Background: Mean platelet volume (MPV) is a marker which has been investigated in many cancers but data for head and neck lesions are limited. We aimed to study the MPV levels in head and neck cancers as a diagnostic marker. Materials and Methods: A total of 96 head and neck cancer patients and 31 control patients who did not meet exclusion criteria were enrolled in the study. The cancer locations, the platelet and MPV levels at the first diagnosis time were collected. Results: The head and neck cancer location distribution between these patients was 2 (2.1%) buccal, 9 (9.4%) tongue, 6 (6.3) lip, 1 (1%) gingiva, 1 (1%) hypopharynx, 1 (1%) ear, 58 (60.4%) larynx, 2 (2.1%) maxilla, 2 (2.1%) nasal, 1 (1%) nasopharynx, 2 (2.1%) palatal, 3 (3.1%) primary unknown, 1 (1%) retromolar, 1 (1%) thyroid, 2 (2.1%) tonsil, and 4 (4.2%) salivary gland. MPV levels were significantly different between cancer and control group (p=0.002). The cut-off point for MPV predicting head and neck cancer is >10 fL (sensitivity=55.21, specificity=87.10). Conclusions: MPV level increase, a readily assessable parameter which does not bring extra costs can warn us regarding head and neck cancer risk.

Purpose: Most studies have reported pain in the head-neck and upper-limbs according to smartphone usage, which is related to the proprioception sense in the head and neck, but there have been few studies. Therefore, the aim of this study was identify the adverse effects of the proprioceptive sense in the head-neck according to smartphone usage. Methods: Twenty-seven young adults (male: 9, female: 18) were enrolled in this study. The proprioceptive sense was measured through the joint reposition sense error and neural positon error in the head-neck during smartphone usage for 0, 5, and 20 minutes. The Noraxon MyoMotion system was used to record the joint position angle and neutral positon in the head-neck. One-way repeated ANOVA was used to identify the differences between the three smartphone use durations and the least-squares difference was used as a post hoc test. The data were analyzed using SPSS 18.0 software. Results: The joint reposition sense error and neural positon error in the head-neck were significantly different among the 0, 5, and 20 minutes of smartphone usage (p<0.05). In the post hoc test, the joint reposition sense error and neural positon error showed a significant difference between smartphone use for 0 minute and 5 minute, and between smartphone use for 0 minute and 20 minutes. Conclusion: This study suggests that smartphone use within 5 minutes can have adverse effects on the proprioceptive sense. Therefore, it is necessary to consider the appropriate use time and break time when using smart phones.

Warthin's tumor (WT) is second most common neoplasm in the parotid gland and it can be accompanied by inflammation and necrosis. The chest wall inflammation may present a rapid and fatal clinical course and secondary to parotid abscess is extremely rare. An 81-year-old man came to emergency room complained of rapidly enlarged left parotid mass and inflammatory symptoms and signs around the upper lateral neck. We performed incision and drainage with adequate infection control. He was pathologically diagnosed as abscess. We report the unique and instructive clinical case with a literature review.

Lipoblastoma is a rare benign tumor with 80-90% occurring in children less than 3 years of age and 40% occurring in children less than 1 year of age. The most common site of incidence is limb, and then trunk. Neck is the rare site of incidence. The main symptom that the patient complains about is a rapidly growing neck mass without pain. When the size of mass increases, it can cause dyspnea, Horner's syndrome. Lipoblastoma is usually diagnosed as a lipoma in the fine needle aspiration. Since it is not differentiated from lipoma, liposarcoma, and hibernating adenoma in CT and MRI, the definitive diagnosis is histologic diagnosis through surgical resection. The treatment is complete surgical resection. And recurrence rate is 9-25% due to incomplete resection. Authors report this case with a review of literatures since we experienced a case of lipoblastoma diagnosed histopathologically after surgical treatment of neck mass.

Kimura's disease is a rare disease of unknown etiology, commonly presenting with slow-growing head and neck subcutaneous nodules. It primarily involves the head and neck region, presenting as deep subcutaneous masses and is often accompanied by regional lymphadenopathy and salivary gland involvement. Clinically it is often confused with a parotid tumor or lymph node metastasis. It is difficult to diagnose before surgery, and fine needle aspiration cytology has only limited value. Even though this disease has not shown any malignant transformation, it is often difficult to cope with because of its high recurrence rate. Surgery, steroids, and radiotherapy have been used widely as the first-line recommendation, but none of them is standard procedure until now because of high recurrence rates. The recurrence of the disease reported up to 62%. We recently experienced a case of Kimura's disease, not accompanying peripheral eosinophilia, on the parotid gland treated by surgical resection in an 82-year-old woman with polycythemia vera. Here, we report this case with a review of the literature.

Primary tumors of the parapharyngeal space are rare and account for only 0.5% of head and neck neoplasm. About 80% of parapharyngeal tumors are benign and 20% are malignant. Parapharyngeal space is classified into the Prestyloid space and the Poststyloid space. The Poststyloid tumors are usually benign lesions such as neurogenic tumors, paragangliomas, vascular tumors, or aneurisms. The origins of prestyloid tumors are much more diverse pathology, the pleomorphic adenoma in parotid deep lobe is most common type. Several surgical approaches have been introduced for management of parapharyngeal tumor, such as transcervical, transparotid-transcervical and the transcervical-transmandibular approaches. This paper is aimed to present a large parapharyngeal space tumor removed via transoral approach. It is possible to remove easier by using microdebrider. The pathologic diagnosis was pleomorphic adenoma.

We present a metastatic carcinoma from the breast to the neck soft tissue around common carotid artery, with a rare finding of voice change. A 60 year-old female patient presented with voice change for 7 months. Neck ultrasound revealed a soft tissue mass between internal jugular vein and common carotid artery. Result of fine needle aspiration biopsy was a metastatic carcinoma. Computed tomography and magnetic resonance image revealed $2.5{\times}3.0cm$ sized irregular marginated soft tissue mass in right lower neck encasing common carotid artery and internal jugular vein. Surgical resection was performed and pathologic result with immunohistochemical analysis confirmed the diagnosis of a metastatic invasive ductal carcinoma originated from breast.

Hypopharyngeal cancer usually has invasiveness to adjacent tissue and frequent metastasis to cervical lymph node. In addition, because it often accompanies submucosal extension and second primary malignancy, the sacrifice of larynx and postoperative radiation therapy had been performed in the past. However, it has been reported that conservative surgery of hypopharyngeal cancer show good functional and oncologic outcome according to the development of diagnostic tool and reconstructive technique. We report a case of hypopharyngeal cancer that received conservative surgery followed radiation therapy and intraoperative radiation therapy for neck recurrence.
