    Lipoma Arborescens of the Knee: Report of Three Cases and Review of the Literature.
    Case Rep Med 2017 24;2017:3569512. Epub 2017 Jan 24.
    Department of Orthopaedics, 424 General Military Hospital, Ring Road N. Efkarpias, 56403 Thessaloniki, Greece.
    Lipoma arborescens is a chronic, slow-growing, intra-articular lesion of benign nature, which is characterized by villous proliferation of the synovium, with replacement of the subsynovial connective tissue by mature fat cells. It usually involves the suprapatellar pouch of the knee joint. It is not a neoplasm but is rather considered a nonspecific reactive response to chronic synovial irritation, due to either mechanical or inflammatory insults. Read More

    Subcutaneous Midline Nasal Mass in an Infant due to an Intramuscular Lipoma.
    Pediatr Dermatol 2017 Feb 27. Epub 2017 Feb 27.
    Division of Pediatric Dermatology, Nationwide Children's Hospital and Ohio State University Medical Center, Columbus, Ohio.
    Intramuscular lipomas are rare, benign, mesenchymal tumors occurring deep in the fascia, typically involving large muscle groups in adults. We report a case of an intramuscular lipoma occurring as a subcutaneous midline nasal mass in a 3-month-old infant. The differential diagnosis of a midline mass on the glabella of an infant is important and should include developmental anomalies such as nasal glioma, nasal dermoid cyst, and encephalocele, so neuroimaging is an essential first step in evaluating these lesions to exclude intracranial extension.

    HMGA2 immunostaining is a straightforward technique which helps to distinguish pulmonary fat-forming lesions from normal adipose tissue in small biopsies: a retrospective observational study about a series of 13 lung biopsies.
    Diagn Pathol 2017 Feb 23;12(1):21. Epub 2017 Feb 23.
    Department of Pathology, Rouen University Hospital, F 76 000 Rouen, France.
    Background: A tracheobronchial lesion observed during an endoscopic examination is usually sampled by the pulmonologist and sent to the pathologist for microscopic examination. Adipocytes may be observed in the lamina propria of tracheobronchial biopsies, which may complicate diagnosis of sampled lesions because these adipose cells may be part of the lesion (lipoma or pulmonary hamartoma), but may also be a normal component of the bronchial mucosa. Because endoscopic samples frequently miss their target, adipocytes observed in such biopsies usually lead to uncertainty regarding diagnosis. Read More

    Colonic intussusception in descending colon: An unusual presentation of colon lipoma.
    Gastroenterol Hepatol Bed Bench 2016 Dec;9(Suppl1):S93-S96
    Gastroenterology and Liver Diseases Research Center, Research Institute for Gastroenterology and Liver Diseases, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
    Lipomas of the colon are relatively rare benign soft tissue tumors derived from mature adipocytes of mesenchymatic origin.

    The Enigma of "Traumatic Pseudolipoma" and "Traumatic Herniation of Buccal Fat Pad": A Systematic Review and New Classification System of Post-Traumatic Craniofacial Fatty Masses.
    J Oral Maxillofac Surg 2017 Feb 1. Epub 2017 Feb 1.
    Professor and Head of Department, Oral Health Sciences Centre; Professor-in-Charge, Academic Section, Post Graduate Institute of Medical Education and Research, Chandigarh, India.
    Purpose: Intraoral traumatic herniation of the buccal fat pad has been reported using various terms such as traumatic pseudolipoma, traumatic prolapse of buccal fat pad, and traumatic avulsion of buccal fat pad. Because there is no uniformity in nomenclature, this condition needs to be distinguished from other entities such as post-traumatic pseudolipoma and lipoma and pseudoherniation of the buccal fat pad.

    Materials And Methods: A systematic review and thorough search of the literature was planned in online databases such as PubMed, Medline, Scopus, Embase, and Google Scholar. Read More

    Ossified dysraphic hamartoma with lipomyelocoele/lipomyelomeningocoele-A rare radiological entity.
    Clin Imaging 2017 Jan 31;43:60-63. Epub 2017 Jan 31.
    Department of Radiology, Emory University, Atlanta, GA, United States.
    Traditionally the presence of fat in closed spinal dysraphism has been referred to as spinal lipoma. Recent reports suggest that these spinal lesions are better described as spinal hamartomas due to the unencapsulated and infiltrating nature of the fat and presence of other heterotopic soft tissue. The presence of ossified bone in spinal hamartomas referred to as ossified dysraphic hamartoma, is extremely rare with only three case reports in literature, all associated with lipomyeloceles, none with lipomyelomeningoceles.
