Sparganum is the larvae of a parasite called Spirometra. It usually lives in snakes or frogs, which are parasitic on the human who consume them raw. Sparganum is presented with a form of mobile subcutaneous nodule in various parts of human body. A 78 years old man with palpable neck mass visited our clinics. He had a history of eating snakes raw about 50 years ago. He was diagnosed with Sparganosis through a fine needle aspiration biopsy and underwent excisional biopsy. Sparganosis should be considered when dealing subcutaneous palpable neck mass with history of consuming raw snakes or frogs.

Myoepithelioma is a rare benign neoplasm that mostly arises in the major salivary glands and sometimes in the minor salivary glands, which account only for less than 1% of all salivary glands neoplasms. However, its extra-salivary involvement is even rarer and only a few cases of nasal cavity myoepithelioma were reported in the English-language literature so far. In this case report, we present a 40-year-old female with unilateral nasal obstruction diagnosed as myoepithelioma of the nasal septum and treated with endoscopic sinus surgery.

Killian-Jamieson and Zenker diverticula are both rare pharyngoesophageal diverticula. Both are outpouching of the mucosal and submucosal layers of the esophageal wall, which protrude through a mucosal gap at the level of the pharyngoesophageal esophagus. When these diverticula are large enough, they can be in proximity to the thyroid gland and may mimic a thyroid nodule. We report a case in which a diverticulum was filled with dietary residue and thus simulated a thyroid cyst on CT scan. And it was finally diagnosed as a Killian-Jamieson diverticulum by the surgery.

Malignant schwannoma is a rare tumor arising from the schwann sheath of the nerve fibers. It spreads early to reginal node and metastasis to the lung. Radical surgery have performed for treatment of choice but combined modalities such as radiotherapy or adjuvant chemotherapy have been recommanded recently. The authors experienced two cases of malignant schwannoma originating from the ethmoid sinus and ventricular fold of larynx. and we report these cases briefly.

Myoepithelioma is composed predominantly or exclusively of myoepithelial cells. It is most frequently located in parotid gland, the palate and the breasts. It accounts for less than l% of all salivary gland tumors. Surgical excision which accompany a marginal amount of uninvolved tissue is curative. We report a case of parotid gland myoepithelioma treated by surgery.

Low-grade fibromyxoid sarcoma (LGFMS), a soft tissue tumor that has high recurrence and metastasizing potential, rarely occurs in the head and neck region. Therefore, the treatment for LGFMS in the facial area is challenging in terms of cosmetic and functional maintenance. The authors report a case of LGFMS in the posterior nasal cavity. It was completely removed in parallel with the nasal endoscopic and oral approach, but the lower margin was closed by preserving the soft palate. The patient is well without any recurrence or metastasis after 5 years of follow-up.

Myofibroblastic sarcoma can be classified as low-, intermediate-, and high-grade. Low-grade myofibroblastic sarcoma (LGMS) is uncommon and rarely appears on the skin. LGMS is diagnosed based on histopathological and immunohistochemical findings. Additionally, LGMS metastases are rare as well. Herein, the authors describe a case of cutaneous LGMS in the neck. To the best of our knowledge, there are no cases regarding cutaneous LGMS in the neck present in the existing literature. Surgical resection is considered as the most important treatment for LGMS. Therefore, a complete tumor resection was performed in this case. However, another mass in the uterus was identified on abdominal computed tomography performed post-surgery.

Background and Objectives : Narrow Band Imaging(NBI) is a novel optical technique that enhances the visualization of superficial microvascular architecture which is commonly increased and founded as an irregular shape in a neoplastic lesion. The aim of this study is the evaluation of the usefulness of NBI in the diagnosis of Head and Neck Cancer. Subjects and Methods : From December 2009 to January 2011, 31 consecutive patients who were diagnosed with head and neck malignancy were enrolled in this prospective study. The malignant findings of NBI were demarcated brownish lesion or increased intraepithelial papillary capillary loops(IPCLs) with or without irregularity. Results : There were 29 cases(93.5%) of well demarcated brownish lesion, 26 cases(83.9%) of increased IPCLs and 4 cases(12.9%) of satellite lesions. Diagnostic accuracy of endoscopic examination was increased from 83.9% to 93.5%, when NBI was applied to the conventional endoscopy(p>0.05). Conclusion : NBI is a powerful and safe screening test, which can be performed in out patient clinic without any supplementary procedure.

Background and Objectives: The popularity of complementary and alternative medicine(CAM) has grown at an astonishing rate in recent years. Because patients are interested in CAM and want to use it, physicians also should be concerned about CAM and know about the current situation of its usage. In this study, we tried to determine the prevalence of CAM use in the patients with head and neck cancer and correlate with demographics and tumor characteristics. Materials and Methods: A total of 87 patients with head and neck cancer previously treated with surgery at Seoul National University Hospital from March through June, 2004 were enrolled in this study. The patients were completed, questionnaire about the use of CAM and demographic information. Tumor characteristics were obtained from the patient's medical records. Results: Of the 87 patients, 33 patients(37.9%) use at least one CAM. There was no statistically significant correlation between patient's data and prevalence of CAM use. Of those patients using CAM, 16(48.5%) of 33 were using 2 or more therapies. The majority of agents used by patients in this study are mushrooms such as Phellinus and Reishi, followed by dietary therapy. A majority(60.6%) of patients were introduced to alternative medicine by friends or family members. Conclusion: Considerable cancer patients use CAM. Head and neck oncologists should inform themselves about CAM to counsel and educate the patients. Further scientific investigations on promising CAM agents may help advance cancer treatment.

Objectives: The authors tried to analyze the results of carotid artery sacrifice with or without preoperative carotid evaluation. Materials and Methods: Thirteen patients undergone carotid sacrifice were evaluated. Carotid balloon occlusion test (BOT) and single-photon emission computed tomography (SPECT) with technetium-99m-labeled hexamethylpropyleneamineoxime ($^{99m}Tc-HMPAO$) were used for preoperative carotid evaluation. Results: The causes of carotid artery sacrifice consisted of the neck mass involving the carotid artery, spontaneous aneurysmal rupture, and traumatic pseudoaneurysm. Five patient had postoperative neurologic complications and two of them had permanent neurologic deficits. Conclusion: The authors stress that the preoperative evaluation in carotid artery sacrifice is imperable, and the BOT with SPECT can be used in selecting the method of treatment. But since these tests cannot predict the postoperative outcome perfectly, careful perioperative care of the patients should be exercised regardless of the results of the preoperative evaluation.
