Objective: Benign subcutaneous lipomas can cause musculoskeletal pain and nerve impingement. We hypothesized that the potent lipolytic and atrophic effect of 40mg/mL triamcinolone acetonide would atrophy symptomatic lipomas so surgical excision could be avoided. Design: This was a cohort study. Setting: This study took place in an ultrasound injection clinic. Participants: Eight subjects with painful symptomatic lipoma were included. Measurements: Preprocedurally, the margins of the lipomas were palpated and marked with ink, then measured in centimeters (cm)...

REVIEW
J M Lieb, F J Ahlhelm
CLINICAL ISSUE: Agenesis of the corpus callosum is reported to have an incidence of about 1:4000 live births. In 30-45% of cases, genetic etiologies can be identified, e. g., 10% chromosomal anomalies and 20-35% genetic syndromes. Environmental factors like fetal alcohol syndrome are also known to be prone to callosal agenesis. Callosal agenesis can be complete or partial and can be isolated or associated with other central nervous system (CNS) anomalies (e. g., cortical developmental disorders, callosal lipoma, intracranial cysts) or extra-CNS anomalies (e...

Lipoma is a very common soft tissue neoplasm, but only infrequently found in the oral region. Intramuscular lipoma (IML) is a relatively common variant of lipoma. The most common site for IML is the large muscles of the extremities, and it is quite rare in the oral cavity. A case of IML affecting the floor of the mouth/tongue of a 42-year-old female is described. The patient presented with a 4 cm diameter yellow mass in the right side of the sublingual area. Axial and coronal magnetic resonance imaging demonstrated its infiltrating nature that can be distinguished from the ordinary well-encapsulated lesion...

Introduction: Extremity lipomas and well-differentiated liposarcomas (WDLs) are difficult to distinguish on MR imaging. We sought to evaluate the accuracy of MRI interpretation using MDM2 amplification, via fluorescence in-situ hybridization (FISH), as the gold standard for pathologic diagnosis. Furthermore, we aimed to investigate the utility of a diagnostic formula proposed in the literature. Methods: We retrospectively collected 49 patients with lipomas or WDLs utilizing MDM2 for pathologic diagnosis...

Traumatized lipomas with degenerative change may demonstrate histopathologic features that mimic atypical lipomatous tumor (ALT). Previously reported series of ALT involving the oral cavity preceded routine use of MDM2 and CDK4 immunohistochemistry. Our aim is to evaluate MDM2 and CDK4 immunohistochemical expression in adipocytic tumors arising in this site, in conjunction with the histiocytic marker PU.1, to determine whether MDM2 and CDK4 impacts classification. 17 cases originally diagnosed as ALT were retrieved and immunohistochemical studies for MDM2, CDK4 and PU...

OBJECTIVE: This study aims to compare ultrasonography for ventral hernias with surgical findings and establish its accuracy in equivocal cases. Comparison is also made against groin hernia ultrasound scanning, which has a positive predictive value ranging from 71-100%. METHODS: A retrospective review of all patients who underwent an ultrasound scan between June 2011 and June 2015 was performed. The word 'hernia' in the referral information was the sole inclusion criterion...

Parosteal lipoma derived from the rib is extremely rare and is usually resected through open thoracotomy despite its benign nature. A 33-year-old man who had no symptoms was referred to our hospital for treatment of a 30-mm chest wall mass that has slightly increased in size during 2 years of follow-up. En bloc resection of the tumor with parts of the 3rd and 4th ribs was performed through a complete thoracoscopic approach using orthopedic electric micro drill. This was the first report on a case of parosteal lipoma of the rib that was resected by a complete thoracoscopic procedure...

Pancreatic masses consisting of lipomatous components clinically include lipoma, liposarcoma, lipomatous pseudohypertrophy of the pancreas, fat-containing neoplasms such as perivascular epithelioid cell tumor, and malignant neoplasm with lipoid degeneration. We present pancreatic lipomatous hamartoma, which has not been reported hitherto. A solid pancreatic mass was detected from a computed tomographic scan check-up in each of 3 cases of Japanese men. Macroscopically, well-demarcated solid lipomatous masses were detected at the uncus, body, and tail of the pancreas, respectively...

This report shows a multi-compartmental lipoma that occupied a vast area of the hand volar compartment, the distal aspect of the Parona's space and infiltrated the dorsal compartment between the IV and V metacarpal bones. The mass was entirely removed through a dorsal approach, minimizing risks of neurovascular and tendinous lesions.

Herein, we report a large lipoma at the spinoglenoid notch that mimicked a rotator cuff tear, which occurred in a 61-year-old male farmer. Weakness and pain in the shoulder started abruptly after hard labor, and our first impression was a traumatic rotator cuff tear; however, there was no tear on MRI, and complete marginal excision of a large lipoma at the spinoglenoid notch relieved the symptoms completely at a postoperative three-month follow-up visit. We believe that certain activities such as forceful shoulder abduction may have caused the sudden onset of suprascapular neuropathy in the loosely compressed suprascapular nerve by the lipoma...

INTRODUCTION: Lipomas are the most common benign mesenchymal tumors which can be found in any part of the body. Nevertheless, their etiology and pathogenesis remain unknown. It is hypothesized that some of these lesions could result from an acute or chronic trauma. PATIENTS AND METHODS: We report a case of a 54-year-old man presenting a perineal lipoma which volume grew rapidly after he fell on his buttock, in the context of inaugural epileptic seizure. Pelvic MRI showed a voluminous fatty mass, measuring 6...

Carpal tunnel syndrome can be the result of a wide variety of etiologic factors. Compressive causes are rare and tumors causing compression are even rarer. We present a case with a carpal tunnel syndrome caused by an intraneural lipoma and an arteriovenous malformation concomitantly. The lesions were excised, and the patient recovered with full hand function and entire disappearance of acroparesthesia. To our knowledge, this is the first case report of carpal tunnel syndrome caused by an intraneural lipoma and an arteriovenous malformation concomitantly...

INTRODUCTION: Currarino's syndrome (CS) is an autosomal dominant disorder of embryonic development causing a rare malformating syndrome characterized by a triad of an anorectal malformations, presacral mass (most commonly an anterior sacral meningocele) and sacral bony defects. Mutations of the HLXB9 gene have been identified in most CS cases, but a precise genotype-phenotype correlation has not been described so far. Family screening is obligatory. The diagnosis is usually made during childhood and rarely in adulthood...

INTRODUCTION: Hibernoma is a very rare benign tumor that arises from vestigial remnants of fetal brown adipose cells and usually manifests as a slowly growing, painless soft-tissue mass. It mainly occurs in adults, in the third and fourth decade of life, slightly more in women and is commonly seen in the subcutaneous regions of the back, neck, thighs and retroperitoneum. It was originally described in 1906 by Merkel, who named it "pseudolipoma". In 1914, Gery derived the name hibernoma from the tumor's histological similarity to brown fat in hibernating animals...

BACKGROUND: Spindle cell/pleomorphic lipomas are benign tumors. Here, we present our cytogenetic data on 31 such tumors. MATERIALS AND METHODS: G-banding chromosome analysis and (in selected cases) fluorescence in situ hybridization (FISH) using probes for FOXO1, RB1, and HMGA2 were performed. RESULTS: Rearrangements of chromosome 13 were found in 58% of tumors. Chromosomes 6, 1, 12, and 11 were also involved in 42%, 26%, 26%, and 23% of tumors, respectively...

Aggressive angiomyxoma (AAM) is an uncommon mesenchymal tumor that predominantly involves the pelvis and perineum of young females. It is often clinically mistaken for more common superficial lesions such as vaginal cysts, labial cysts, and lipomas. A review of the medical literature reveals very few cases of AAM reported in pregnancy. We describe a rare case of AAM in pregnancy, clinically misdiagnosed as prolapsed cervical fibroid.

Intracranial lipomas are rare incidental lesions. Rokitansky first described a corpus callosal lipoma on the posterior part of the corpus callosum in 1856. Since then many cases have been reported. We report the imaging findings of an interhemispheric lipoma extending into subcutaneous plane associated with spinal lipomeningocele and corpus callosal dysgenesis. Computed tomography and magnetic resonance imaging findings are characteristic. All cases have been reported in pediatric age group till now. Such a case in this age group has not been reported earlier...
