Cystic lymph node metastasis of head and neck squamous cell carcinoma(HNSCC) which presumed to be mainly originated from oropharynx including Waldeyer's ring may present as a benign cystic mass on lateral neck such as branchial cleft cyst. Branchial cleft cyst is one of the most common lateral neck cystic mass which may result in regional infection or lymph adenopathy. Many of previously reported literatures showed the incidence of cystic lymph node metastasis from oropharynx including Waldeyer's ring. Preoperative imaging studies and fine needle aspiration cytology cannot provide the accurate results until excision of cystic mass for the diagnostic or therapeutic purpose. Recently, we experienced the rare case of cystic lymph node metastasis from ipsilateral tonsil, which mimicked infected 2nd branchial cleft cyst. Thus, we reported our experience with presentation of case and review of literatures.

Background and Objectives: The present study evaluated the results of skin prick test using 55 allergens at 20 centers in the Republic of Korea in 2006, 2010, and 2014-2015. The aim was to assess changes in the positive rate of allergens according to temporal, regional, and environmental factors. Materials and Method: In total, 20 hospitals were selected based on the population distribution in the Republic of Korea. A skin prick test panel comprising 55 aeroallergens was distributed to 18 hospitals for this prospective study. The 2006 and 2010 skin prick test results were collected and analyzed retrospectively from 20 hospitals, while the 2014/2015 skin prick test results (from June 2014 to May 2015) were collected prospectively from 18 hospitals. Results: A total of 14,897 SPT test results were analyzed: 4,319 in 2006, 7,431 in 2010, and 1,852 in 2014/2015. The overall rate of skin prick test positivity to more than two allergens was significantly higher in males than females. The positive rates of alder pollens and birch, oak and ragweed pollen positivity were increased in older patients. Several positive rates were increased according to the temperature in spring. The positive rates for beech pollen, birch pollen, hazel pollen, oak pollen, Tyrophagus putrescentiae, mugwort, cat, Acarus siro, Lepidoglyphus destructor and Tyrophagus putrescentiae were significantly increased, while those of Cult rye pollen and dandelion were significantly decreased over the three test periods. The overall positive rate for allergens in Jeju province varied significantly from Seoul and other cities. Conclusion: Change in the positive rate of multiple aeroallergens was evaluated in the Republic of Korea over time. Our findings can be used to recommend aeroallergens suitable for inclusion in skin prick test panels in the Republic of Korea and will facilitate further investigation of changes in the patterns of allergic diseases.

Purpose: This study examined the effects of the forward head posture and tension type headache on neck movement among office workers. Methods: The subjects were 6 male and 21 female patients composed of a forward head posture group, forward head posture group with a tension type headache and a normal group. Each group consisted of 2 males and 7 females. The cranio-vertebral angle of the head and the angle of motion of the neck were measured. SPSS 23.0 was used for data analysis and one-way ANOVA was performed for the mean comparison of the neck movements in the three groups. Results: The participants had a limitation in the movement of all necks between the forward head posture group and forward head posture with tension type headache group compared to the normal subjects. The forward head posture with tension headache group had limited neck extension and lateral bending compared to the forward head posture group. Conclusion: Office workers have limitations in the movement of the neck when they are accompanied by forward head posture and tension headache. In particular, when accompanied with a tension headache, there is a restriction on the neck extension and side bending. This study is expected to provide basic data for the relief of tension headache and the treatment of forward head posture in office workers.

Background and Objectives : The objective of this study was to investigate clinical factors associated with recurrence of nasopharyngeal carcinoma(NPC). Materials and Methods : We performed a retrospective review of 112 diagnosed as nasopharyngeal carcinoma, treated concurrent chemo-radiotherapy(CCRT) and had complete response from March 1, 1995, to March 31, 2012. Results : Of the recurrent NPC patients, patients received 2nd line chemotherapy had more recurrence within 2 years(p=0.010). Especially, patients received 2nd line chemotherapy longer than 4 months tend to have recurrence early(p=0.035). Other factors are not different between recurrent and non-recurrent NPC patients. Conclusion : The presence and the duration of 2nd line chemotherapy are associated with early recurrence.

Background/Objectives: Cancers of the abdominal or pelvic organ rarely metastasize to the cervical lymph nodes. Although it indicates distant metastasis, perceivable prolongation of survival or cure may be possible in selected cases. We sought to identify patients with cervical metastasis from cancers below the diaphragm and identify patients who may benefit from aggressive treatment. Materials & Methods: From 2009 to 2017, patients with pathologically confirmed metastatic cervical lymph nodes originating from below the diaphragm were included for analysis. Patient demographics, cancer characteristics, treatment course, and clinical outcomes were analyzed. Results: 208 patients were identified. Left supraclavicular node (Virchow's node) was the most frequently involved. Irrespective of treatment, survival for uterine cervical and ovarian cancers was significantly longer than that of other primaries. Patients with isolated cervical metastasis (oligometastasis) had significantly longer median survival compared to patients with concomitant bone, lung, brain, and mediastinal metastases. Conclusion: Although cervical metastasis from cancers of the abdominal and pelvic organ represent distant metastasis, patients with uterine cervix and ovary primary and oligometastatic lesions may benefit from aggressive treatment. Prudent patient selection and further investigation is warranted.

Background : The purpose of this study is to review our experience with the variable applications of the facial artery muscolomucosal(FAMM) flap for oral cavity reconstruction following treatment for head and neck malignancies. Methods : We performed retrospect medical record review from January 2012 to June 2013. This flap technique was applied in 3 patients to reconstruct the defects of oral cavity induced by treatment for head and neck malignancies. Results : The defects and fibrosis occurred due to variable causes related to previous treatment for head and neck malignancies such as tumor resection and chemoradiation. Two patient suffered from defect on hard and soft palate and one patient suffered from trismus related to fibrotic scar band. We performed oral cavity reconstruction using FAMM flap even though these all patients had history of neck dissection surgery or radiation therapy. Conclusion : FAMM flap is an ideal option for reconstruction following treatment not only for primary tumor resection but also for defects induced by variable causes. Preoperative radiation and neck dissection surgery, which are previously considered as some challenges, are no longer contraindication in our cases.

Mucinous adenocarcinoma is rarely reported in head and neck region. In other organ, it usually occur in breast, gastrointenstinal tract and so on. The specific histologic findings of mucinous adenocarcinoma are the large amount of extracellular mucin and tumor cell nests such as floating in mucin pool. It may develop rarely in major or minor salivary gland, but only one case of mucinous adenocarcinoma originating from parotid gland was presented in south korea. We report a case of mucinous adenocarcinoma in the tongue base considered to develop from minor salivary gland with a review of literatures.

Neurilemmomas are uncommon benign tumors originating from the schwann cells of various cranial nerves, spinal nerves, and autonomic nerves. About 25% of the disease is found in the head and neck region and the most common single site of origin is known to be the acoustic nerve. However neurilemmomas of the peripheral segment of the lingual nerve are extremely rare neoplasms. We recendy experienced a case of a benign neurilemmoma of the lingual nerve and this case may be the second to be reported in the literature.

Schwannomas are benign tumors arising from the nerve sheaths of peripheral, autonomic and cranial nerves. Between 25% and 45% of all schwannomas occur in the head and neck region but only 4% involve the nasal cavity and paranasal sinus. Moreover, schwannoma of the pterygopalatine fossa is extremely rare. We present a case of schwannoma of the pterygopalatine fossa in a 43-year-old woman. The patient was surgically managed with endoscopic transnasal approach combined with transantral approach. After 16 months, the patient shows no evidence of recurrence.
