Purpose: To compare the effects of gallium-67 (Ga-67) scintigraphy with computerized tomography (CT) scanning in the diagnosis of head and neck neoplasm. Materials and Methods: Eighty-three patients with neoplasm in head and neck underwent local CT scanning and Ga-67 scintigraphy preoperatively. The results were verified pathologically after operation. Results: In total 43 cases of benign neopl...

Lipoma is the most common benign mesenchymal neoplasm. About 16% of lipomas arise in the head and neck region, especially in the posterior neck. Large lipomas that originate from the retropharyngeal space may cause dyspnea, dysphagia, and snoring and occasionally may lead to obstructive sleep apnea syndrome (OSAS). Herein, we report a 45-year-old male patient with OSAS caused by a giant retroph...

The pancreatic head and neck constitute less than half (mean 46 +/- 5%) of the whole pancreas. There is no difference in the concentration of ductal epithelium between the head and the body of the pancreas. The preponderance of pancreatic exocrine tumours which arise in the head of the pancreas compared to the body is not, therefore, due to a larger number of cells at risk in the pancreatic hea...

Introduction: The geographical distribution of head and neck cancer shows considerable variation and it is site dependent. The review of the literature shows few data concerning the head and neck cancer patterns in Iran. The purpose of this study was to represent epidemiological aspects of head and neck cancers in south east of Iran. Materials &Methods: In this retrospective study, from a to...

introduction: the pericranial flaps' benefits have been described in many otolaryngologic, maxillofacial and plastic surgery literature. the benefits ar e due to the pericranial flaps unique characteristics including good flexibility and mobility, very rich blood supply from several arterial sources and access to sufficient bulk of the flap without any need for distant surgical sites. usin...

OBJECTIVE To measure setup error of head and neck neoplasm in radiotherapy and discuss over effects of error on physical dose acting on target region and organs at risk of nasopharynx cancer (NPC) patients treated with intensity modulated radiation therapy (IMRT). METHODS A total of 152 patients who developed head and neck neoplasm and received IMRT were randomly selected. Through comparing d...

The consists of differentiated fusiform cells. frequency occurrence VMO among primary lung neoplasms up 1%. This type the most common tumors in children. can occur both childhood and adulthood. found soft tissues abdominal cavity, pelvic organs...

OBJECTIVE To examine the temporal changes in head and neck cancer in young adults in the United States. METHODS Using the cancer surveillance database from the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) Program, we calculated age-adjusted incidence rates for head and neck cancers. Using the joinpoint regression model, we described tongue cancer incidence tren...
