Chondrosarcomas are uncommon tumors. Approximately 5-10% are located in the head and neck. Nasal septal chondrosarcoma is exceedingly rare, with an extensive review of the world literature revealing only 50 reported cases. Most occur in middle-aged man. Surgical resection is the definitive treatment of choice. Radiation and chemotherapy are reserved for residual or recurrent diseases and palliation. We present a case of nasal septal chondrosarcoma treated with craniofacial resection and postoperative radiation therapy.

Ewing sarcoma is a rare tumor in head and neck area. We demonstrate a rare case of sinonasal Ewing sarcoma initially suspected as olfactory neuroblastoma. After the surgery and immunohistochemical studies, it was accurately diagnosed as Ewing sarcoma. We would like to emphasize the possibility that Ewing sarcoma may originate from the head and neck area, and hence, it is important to use appropriate techniques for accurate diagnosis and treatment.

Pilomatricoma is a benign neoplasm of the hair follicle origin which most common occur in the head and neck, particularly in the cheek and preauricular region. This neoplasm is superficially located and stony, hard consistency on palpation and sometimes shows reddish or bluish discoloration on the overlying skin. The diagnosis is confirmed by histopathologic examination. Radiologic evaluation is little diagnostic and fine needle aspiration biopsy often misdiagnose because both tissues from basaloid cell component and shadow cell component should be obtained for correct diagnosis. And Otolaryngologist should consider the possibility of philomatricoma when childhood or early adulthood persion visits with hard, supferficial mass on the parotid or cheek area. The treatment of choice is surgical excision with clear resection margin. In many instances, overlying skin excision is needed. We report 4 cases of philomatricoma arising from preauricular, cheek and posterior neck.

Reports of ingested foreign bodies migrating to the neck are rare. We encountered a case of fish bone that migrated out of the upper digestive tract to the thyroid gland. This foreign body was identified by computed tomography and ultrasonography about two weeks after onset, and successfully removed via neck exploration and the patient recovered well.

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：Peripheral nerve sheath tumors(PNSTs) are uncommon neoplasm in the head and neck region. The treatment of PNSTs is surgical removal, but excision cause neurologic complications. This study was performed to evaluate the proper diagnosis and treatment of PNSTs with our experiences. Subjects and Method：During the period from October 1994 to July 2007, 58 patients were diagonised with PNSTs in head and neck region. We reviewed medical records and imaging study retrospectively. Result：95%(55/58) of the PNSTs in head and neck were benign；5%(3/58) were malignant peripheralnerve sheath tumors(MPNSTs). 63%(37/58) were neurilemoma, 20%(17/20) were neurofibroma, 2%(1/58) was perineuroma. 55 patients underwent surgery. 80%(45/55) of cases were treated with excision. Enucleation was performed in 7(14%) patients. All cases of benign neurogenic tumors showed no recurrence. Among 3 of MPNSTs 2 patients were Von Recklinghausen’s disease and expired with regional recurrence and lung metastasis. Conclusion：The benign PNSTs can be treated with enucleation if possible and observation can be another choice to minimize neurologic sequele.
