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.

Hamartomas are non-neoplastic malformations or congenital errors of tissue development. Hamartoma is composed by an excessive growth of mature tissue present in wrong proportions and abnormal arrangements. The lesion usually presents as a submucosal mass with ill-defined margins. Hamartoma occurs in all areas of the body, especially in the liver, spleen, kidney and lung. However, hamartoma is very rare in the head and neck. Presenting symptoms of hamartoma are typically vague and nonspecific. Treatment of hamartomas consists of adequate surgical excision. We present a 59 year-old male patient who presented with submental swelling. Malignancy could not be ruled out with preoperative radiologic examination, so surgical excision was planned. The mass was excised with transcervical approach. Histopathologic examination has confirmed the mass as a mucinous gland adenomatoid hamartoma.

Simultaneous second primary tumors are not uncommon in patients with oral cavity squamous cell carcinoma. Many studies have previously shown that oral cavity squamous cell carcinoma patients with simultaneous second primary tumor generally have a poor prognosis. Additionally, the choice of the optimal therapeutic modality for oral cavity squamous cell carcinoma patients who present with simultaneous second primary tumor remains problematic. We reported a case of simultaneous squamous cell carcinomas in mouth floor and esophagus, that multidisciplinary team performed resection and reconstruction simultaneously.

Hemophagocytic lymphohistiocytosis (HLH) is a rare but life-threatening one syndrome of excessive immune activation. This immune dysregulation disorder is prominently associated with cytopenias and combinations of clinical signs and extreme inflammation symptoms. For survival, it is important to diagnose early and treat appropriately. We report a case of 10 years old boy who was admitted to the hospital with a month history of fever and cervical lymph node enlargement. There were signs of hemophagocytic histiocytosis in the lymph node and bone marrow. The etiology, diagnosis, and treatment of hemophagocytic lymphohistiocytosis are reviewed.

The Spindle cell lipoma is a slow-growing benign tumor seen generally in the shoulders, upper back, and back of the neck of male. The Pleomorphic (giant-cell) lipoma is a benign tumor of adipose tissue with atypical histological features. It is mainly seen in the same lesion as the Spindle cell lipoma. The Pleomorphic lipoma is cytogenetically similar to spindle cell lipoma with a consistent loss of chromosome 16q material. For this reason, these two entities are regarded as a similar spectrum in the adipose tumors. Herein, we present a 53-year old man with Spindle cell/pleomorphic lipoma in the lateral neck. Physical and radiologic examinations of the Spindle cell/pleomorphic lipoma in the lateral neck are not specific and preoperative diagnosis is usually difficult. Therefore, clinicians should consider the possibility that Spindle cell/pleomorphic lipoma may occur in the lateral neck mimicking the other more frequently observed lesions.

This study compared the stability of the cervical spine according to the presence of neck pain and deep neck flexor performance. Thirty subjects with neck pain, and thirty subjects without neck pain were recruited for this study. The Cranio-cervical flexion (CCF) test was applied using a pressure biofeedback unit to classify the subjects into four subgroups; no cervical pain and good deep neck flexor performance (NG group), no cervical pain and poor deep neck flexor performance (NP group), cervical pain and good deep neck flexor performance (PG group), and cervical pain and poor deep neck flexor performance (PP group). The head sway angle was measured using a three-dimensional motion analysis system. A 3-kg weight was used for external perturbation with the subject sitting in a chair in the resting and erect head positions with voluntary contraction of the deep neck flexors. A one-way analysis of variance (ANOVA) was performed with a Bonferroni post hoc test. The deep neck flexor performance differed significantly among the four groups (p<.05). The NG group had significantly greater deep neck flexor performance than NP and PP groups. The stability of the cervical spine also differed significantly among the four groups in the resting head position (p<.05). The head sway angle was significantly smaller in NG group as compared with the other groups. The PP group had the greatest head sway angle in the resting head position. However, there was no significant difference in the stability of the cervical spine among the groups in the erect head position with voluntary contraction of deep neck flexors (p=.57). The results of this study suggest that the deep neck flexor performance is important for maintaining the stability of cervical spine from external perturbation.

Acute suppurative thyroiditis is rare, infectious thyroid disorder because the thyroid gland is resistant to infection. We report a 26-year-old man with acute suppurative thyroiditis due to a pyriform sinus fistula. He presented with anterior neck swelling and tenderness for 2 weeks. Antibiotic treatment failed to improve his symptoms and signs. Diagnosis was made by bariums studies, computed tomography scan and endoscopic examination. The pyriform siuns fistula was successfully treated by chemical cauterization, partial thyroidectomy and ligation of fistula tract.

There are various types of malignancy in eyelid, such as squamous cell carcinoma, melanoma, and sarcoma. These malignant tumors have potential of metastasis by regional lymph node drainage. The lymph node around parotid gland has been known as a common site of regional lymph node metastasis. The rarity of malignant tumors in the periorbital area makes it difficult to determine the optimal extent of treatment. We report a case of parotid metastasis after eyelid cancer operation in a 60-year-old man.

The present study was designed to see what the local cooling of different body regions especially head and neck, hands and feet effect physiological responses in cold environment. Four male subjects wore garments covering whole body except face and rested for 20 min and then they rested for 40 min with uncovered head, neck, hands and feet, respectively in a cold environment(10$\pm$1$^{\circ}C$, 50$\pm$5%R.H.) 1. Rectal temperature increased when hands and feet were exposed to cold environment respectively, and when head and neck, hands and feet were exposed to cold environment together. 2. Exposed skin temperatures fell in cold environment. And hands temperature was lower than any other exposed skin temperatures. The hands temperature was significantly lower when head was exposed than when head was covered. And the feet temperature were significantly lower when hands were exposed than when hands were covered. 3. Mean skin temperature was the lowest when head and neck, hands and feet were exposed simultaneously, In conclusion, skin temperatures of extremities were decreased due to exposure to the cold environment. Especially upper extremities were lower than lower extremities by exposed parts of the body. It seemed that the extremities played the role of cold receptors but head and neck didn't. And there were large heat losses from the unprotected head and neck. In cold environment of 1$0^{\circ}C$ , thus, it is suggested for the purpose of thermoregulatory responses that head and neck would be covered and extremities would be exposed, especially upper extremities.
