPOSE TISSUE symmetrically deposited around the neck, shoulders, or other sites around the body.Epidural Space: Space between the dura mater and the walls of the vertebral canal.Lipoma: A benign tumor composed of fat cells (ADIPOCYTES). It can be surrounded by a thin layer of connective tissue (encapsulated), or diffuse without the capsule.Adiposis Dolorosa: A rare disease characterized by multiple tumor-like fatty deposits that press on nerves in various sites causing pain and weakness. Often these lipoma-like structures are located on the trunk and limbs but not on the face and hands.Spinal Cord Diseases: Pathologic conditions which feature SPINAL CORD damage or dysfunction, including disorders involving the meninges and perimeningeal spaces surrounding the spinal cord. Traumatic injuries, vascular diseases, infections, and inflammatory/autoimmune processes may affect the spinal cord.Paraparesis: Mild to moderate loss of bilateral lower extremity motor function, which may be a manifestation of SPINAL CORD DISEASES; PERIPHERAL NERVOUS SYSTEM DISEASES; MUSCULAR DISEASES; INTRACRANIAL HYPERTENSION; parasagittal brain lesions; and other conditions.Spinal Diseases
Pelvic lipomatosis: The rare disease pelvic lipomatosis is most often seen in older obese black men with hypertension. In pelvic lipomatosis, abnormally dense deposits of otherwise apparently normal fat may be observed in the spaces of the pelvic area.Benign symmetric lipomatosis: Benign symmetric lipomatosis (also known as Benign symmetric lipomatosis of Launois–Bensaude, Madelung's disease, multiple symmetric lipomatosis and cephalothoracic lipodystrophy) is a cutaneous condition characterized by extensive symmetric fat deposits in the head, neck, and shoulder girdle area. The German surgeon Otto Wilhelm Madelung was the first to give a detailed description of the disorder.Epidural space: In the spine, the epidural space (from Ancient Greek ἐπί, "on, upon" + dura mater also known as "epidural cavity", "extradural space" or "peridural space") is an anatomic space that is the outermost part of the spinal canal. It is the space within the canal (formed by the surrounding vertebrae) lying outside the dura mater (which encloses the arachnoid mater, subarachnoid space, the cerebrospinal fluid, and the spinal cord).Lipoma: (ILDS D17.910)Cellulite: Cellulite (also known as adiposis edematosa, dermopanniculosis deformans, status protrusus cutis, gynoid lipodystrophy, and orange peel syndrome) is the herniation of subcutaneous fat within fibrous connective tissue that manifests topographically as skin dimpling and nodularity, often on the pelvic region (specifically the buttocks), lower limbs, and abdomen. Cellulite occurs in most postpubescent females.Canine degenerative myelopathy: Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS). Onset is typically after the age of 7 years and it is seen most frequently in the German shepherd dog, Pembroke Welsh corgi, and boxer dog, though the disorder is strongly associated with a gene mutation in SOD1 that has been found in 43 breeds as of 2008, including the wire fox terrier, Chesapeake Bay retriever, Rhodesian ridgeback, and Cardigan Welsh corgi.Cervical spine disorder: Cervical Spine Disorders are illnesses that are relatively detrimental to ones physical health. These ailments exist in the cervical spine which is made up of the upper first seven vertebrae, encasing and shielding the Spinal cord.
(1/104) The expression of a truncated HMGI-C gene induces gigantism associated with lipomatosis.
Rearrangements of the HMGI-C gene have frequently been detected in human benign tumors of mesenchymal origin, including lipomas. The HMGI-C protein has three AT-hook domains and an acidic COOH-terminal tail. The HMGI-C modifications consist in the loss of the C-tail and the fusion with ectopic sequences. Recent results show that the loss of the COOH-terminal region, rather than the acquisition of new sequences, is sufficient to confer to HMGI-C the ability to transform NIH3T3 cells. Therefore, transgenic mice carrying a HMGI-C construct (HMGI-C/T), containing only the three AT-hook domains, were generated. The HMGI-C/T mice showed a giant phenotype, together with a predominantly abdominal/pelvic lipomatosis, suggesting a pivotal role of the HMGI-C truncation in the generation of human lipomas. (+info)
(2/104) Endoscopic retrograde pancreatographic findings of pancreatic lipomatosis.
Pancreatic lipomatosis is characterized by fatty infiltration or replacement of the pancreas, and has been associated with many conditions. We recently experienced two cases of pancreatic lipomatosis in patients with pancreatic pseudocyst and a case of lipomatosis in diabetes mellitus. In these patients, abrupt obstruction of the main pancreatic duct with smooth tapering is a typical endoscopic retrograde pancreatography (ERP) finding of pancreatic lipomatosis and must be differentiated with pancreatic carcinoma.

(3/104) Extradural lipomatosis presenting with paraplegia.
An unusual case with spinal extradural lipomatosis in a non-obese and otherwise healthy man is reported. The patient presented with a history of weakness of legs which progressed to paraplegia over a 40 day period. (+info)
(4/104) Germline and germline mosaic PTEN mutations associated with a Proteus-like syndrome of hemihypertrophy, lower limb asymmetry, arteriovenous malformations and lipomatosis.
Germline PTEN mutations cause Cowden syndrome (CS) and Bannayan-Riley-Ruvalcaba syndrome (BRR), two hamartoma-tumour syndromes, and somatic PTEN alterations have been shown to participate, to a greater or lesser extent, in a wide variety of sporadic neoplasia. PTEN is a tumour suppressor and dual-specificity phosphatase which affects apoptosis via its lipid phosphatase activity in the phosphoinositol-3-kinase and AKT pathway as well as inhibiting cell spreading via the focal adhesion kinase pathway. CS and BRR share some features, such as hamartomas and lipomatosis. To determine whether other syndromes characterized by overgrowth and lipomas are part of the PTEN syndrome spectrum, we ascertained six individuals with overgrowth and lipomas but who did not meet the diagnostic criteria for CS or BRR. Five had Proteus syndrome and one, a Proteus-like syndrome. When germline DNA and DNA from at least one involved tissue per case were examined for PTEN mutations, only the Proteus-like patient was found to harbour a germline R335X mutation. Interestingly, a lipomatous mass, an epidermoid naevus and arteriovenous malformation tissue, all of which were sampled from physically distinct sites, were all found to carry a second hit R130X mutation on the allele opposite the germline R335X. Both mutations have been described in CS and BRR. We postulate that the second hit, R130X, occurred early in embryonic development and may even represent germline mosaicism. Thus, PTEN may be involved in Proteus-like syndrome with its implications for cancer development in the future. (+info)
(5/104) Spinal epidural lipomatosis in a human immunodeficiency virus-positive patient receiving steroids and protease inhibitor therapy.
We describe a patient who became cushingoid as a result of receiving steroid therapy for thrombocytopenia purpura and who then developed spinal epidural lipomatosis 4 months after he started receiving ritonavir as part of his therapy for human immunodeficiency virus infection. We believe that ritonavir may have contributed to the development of epidural lipomatosis and that clinicians should be aware of this possible association. (+info)
(6/104) Congenital infiltrating lipomatosis of the face: case report and literature review.
Congenital infiltrating lipomatosis of the face comprises a subgroup of lipomatous tumors. While rare, it remains a definite clinical entity. Its etiology is unknown. The tumor is congenital in origin and occurs in infancy or early childhood. It is poorly enveloped and characterized by diffuse infiltration of mature adipose tissue over normal muscle fibers, rapid growth, associated osseous hyperplasia, and a high recurrence rate after surgical intervention. Due to its diffuse infiltration and involvement of important facial structures, complete surgical excision is often impossible. A total of 14 cases of congenital infiltrating lipomatosis of the face was found in a literature review. Herein we present an additional case who had both diffuse infiltrating lipomatosis and a well-encapsulated lipoma on her left cheek. (+info)
(7/104) Cauda equina syndrome caused by idiopathic sacral epidural lipomatosis.
The patient, who was a non-obese woman with no predisposing conditions of lipomatosis, slowly developed cauda equina syndrome. Spinal magnetic resonance imaging (MRI) presented mass lesion of high intensity on T1-weighted image (WI) and an intermediate signal intensity in T2 WI in the epidural space of S1 to coccyges. It has been reported that most idiopathic epidural lipomatosis (IEDL) is observed in obese men, and all cases have involved the thoracic or lumbar region. This is the first report of a patient with cauda equina syndrome caused by idiopathic sacral epidural lipomatosis (EDL). (+info)
