nasopharyngeal angiofibroma is a relatively uncommon vascular tumor affecting adolescent males and it characteristically originates in the posterior lateral wall of the nasopharynx. primary extra-nasopharyngeal angiofibroma is very rare. here, i present a case of angiofibroma of the parapharyngeal space in a 53-year-old woman with ct and sonographic findings.

background esophageal, stomach, and colorectal cancers are commonly lethal gastrointestinal tract (git) neoplasms, causing almost two million deaths worldwide each year. some environmental risk factors are acknowledged; however, genetic defects can significantly contribute to predisposition to git cancers. accordingly, recent works have shown that single-nucleotide polymorphisms (snps) within m...

Nasopharyngeal carcinoma (NPC) is common among southern Chinese including the ethnic Cantonese population living in Hong Kong. Epstein-Barr virus (EBV) infection is detected in all undifferentiated type of NPC in this endemic region. Establishment of stable and latent EBV infection in premalignant nasopharyngeal epithelial cells is an early event in NPC development and may contribute to its pat...

In this study, we aimed to use the combined detection of multiple antibodies against Epstein-Barr virus (EBV) antigens to develop a model for screening and diagnosis of nasopharyngeal carcinoma (NPC). Samples of 300 nasopharyngeal carcinoma patients and 494 controls, including 294 healthy subjects (HC), 99 non-nasopharyngeal carcinoma cancer patients (NNPC), and 101 patients with benign nasopha...

BACKGROUND & OBJECTIVE Nasopharyngeal necrosis is an unusual sequelae after radiotherapy for nasopharyngeal carcinoma (NPC). It is mostly managed by conservative treatment, but the efficacy is unsatisfied. This study was to investigate the efficacy of endoscopy-guided debridement on irradiation-related nasopharyngeal necrosis in NPC patients after radiotherapy. METHODS Between Jul. 2006 and M...

introduction:most metastatic lymph nodes from head and neck malignancy are solid. cystic nodes are found in 33% - 61% of carcinomas arise from waldeyer’s ring, of which only 1.8% - 8% originate are from the nasopharynx. some cystic cervical metastases were initially presumed to be branchial cleft cyst. this case report aims to highlight the unusual presentation of cystic cervical metastasis sec...

introduction: nasopharyngeal carcinoma (npc) is a common cancer in the north-east region of india. though the role of environmental contributors of npc in the north-eastern part of india is firmly established, ebv as an etiological agent in the region remains unexplored. material and methods: fifty-one patients, who presented at the department of ent, neigrihms and were confirmed as npc upon hi...

introduction radiotherapy is regarded as the first treatment of choice for nasopharyngeal carcinoma. despite the advantages of radiotherapy, patients may suffer from a wide range of side-effects due to the presence of many sensitive normal tissues in these regions. if the absorbed dose exceeds the tolerance level in parotid glands and the spinal cord, myelopathy, lhermitte's sign and xeros...

Background & objective:Primary pleural neoplasms are rare entities compared with the pleural involvement by metastatic carcinoma. The current study aimed at investigating the complete spectrum of pleural neoplasms and differentiating between them with the aid of immunohistochemistry (IHC). Methods: Consecutive pleu...
