Computed tomography (CT) continues to become more widely available for assessment of tumors in dogs, yet there are no studies describing the CT appearance of canine liposarcomas. In this retrospective, multicenter study, CT images of dogs with histologically confirmed liposarcomas were reviewed for size, location, attenuation, contrast enhancement, border definition, internal homogeneity, local infiltration, and mineralization. A total of 24 dogs with 26 liposarcomas were sampled. Mean attenuation was +15.2 (SD = 22...

INTRODUCTION: The scapula is not an uncommon site for bone and soft tissue tumours and can be difficult to delineate on examination. Furthermore, these lesions can be potentially challenging to biopsy due to its close anatomical relationship with important structures. We present an epidemiological survey of all the scapular and periscapular lesions presenting to our institution. METHODOLOGY: This was a retrospective study with data obtained from a prospectively held electronic database over a 30-year period...

OBJECTIVES: The purpose of this study was to compare the sonographic findings of angio lipomas with those of superficial lipomas. METHODS: Preoperative sonograms of 26 angiolipomas from 18 patients and 47 superficial lipomas from 43 patients that were confirmed by biopsy were reviewed retrospectively. The echo texture, echogenicity, internal echogenic stranding, vascularity, visualization of lateral and superficial-deep tumor capsules, shape, and tumor length, width, and length-to-width ratio were evaluated and compared between angiolipomas and superficial lipomas...

CONTEXT: Anatomical variations of the filum terminale (FT) have been described in association with split cord malformations (SCM) but they appear to be a rare finding in its absence. We report the first case in literature of a duplicated FT in a patient presenting with tethered cord syndrome (TCS) without any radiological evidence of SCM. FINDINGS: A 47-year-old man presented with invalidating back pain radiating to both legs. Magnetic resonance imaging revealed an intradural dorsal lipoma in a low-lying conus...

This case report illustrates the potential fallacy of attributing a patient's symptoms to an incidental finding. Serial imaging of small, asymptomatic cerebellopontine angle (CPA) lipomas is favored. It is imperative to accurately diagnose CPA lipoma on imaging and differentiate it from more common CPA lesions. We herein present a patient with symptoms consistent with Bell's palsy and an incidental finding of a CPA lipoma. Additionally, we performed a review of the literature for case reports of patients presenting with facial symptoms and diagnosed with a CPA lipoma...

Esophageal lipoma is an uncommon benign tumor of the esophagus and accounts for only 0.4% of all benign neoplasms of the gastrointestinal system. The majority of these are located in the cervical part; only very few are located in the lower third of the esophagus. We discuss the case of a 37-year-old female who presented with dysphagia and an esophageal lipoma located in the lower third of the esophagus. The patient underwent right mini-thoracotomy and enucleation of lipoma. Histopathologic examination revealed adipose tissue with a collection of matured adipose tissue...

Esophageal squamous cell carcinoma (ESCC) is the commonest primary malignant esophageal tumor, which typically presents as endoscopically visible surface mucosal ulcerations, irregularities, or polyploidal masses. We here report a rare case of primary ESCC with completely intramural growth under a normal looking intact nondysplastic surface squamous epithelium disguising as a submucosal tumor. Upper gastrointestinal endoscopy-guided mucosal biopsy was negative for malignancy. Endoscopic ultrasound (EUS) revealed a heteroechoic solid mass originating from the muscularis propria of the distal esophagus...

PURPOSE: To determine non-radiographic risk factors differentiating atypical lipomatous tumors (ALTs) from lipomas. METHODS: All patients with deep-seated lipomatous tumors of the extremities treated from January 2000 to October 2010 were retrospectively reviewed. Factors reviewed included age, gender, tumor location, size, histology, local recurrence, dedifferentiation, and metastasis. Multivariate logistic regression models were used to evaluate the effects of patient characteristics on ALT status...

The current tissue sampling techniques for subepithelial tumors (SETs) of the gastrointestinal (GI) tract have limited diagnostic efficacy. We evaluated the diagnostic yield and safety of forceps biopsies after small endoscopic submucosal dissection (SESD biopsies) in the diagnosis of gastric SETs. A total of 42 patients with gastric SETs > 10 mm were prospectively enrolled between May 2013 and October 2014. A dual knife was used to incise the mucosa and submucosa and forceps biopsies were then introduced deep into the lesion...

INTRODUCTION: Intraosseous lipomas are the most infrequent primary bone tumor, lesions are mainly asymptomatic and generally diagnosed incidentally, and there is controversy about the management. Here, we present a surgery solution that has not been described previously in literature. CASE PRESENTATION: A 23-year-old female without previous morbid history consults a general physician because of unspecific left hip pain when walking, not related to any previous trauma or any other symptoms...

Adipose lesions rarely affect the peripheral nerves. This can occur in two different ways: Direct compression by an extraneural lipoma, or by a lipoma originated from the adipose cells located inside the nerve. Since its first description, many terms have been used in the literature to mention intraneural lipomatous lesions. In this article, the authors report a case of a 62-year-old female who presented with an intraneural median nerve lipoma and review the literature concerning the classification of adipose lesions of the nerve, radiological diagnosis and treatment...

INTRODUCTION: Intussusception in adult is rarely caused by idiopathic conditions. Main causes are inflammatory diseases, benign or malignant tumors and motility disorders. As a benign cause, lipomas appear as a particularly rare gastrointestinal intraluminal tumor occurring with highest incidence in the colon, mostly in the caecum and ascending colon. PRESENTATION OF CASE: A 57-year-old male patient was admitted at the surgical emergency in Belo Horizonte, with history of chronic and intermittent diffuse abdominal pain, associated with variations of his bowel habits and rare episodes of vomiting starting around 3days prior to admission...

INTRODUCTION: Angiomyxolipoma (AML) is a rare variant of benign lipoma with characteristic histopathological and immuno-histochemical features. It consists of fatty tissue admixed with myxoid stroma and blood vessels. It was first described by Mai et al. in 1996 [1], with a total number of 19 cases reported since. PRESENTATION: This is the first report of an AML in subcutaneous tissue of the face, presenting as a 4-month old cystic lesion in a 78-year old lady. Diagnosis was based on radiological and histopathological with cytochemical findings...

OBJECTIVES: Spindle cell lipomas (SCLs) are benign lipomatous neoplasms that classically arise in the posterior neck, upper back, and shoulders of older male patients. We sought to characterize the occurrence of this entity at nonclassic sites. METHODS: All cases of SCL arising at atypical sites were retrieved from our archives. RESULTS: Of 439 total cases of SCL, 57 arose at atypical locations in 32 men and 25 women (age range, 27-79 years)...

Lipoma rarely involves parotid gland especially in children. An 11-year-old boy presented with right parotid swelling. Preoperative workup including CT scan and FNAC gave suspicion of parotid gland lipoma. The diagnosis was confirmed on histopathology after complete excision of the mass.

GOALS: To further characterize the gastrointestinal manifestations of Cowden syndrome in clinically well-annotated patients to improve the diagnosis of this syndrome. BACKGROUND: The gastrointestinal manifestations of Cowden Syndrome, an important heritable and multiorgan cancer syndrome, are not well defined. Proper diagnosis is essential for effective cancer surveillance and prevention in these patients. STUDY: Cowden patients with gastrointestinal polyps were selected for medical record and pathologic slide review...
