Soft tissue perineuriomas are an unusual type of peripheral nerve sheath tumors distinct from schwannomas and neurofibromas, with interesting histologic findings. They are not well characterized on radiographic examination. We report this case of a patient with sinonasal perineurioma to help define the imaging and pathologic features of this rare head and neck tumor.

We investigated an acute outbreak of the cutaneous form of fowlpox among chickens in China in November 2009. Using pathologic and virologic methods, we identified a novel type of fowlpox virus that carried an integrated genomic sequence of reticuloendotheliosis virus. This highly pathogenic virus could lead to severe ecologic effects and economic losses.

Background Ischemic colitis is frequent disease in the elderly population. Early medical or surgical treatment is the key factor for a favourable prognosis. Many clinical, biohumoral and pathologic factors had been considered to indicate better treatment. "Severity" of the disease seems a prognostic factor for surgery. Aim of this study is to identified objective factors predictive of the bette...

We describe the clinical presentation, course and pathologic findings found in three adult patients with lipid storage myopathy. Excessive lipid storage was found in Type 1 fibers of muscle. Clinical improvement on oral levo-carnitine therapy suggests the possibility of carnitine deficiency as the most likely etiology in two of the patients and one had mitochondrial myopathy confirmed on geneti...

introdouction: the aim of this study was to determine the associations between commonly found pathologic conditions and angulation of the lower third molar teeth. materials and methods: in this retrospective study, 370 panoramic radiographs consisting of 724 lower third molars were evaluated for any pathologies according to their angulation(mesioangular, distoangular, vertical, or horizontal). ...

abstract background: esophageal cancer is one of the major malignancies, with various epidemiological aspects in recent years in developing countries, including increased prevalence and variations of pathologic patterns. this may be due to increasing rates of barrett’s esophagus, gastroesophageal reflux, smoking and obesity. this study was performed from 1991 to 2005 in order to evaluate variou...

This case report contains clinical and pathologic features of a degenerative myelopathy in Holstein X Gir crossbred calves in Brazil. The bilateral and symmetrical spinal cord white matter lesions were interpreted as a primary axonopathy that may be of the dying-back type.

Dementia developed in a patient with widespread neurologic manifestations; she died within 5 months. Pathologic findings showed granulomatous inflammation with caseation necrosis, foreign body-type giant cells, and proliferative endarteritis with vascular occlusions. Broad-range polymerase chain reaction identified Mycobacterium neoaurum as the possible pathogen. Central nervous system infectio...

Cystic nephroma is a rare renal neoplasm which is usually benign histologically. We report a case of a 42-year-old woman with cystic nephroma arising from the lower pole of the right kidney with microscopic foci of sarcomatous stroma. Preoperative sonogram and CT scan were performed. Pathologic study revealed a cystic nephroma with foci of primitive, mesenchymal, undifferentiated, embryonal typ...

As the population ages, adult-onset neurodegenerative disorders will be encountered even more frequently by clinical neurologists. New treatments will continue to emerge as scientific understanding of the molecular genetic and pathophysiologic basis of these disorders evolves. Volume 8 of the Hospital Physician Neurology Board Review Manual will focus on the diagnosis and management of neurodeg...
