Midline neck masses have numerous origin and it is important to diagnose correctly for management. A clinical analysis of 29 cases of midline neck masses confirmed by histopathological examination was done retrospectively during the last 5 years. The results were followings; 1) Of 29 cases, thyroglossal duct cyst was most frequent(17 cases, 58.6%) and non-specific lymphadenopathy was the next(4 cases, 13.8%). 2) Midline neck masses were most frequent on the suprahyoid area(12 cases, 41.4%) and hyoid area was the next(7 cases, 24.1%). 3) Two thyroglossal duct carcinoma was included in 17 thyroglossal duct cyst. 4) Seventy percent of thyroglossal duct cyst was present on hyoid and infrahyoid area.

Background: It is necessary to find and develop the effective way of intervention for patients with neck pain, since the neck pain is becoming increasingly common throughout the world. To identify the altered motor control in patient with neck pain would be informative to find and develop the effective way of intervention. Objects: The aim of this study was to review literature regarding the altered motor control in patients with neck pain, measured by using surface electromyography (sEMG), ultrasonography, and functional magnetic resonance imaging (fMRI), and to suggest prospective research work on neck pain. Methods: Case-control (neck pain/healthy) studies published between 2004 and 2015 that investigated neck muscle activation, thickness, cross-sectional area, and fat infiltrate were searched in Scopus, PubMed, and ScienceDirect. Twenty-eight articles were included in this study. Results: sEMG, ultrasonography, and fMRI were used complementarily to investigate the altered superficial and deep neck muscle activation, thickness, cross-sectional area, and fat infiltrate in patients with neck pain. They showed the following altered motor control when compared retrospectively with healthy subjects or during specific functional tasks: (1) increased superficial muscle activation, (2) lesser deep muscle thickness, (3) smaller cross-sectional area of the deep muscle, and (4) greater fat infiltrate in deep muscles. In particular, among the women, the office workers showed higher muscle activation of superficial neck muscles during functional tasks, although they did not have neck pain, than those who were not office workers. Conclusion: Studies revealed that patients with neck pain showed an altered motor control when compared with healthy subjects by using various assessment modalities. Understanding this phenomenon would help researchers design an effective intervention for alleviating neck pain or to evaluate the effectiveness of the intervention. In addition, we recommend that female office workers take measures to care for their necks before developing neck pain.

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.

Warthin's tumor is the second most common tumor of the parotid gland after pleomorphic adenoma. It is well known to occur as bilateral and multiple patterns. The incidence of extraparotid Warthin's tumor (EPWT) is about 2.7% to 12%, peri-parotid and upper cervical area are the most common sites. Warthin's tumor with synchronous intraparotid and extraparotid area is extremely rare, only a few cases have been reported. We report a-71-year old man with unilateral swelling of the parotid area and upper neck, pathologically confirmed Warthin's tumor with literature review.

Epidermal cysts in mouth floor are rare. There could be confusions in diagnosis due to location and low incidence. For diagnosis, imaging study and cytology are necessary. The treatment of choice is complete excision intraorally or externally and the recurrence is rare. Some authors prefer sclerotherapy, but the follow up is necessary for malignant change. We report two cases of epidermoid cyst in submental area excised externally with literature review.

Kimura's disease is a chronic inflammatory disease with unknown etiology. The most common clinical presentation of Kimura's disease is non-tender unilateral mass in the head and neck area, but bilateral involvement has rarely been reported. Histopathological confirmation should be taken for the diagnosis. Various management options are available, including surgical excision, steroid therapy, and radiotherapy. We report a male patient diagnosed as Kimura's disease involving bilateral retro-auricular region. Simultaneous bilateral neck involvement is an extremely rare finding. For cosmetic reasons, the patient was treated surgically, with satisfactory postoperative results. When evaluating patients with mass lesion in bilateral parotid/retro-auricular area, Kimura's disease should be considered as differential diagnosis.

Infantile myofibromatosis is a rare benign neoplasm which is usually found in males. Most cases of the infantile myofibromatosis are discovered before the age of two years and about half of cases are found at muscle, tendon, and soft tissue of head-neck region. However, it is especially uncommon that infantile myofibroma occurs at the pre-auricular area. In current case, we report a twenty two months old male patient with $2.5{\times}1.5cm$ sized pre-auricular mass at right side. It was surgically removed and histologically showed broad bundle of plump myoid spindle cells with eosinophilic cytoplasm and weakly positive smooth muscle actin expression in myoid cells. In three months of follow up, there was no recurrence.

About 20% of non-Hodgkin' lymphoma occur in the extra-nodal region in the head and neck area and more than half of extra-nodal lymphoma in the head and neck area involves the Waldeyer' ring. Malignant lymphoma arising in the parotid glands are relatively rare, although 90% of all salivary gland lymphomas, appear in parotid gland and are classified as extranodal non Hodgkin' lymphoma. We experienced one rare case of non-Hodgkin' lymphoma in the right parotid gland, with a painless swelling of the cheek region as the chief complaint. We treated with CHOP(cyclophosphamide, $750mg/m^2$ i.v. day1 ; doxorubicin, $50mg/m^2$ i.v. day 1 ; vincristine, $1.4mg/m^2$ i.v. day 1;prednisone, $50mg/m^2$ orally days 1 to 5. repeat every 21 days) and Rituximab combination therapy. We aimed to report here one case of non-Hodgkin' lymphoma in the right parotid gland with review of literature.

Cystic hygroma is a special form of lymphangioma. It most often occurs in the neck of children. We observed a 14-year-old male whose chief complaint was a abnormal swelling of the right mandibular angle area. The computerized tomography showed the well-defined nonenhancing cystic mass on right submandibular gland area and anterior triangle of the neck. The histopathologic fidings exhibited the multiloculatedfluid-filled cysts, which are lined a flattened layer of endothelial cells with foci of lymphocytes found lying adjacent to the lining. After evaluation of above findings, the mass was diagnosed as a cystic hygroma in the neck.
