BACKGROUND: Solitary fibrous tumors (SFTs) are rare mesenchymal tumors commonly located in the pleura, soft tissues, or meninges and are characterized by the NGFI-A-binding protein 2 (NAB2)-signal transducer and activator of transcription 6 (STAT6) fusion gene. Recent studies have indicated that nuclear STAT6 immunohistochemistry is a specific marker for SFTs. METHODS: The authors reviewed fine-needle aspiration (FNA) specimens from extracranial SFTs diagnosed at their institution between 1993 and 2017...

Lipoma is the most common benign mesenchymal neoplasm. About 16% of lipomas arise in the head and neck region, especially in the posterior neck. Large lipomas that originate from the retropharyngeal space may cause dyspnea, dysphagia, and snoring and occasionally may lead to obstructive sleep apnea syndrome (OSAS). Herein, we report a 45-year-old male patient with OSAS caused by a giant retropharyngeal lipoma with emphasis on CT findings.

A 66-year-old man was referred to our hospital with an increasing subepithelial lesion in the gastric antrum. Using esophagogastroduodenoscopy, a tumor with a steep, 20-mm-high rise protruding in the lumen was observed. The mucosal surface of the tumor was reddish, with ulcers forming at the base. Moreover, the tumor was mobile and soft. A biopsy specimen was taken from the ulcer, but tumor tissue was not collected from the submucosa. Endoscopic ultrasonography (EUS) showed a high echoic mass in the submucosa...

INTRODUCTION: Intestinal Lipomatosis consists of diffuse lipomas in various regions from the small to large bowel. They can remain asymptomatic or present with complications such as Intussusception. DISCUSSION: Intestinal lipomatosis complicated by Intussusception is a rare occurrence that has not been well documented. Rare condition management is difficult to approach because of the customizability each scenario requires. We hope through sharing our approach this can serve as a rough template to physicians who find themselves in a similar scenario...

INTRODUCTION: Duodenal lipoma is very rare with limited case reports present in literature. Owing to recent advances in endoscopy and modern imaging techniques, more cases are being diagnosed and treated. However, no systematic study of duodenal lipomas has been reported. AIM: To study the diagnosis and treatment of duodenal lipoma in a female patient and review the relative literatures to enhance the knowledge of it. MATERIALS AND METHODS: A literature search for 'duodenal lipoma' was performed on PubMed...

Z Zhu, Y Chai
Omental herniation through a diaphragmatic defect without involvement of the stomach is rare and has often been misdiagnosed as mediastinal lipoma. We herein report two cases of intrathoracic omental herniation through adiaphragmatic defect in patients that were misdiagnosed as a mediastinal lipoma at presentation. They both underwent successful laparoscopic diaphragmatic hernia repairs with full resolution of their symptoms. Doctors should pay attention to the differential diagnosis between diaphragmatic hernia and mediastinal lipoma when a fatty mass is found in the mediastinum at the magnetic resonance imaging (MRI) or computed tomography (CT) scan...

A hitherto unreported case is presented wherein a 2year old child had a 'cranial lipomeningocoel' or a 'nasal lipo-encephalocoel'. The child presented with a growing mass in the base of the nose. Investigations revealed that the nasal mass was a lipoma that was an extension of intracranial lipoma. The intracranial component extended up to corpus callosum. Resection of the extracranial extension and basal reconstruction resulted in cosmetic recovery.

Spindle cell/pleomorphic lipomas (SCLs), cellular angiofibromas (CAFs) and mammary-type myofibroblastomas (MFBs) are rare benign mesenchymal tumors with monoallelic 13q14 deletion. They are predicted to have a common pathogenic mechanism due to shared similar histological and immunohistochemical features; however, pathological consequences of monoallelic 13q14 deletion remain unknown. We previously reported a CAF case with monoallelic 13q14 deletion in which the tumor expressed decreased levels of FOXO1 and RB1, both of which were encoded in 13q14, and increased reactive oxygen species (ROS) levels...

RATIONALE: A hyperlordosis deformity of the lumbar spine is relatively rare, and surgical treatment has not been comprehensively addressed. In this case report, we describe the clinical presentation, surgical treatment, and medium-term follow-up of a patient presenting with a progressive lumbar hyperlordosis deformity after resection of a spinal lipoma associated with spina bifida. PATIENT CONCERNS: The patient was a 20-year-old woman presenting with a progressive hyperlordosis deformity of the lumbar spine associated with significant back pain (visual analog pain score of 89/100 mm), but with no neurological symptoms...

Lipomas are benign adipose masses that are rarely associated with synovial membranes. In addition, there are only a few reports describing synovial lipomas in the foot. No reported occurrence of this lesion in the subtalar joint currently exists. This case report documents the presentation, clinical evaluation, advanced imaging, and surgical management of a 45-year-old man with a large synovial lipoma of the subtalar joint.

BACKGROUND: Homozygous mutations and deletions of the microcephalin gene (MCPH1; OMIM *607117) have been identified as a cause of autosomal recessive primary microcephaly and intellectual disability (MIM #251200). Previous studies in families of Asian descent suggest that the severity of the phenotype may vary based on the extent of the genomic alteration. We report chromosome microarray (CMA) findings and the first described family study of a patient with primary microcephaly in a consanguineous Hispanic family...

The classification of the until recently poorly explored group of atypical adipocytic neoplasms with spindle cell features, for which recently the term atypical spindle cell lipomatous tumor (ASLT) has been proposed, remains challenging. Recent studies have proposed ASLT as a unique entity with (in at least a significant subset of cases) a specific genetic background, namely deletions/losses of 13q14, including RB1 and its flanking genes RCBTB2, DLEU1, and ITM2B. Similar genetic aberrations have been reported in pleomorphic liposarcomas (PLSs)...

Lipoma is a relatively common benign tumour occurring at sites of the body which are rich in adipose tissue. Due to sparsity of adipose tissue within the oral cavity, lipoma rarely presents in this region. Fibrolipoma of the tongue is a rare lesion. There are only 14 cases reported in the literature. An 85-year-old patient presented with a painless mass on the tongue interfering with eating. There were no risk factors for malignancy and no family history of malignant diseases. Although intraoperatively the lesion was locally infiltrative, histopathology revealed a rare benign fibrolipoma...

INTRODUCTION: The incidental early-stage thymic mass presents a diagnostic challenge. Video-assisted thoracoscopic (VAT) thymectomy is an attractive but potentially morbid solution. The aim was to show it can be safely applied as a first-line modality in those with undiagnosed thymic enlargement with acceptable long-term results. METHODS: A total of 45 patients were identified (24 male, median age 52 interquartile range [IQR]: 41-66 years) in a 14-year experience who had CT evidence of an enlarged, possibly malignant thymic mass, but no tissue diagnosis before undertaking VAT thymectomy...

INTRODUCTION: The identification of subepithelial lesions is a relatively frequent finding at endoscopy however their natural history is not well known. Our aim was to analyze the role of endoscopic ultrasound (EUS) in the diagnostic approach of subepithelial lesions of the upper gastrointestinal tract. METHODS: Retrospective study which included 324 patients undergoing upper radial EUS for evaluation of subepithelial lesions from 2008 to 2014. The EUS features, presumptive diagnosis and management decision were analyzed...
