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...

CONTEXT The natural history of incidental branch-duct intraductal papillary mucinous neoplasm of the pancreas is still unknown. CASE REPORT The case of a 74-year-old man who had been diagnosed 14 years previously with an incidental branch-duct intraductal papillary mucinous neoplasm of the pancreatic head, 30 mm in size, without mural nodules and dilatation of the main pancreatic duct is here...

The present study aimed to evaluate the Fine Needle Aspiration Biopsy in different staining techniques in nodular lesions of the oral cavity and head and neck region, as their sensitivity, specificity and accuracy, staining with Panoptic, Papanicolaou and Hematoxylin-Eosin (H&E) stains. 46 patients who sought the Clinic of the Discipline of Clinical Stomatology at FOUSP were selected consecutiv...

BACKGROUND Synchronous primary neoplasms have been encountered in some patients with mucosal squamous cell carcinoma of the head and neck. Routine panendoscopy along with various radiological tests have been advocated to identify these potential tumors. In 1993, we originally described symptom-directed, selective endoscopy as an efficient and cost-effective means to evaluate patients to identif...

Inflammatory myofibroblastic tumors (IMT) in the head and neck region are rare neoplasms that generally mimic benign/low-grade neoplasms. Overexpression of anaplastic lymphoma kinase (ALK) has been reported in 50% of IMT cases, secondary to ALK activation by structural rearrangements in the ALK gene, which results in a fusion protein with echinoderm microtubule associated protein like 4 (EML4) ...

Reprint requests to: Dr. Yu-Chang Lee Department of Radiology E-Da Hospital/I-Shou University. No.1, Yi Da Road, Jiau-shu Tsuen, Yan-Chau, Kaohsiung 824, Taiwan, R.O.C. Schwannomas are common neoplasms in the head and neck region, but of these tumors only less than 4% was found in sinonasal location in the reported literature. Most of the reported cases are found in the maxillary or ethmoid sin...

OBJECTIVE The purpose of this study was to determine the diagnostic accuracy of using the retromandibular vein as seen on cross-sectional imaging to help differentiate superficial lobe from deep lobe tumors. METHODS Of the patients who had parotid neoplasms between January 1997 and July 2002, we were able to identify 44 patients with preoperative imaging studies that were available for evalua...

Lipoblastomas are benign neoplasms of white adipose which usually occupy the trunk and limbs in pediatric patients. They can seldomly involve head neck, as a lateral cervical mass. Magnetic resonance imaging is most useful modality for identifying these lesions. Treatment involves complete excision, patients followed with serial exams and/or recurrence more common neck. Here we present an excee...

Introduction: The large defects resulting from head and neck tumour surgeries present a reconstructive challenge to surgeons. Although numerous methods can be used, they all have their own limitations. In this paper, we our experience with cervicofacial/cervicothoracic rotation flaps help expand the awareness application of flap. Case report: patient who underwent repair flap in department has ...

introduction: desmoid tumors are very rare, benign fibrous neoplasms arise from the musculoaponeurotic structures throughout the body.   case report: the patient was a   seven-year old boy with a large mandibular mass growing over a period of six months. his ct-scan showed a large mass, 13 cm in diameter in the cheek area extending to the neck and trachea. biopsy was compatible with desmoid fib...
