Background. Parapharyngeal space is one of potential facial planes for neoplasms and infections and represents less than 1% of all head and neck tumours. Occurrence of the pleomorphic adenoma in the parapharyngeal space is a rarity. Case Presentation. Here, three giant pleomorphic adenomas of different sizes occupying the parapharyngeal space in three patients are reported. Extensive preoperati...

Purpose. Four further cases of desmoplastic small round cell tumour with multi phenotypic differentiation are described.Subjects. Two patients were typical (male, adolescent with peritoneal tumour and, in one case, liver metastases) and did not respond well to treatment. Two other patients showed less usual features (young, female with retroperitoneal disease, both with intraspinal extension an...

Four patients in terminal renal failure who had various malignant tumours were treated by haemodialysis and cadaveric renal transplantation. One patient with a testicular seminoma and one with leiomyosarcomatous changes in polycystic kidneys were successfully grafted after removal of the tumours and both were healthy at three and two-and-a-half years afterwards without evidence of recurrence of...

Tumours of the digestive system include a number malignant tumours such as oesophageal, gastric and colorectal cancers, which have highest incidence mortality rates in world. Their occurrence is related to variety factors, diet, environment genetics. As key enzyme process folate metabolism, MTHFR gene polymorphism plays an important role pathogenesis development gastrointestinal tumours. This p...

Medulloblastoma arises in the cerebellum and is the most common malignant brain tumour of childhood, however its molecular basis is not well understood. To assess the role of aberrant epigenetic events in medulloblastoma and identify critical genes in its development, we profiled the promoter methylation status of 11 candidate tumour-suppressor genes (TSGs; p14(ARF), p15(INK4b), p16(INK4a), CAS...

OBJECTIVES To report cases of primary neuroendocrine tumours (NETs) of the kidney, including carcinoid tumour, large cell neuroendocrine carcinoma (LCNEC) and small cell carcinoma (SCC), which show a wide range of NE differentiation and biological behaviour, and are exceedingly rare. PATIENTS AND METHODS The clinicopathological features of all nine renal NETs diagnosed during a 7-year period ...

introduction: due to the whole network of polyposis registers worldwide and early prophylactic treatment, survival of familial adenomatosis (fap) patients is improved. extracolonic manifestations are remarkable feature of fap. two extracolonic manifestations (duodenal adenomatosis, leading duodenal cancer and desmoid tumours) play a very important role in the reasons of death in polyposis popul...

Case Description-A four-year old Balami ram weighing 120kg was presented to the University of Maiduguri Veterinary Teaching Hospital (UMVTH) with extensive swelling and ulceration of the nictating membrane of the left eye. Clinical Findings-A dark red hard mass on the third eyelid was covering the entire eyeball. The visible mass measured 5cm vertically and 7cm horizontally. Pus exudate was exp...

A radioimmunoassay for neuron specific enolase (NSE), a marker of neuroendocrine differentiation, has been evaluated in small cell lung cancer (SCLC). In untreated patients 25/38 (68%) with localized SCLC had raised blood levels of NSE (>13 ng ml-1), in extensive disease 34/39 (87%) patients had raised NSE levels. In patients with non-small cell lung cancer (NSCLC) the serum levels were raised ...

BACKGROUND Primary tracheal tumours are rare, so few physicians have extensive experience of their management. No direct comparisons have been made of surgical and radiotherapy treatment. METHODS A postal survey of cases presenting in the last 10 years in the United Kingdom was conducted. Results were expressed as cumulative survival and survival curves were compared by the log rank test. R...
