The cellularity of normal and lipomatous adipose tissue and its response to different lipolytic agents have been studied in a group of 10 patients with multiple symmetric lipomatosis (MSL). In MSL patients, fat cells from lipomatous tissue are smaller than normal, uninvolved adipocytes. Fat cells from lipomata show minimal variations in size following conspicuous increase of lipomatous masses. ...

First described by Bechtel and collaborators1, cerebellar liponeurocytomas are posterior fossa lesions composed of densely packed neuronal cells admixed with foci of welldifferentiated adipocyte-like cells. Similar tumors have also been referred to as lipomatous medulloblastoma, lipidized medulloblastoma, medullocytoma, neurolipocytoma, lipomatous glioneurocytoma, or lipidized mature neuroectod...

Cerebellar liponeurocytoma (LPN) is a rare central nervous system tumor. We encountered a 45-year-old woman with cerebellar LPN who had a three months history of headaches and mild ataxia. MRI revealed a mixed signal tumor in the cerebellar vermis. The tumor was totally removed. Histologically, a highly cellular neoplasm composed of monomorphic small round neuronal cells mixed with lipomatous c...

CONTEXT This report describes a minute pancreatic ductal adenocarcinoma which appeared to be in early stage tumor progression based on the study of its molecular abnormalities. In addition, it was associated with lipomatous pseudohypertrophy, a rare disease. CASE REPORT A 78-year-old male presented to our department with an incidental pancreatic tumor. Abdominal dynamic computed tomography sh...

primary malignant neoplasms of the pericardium are rare and are predominantly mesotheliomas, followed by benign localized fibrous mesothelioma, malignant fibrosarcoma, angiosarcoma and benign and malignant teratomas. 1 this article concerns an atypical presentation of this malignant tumor with symptoms and signs of pericardial effusion. this unusual feature was complete encasement of the heart ...

Introduction: Most common glioma tumors are tumors of the central nervous system (CNS) which are the cause of about 40 to 50 percent of brain tumors. This type of cancer includes 2 to 3 percent of cancers in the world. Conventional MRI is powerless in the detection and differentiation of benign and malignant tumors. In this case, diffusion weighted imaging (DWI) can create cont...

introduction: few studies on benign soft tissue tumors of oral cavity have been conducted in an iranian population. the purpose of this study was to evaluate the prevalence of the benign soft tissue tumors of the oral cavity in three central pathology centers of rasht, iran. materials and methods: in this retrospective study, all benign soft tissue tumors of the oral cavity, were retrieved from...

Sialolipoma is a rare benign neoplasm characterized by a well-circumscribed mass composed of neoplastic mature adipose tissue and non-neoplastic salivary gland elements. A 72-year-old woman presented with a painless swelling located in the hard palate, which had been identified 15 days earlier. Microscopically, the tumor was well-circumscribed consisting of lobular proliferation of the lipomato...
