Olca Basturk, Gokce Askan
The pancreas is a complex organ that may give rise to large number of neoplasms and non-neoplastic lesions. This article focuses on benign neoplasms, such as serous neoplasms, and tumorlike (pseudotumoral) lesions that may be mistaken for neoplasm not only by clinicians and radiologists, but also by pathologists. The family of pancreatic pseudotumors, by a loosely defined conception of that term, includes a variety of lesions including heterotopia, hamartoma, and lipomatous pseudohypertrophy. Autoimmune pancreatitis and paraduodenal ("groove") pancreatitis may also lead to pseudotumor formation...

Sclerosing mesenteritis is primarily diagnosed through histologic and radiologic evaluation; however, only a few works provide a systematic description using MRI. This work presents the case of a 68-year-old male, who was admitted for a routine cholecystectomy. Intraoperativly, a large mass was identified dislocating the abdominal viscera. The microscopic examination revealed vascular congestion of the omentum. The contrast-enhanced CT and MRI scans revealed the presence of a heterogenous, lipomatous mass with lesions visible only in T2W and contrast-enhanced T1W MRI...

The classification of atypical adipocytic neoplasms with spindle cell features remains challenging. To better define this category of low-grade lipomatous neoplasms, we present herein the clinical, histologic, and immunohistochemical characteristics of a large series of 232 atypical spindle cell lipomatous tumors. The lesions affected 140 males and 92 females, at an average age of 54 years (range, 6 to 87 y), clinically presenting as a persistent or enlarging mass with a median size of 5 cm. The anatomic distribution of the tumors was wide, predominating in the limbs and limb girdles (147 cases, 63%), mainly in the hands and feet (17% and 11%, respectively), with equal distribution between subcutaneous and deeper locations...

Lipomatous meningiomas are a very rare form of brain meningiomas consisting of fat accumulation within the tumor. Magnetic resonance imaging (MRI) or computerized tomographic (CT) imaging can be utilized to visualize the fat accumulations, but histopathologic staining is necessary in order to make a definitive diagnosis. The key histopathologic feature is the identification of adipocyte-like cells within the tumor, but other markers have also been identified. In this case report and review of the literature, we discuss how to recognize the symptoms associated with lipomatous meningiomas and the definitive treatment approach for these rare tumors...

Spindle cell lipoma located in the dermis is uncommon. The plexiform variant of this tumor is rare. In fact, only six cases of this variant have been described previously. We report herein a case of dermal plexiform spindle cell lipoma with prominent myxoid matrix. A 47-year-old male patient presented with a solitary, 2.2 cm-cutaneous mass in the right buttock region that had slowly increased in size for over one year. The dermal lesion was characterized by a mixture of mature adipocytes, spindle shaped cells and inconspicuous ropey collagen bundles in a mucinous background...

We report a case of two peculiar gallbladder polyps in a sixty-four year old male who presented with symptomatic cholelithiasis. Cholecystectomy was performed, which revealed two polyps measuring 0.6 cm and 1.9 cm, located in the body of the gallbladder. Microscopic examination of the polyps showed composite mesenchymal lesions with vascular proliferation of small-to-medium sized arterioles, myoid stroma, and lipomatous periphery. The myoid component was characterized by wisps of bland smooth muscle fibers loosely separated by proteinaceous and focally myxoid matrix...

OBJECTIVES: Symptomatic angiomyolipoma (AML) and asymptomatic AML larger than 4 cm in size are usually treated with nephron-sparing surgery or transarterial embolization. We used radiofrequency ablation to treat the vascular pedicle of exophytic AML with low R.E.N.A.L. nephrometry score and investigated its feasibility for hilar off-clamping nephron-sparing surgery. METHODS: Contrast-enhanced computed tomography (CT) showed enhanced, well-defined lipomatous tumors with a maximum diameter of 4-8 cm in the kidney of 15 patients...

Sarcomas are a heterogeneous group of mesenchymal tumors arising from soft tissue or bone, with an uncertain etiology and difficult classification. Soft tissue sarcomas (STSs) account for around 1% of all adult cancers. Till date, more than 50 histologic subtypes have been identified. Adipocyte sarcoma or liposarcoma (LPS) is one of the most common STS subtypes, accounting for 15% of all sarcomas, with an incidence of 24% of all extremity STSs and 45% of all retroperitoneal STSs. The new World Health Organization classification system has divided LPS into four different subgroups: atypical lipomatous tumor/well-differentiated LPS, dedifferentiated LPS, myxoid LPS, and pleomorphic LPS...

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...

PURPOSE: The spinal epidural angiolipomas are rare expansive processes made of mature lipomatous and angiomatous elements. They often have a benign character. Their etiology, pathogenesis remains uncertain, and it is a cause of spinal cord compression. The magnetic resonance imaging is the most important neuroradiological examination. Histological examination is the only examination to confirm the diagnosis. Surgery is the treatment of choice. METHODS: A retrospective study of all patients operated on for a spinal epidural angiolipoma at the Department of Neurosurgery at the National Institute of Neurology of Tunis between January 2000 and December 2014 (15 years) was performed...

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...

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)...

CONTEXT: -Atypical lipomatous tumors/well-differentiated liposarcomas contain alterations in the 12q13-15 region resulting in amplification of MDM2 and nearby genes. Identifying MDM2 amplification is a useful ancillary test, as the histologic mimics of atypical lipomatous tumors/well-differentiated liposarcomas have consistently shown a lack of MDM2 amplification. OBJECTIVE: -To assess the interobserver reproducibility of a bright-field assay for MDM2 amplification (dual-color, dual-hapten in situ hybridization [DDISH]) among reviewers with varying degrees of experience with the assay and to assess the concordance of MDM2 DDISH with MDM2 fluorescence in situ hybridization (FISH)...

PURPOSE: Liposarcomas are the most common soft tissue sarcomas of adults. The identification of lipoblastic cells in soft tissue sarcomas is mandatory for the diagnosis of most subtypes of liposarcomas but may be difficult in conventional histology. The present study focuses on the expression and possible diagnostic impact of two PAT family proteins, perilipin 1/perilipin and perilipin 2/adipophilin in human liposarcomas. METHODS: Eighty-seven cases of liposarcomas and 30 cases of non-lipomatous sarcomas were investigated immunohistochemically for perilipin 1 and 2 using entire tissue sections...

Fibrous hamartoma of infancy (FHI) is a benign mesenchymal tumor histologically characterized by a mixture of intersecting fascicles of fibroblasts/myofibroblasts in collagenous stroma, nests of primitive oval or stellate cells in basophilic mucoid stroma, and mature adipose tissue. We hypothesized that FHI, because of histologic overlap with mesenchymal overgrowth tumors seen in CLOVES (Congenital Lipomatous Overgrowth with Vascular, Epidermal, Skeletal anomalies) and Proteus syndromes, may harbor mutations in signaling pathways associated with cellular proliferation...

Cardiac valve lipomatous hamartomas are very rare lesions with preferential localization on the pericardium, followed by the endocardial surfaces. We report a quite unique case of a lipomatous hamartoma-like lesion involving a bicuspid aortic valve. The lesion was incidentally found in a young patient undergoing cardiac surgery for aortic regurgitation, and the diagnosis was done by histology. It cannot be excluded that the lipomatous hamartoma-like lesion might have contributed to aortic valve regurgitation...
