Nasopharyngeal carcinomas are epithelial neoplasm derived from nasopharyngeal mucosa. Nasopharyngeal carcinoma involved cervical lymph nodes frequently. However, nasopharyngeal carcinoma with metastatic axillary node after concurrent chemoradiotherapy was reported rarely. We report the patients who was a 34-year-old man diagnosed as nasopharyngeal carcinoma. He was treated by concurrent chemo-radiotherapy. But axillary node metastasis was found after treatment in 2 years. After surgical resection of axillary lymph node, there is no evidence of disease.

Extended lymph node dissection, which includes dissection of the cervical and superior mediastinal nodes[three-field dissection , has been performed to improve the long-term survival since 1982 in Japan. Recently, the 5-year survival rate after three-field dissection has been reported to be better than 40%. During the period, from April to June, 1995, 4 patients among 7 operable esophageal cancer patients underwent subtotal esophagectomy with systematic dissection of regional lymph nodes including superior mediastinal and cervical lymph nodes at St. Mary`s Hospital. The esophagogastric anastomoses were made in the neck and the ascending routes of gastric tube were posterior mediastinal route. The cancer stage of them were stage IIA & IIB and it was possible to operate on a curability II & III basis. The numbers of resected lymph nodes with the three field dissection were 40-55. Postoperative complications were transient recurrent laryngeal nerve paralysis and atelectasis in 2 patients respectively but there was no anastomotic leak nor stenosis.

Lymph node metastasis from bladder cancer mainly involves the external/internal iliac and obturator nodes as the primary lymphatic drainage sites of the bladder, and common iliac sites as the secondary drainage. Lymph node involvement above the diaphragm is rare. Metastasis to the head and neck region is associated with poor prognosis and low survival rate. Herein, we report a case of cervical cutaneous and lymph node metastases in a patient with bladder cancer. This is a rare case of advanced urothelial carcinoma presenting as an aggressive inflammatory process with extensive lymph node involvement, without bony or visceral metastasis.

Histologically proven 465 cases of neck mass in children were analized for the determination of the nature of lesions. Pathologic specimens were obtained during 10 years from January 1981 to December 1989 at Severance Hospital, Yonsei University, College of Medicine. 1) Congenital lesion was most common in neonate(80%) and congenital lesion and inflamatory disease were common in infancy and inflammatory disease was most common in more than one year old children. Thyroglossal duct cyst was most common(35.4%) disease of the congenital lesion. followed by cytic hygroma(34%) and branchial cleft remnants(29.2%). 2) Benign tumors were discovered most frequently in adolescence (55.2%) and thyroid adenoma(23.7%) and epithelial tumor(21.1%) and hemangiomas(19.7%) were most common. Most common malignant tumors were malignant lymphoma (50%) and Hodgkin's disease and were present in the older children. Metastatic cancers were very rare and their primary sites were deductable in all cases. 3) Reactive hyperplasia of lymph node was most common in inflammatory disease(23.7%). Tuberculosis lymphadenitis was more common than nonspecific lymphadenitis. 4) Bilaterality of lesion was commonly seen in malignant disease(41.7%), reactive hyperplasia of lymph node (38.85%) and metastatic disease(33.3%). Size and duration of the masses were not helpful in the differential diagnosis of the cause of the masses. Pediatric neck mass must be evaluated with its characteristics. sites, bilaterality, size and its cange, duration and patient's age but any of these alone cant not be predicted its causes without biopsy or excision. Biopsy or excision can be done with few complication but biopsy of lymph node for diagnosis is carefully made because a large number of lymph node biopsy showed no definite diagnosis in these selected cases of patients.

Whether it is beneficial to dissect level V in papillary thyroid cancer (PTC) patients with positive lateral neck lymph nodes at levels II-IV is still controversial, especially for low risk cases. In this study, we reviewed the medical records of 47 patients who underwent 47 ipsilateral selective lateral neck dissections (levels II-IV) for previously untreated papillary thyroid carcinomas between October 2006 and October 2008 to assist in establishing the optimal strategy for lateral neck dissection in low risk PTC patients with clinically negative level V nodes. All 47 patients were confirmed to have positive lymph nodes pathologically. Seventeen (36.12%), 36 (76.6%), and 34 (72.34%) patients had positive lymph nodes in levels II, III, and IV, respectively. The mean number of pathologically positive lymph nodes was 1.7 in level II, 2.9 in level III, 2.8 in level IV. No death and distant metastasis were recorded during follow up period. Just 2 patients exhibited recurrence to lymph nodes, and only one showed nodal recurrence in ipsilateral level V, who had positive lymph nodes in all of levels II, III, and IV at initial neck surgery. In conclusion, for PTC low risk patients with clinically negative lymph nodes in level V, non-performance of level V dissection would still achieve good survival results as traditional modified radical neck dissection, with a "wait and see" strategy to be recommended.

A 60 years old female patient presented with $8{\times}6\;cm$ sized painless oval mass in the left parietal region. She had left lobectomy of thyroid gland 10 years ago. Cranial CT, MRI, FGD PET-CT showed a solid mass which invaded left parietal bone. After embolization, craniectomy with tumor excision was performed. Histological examination revealed metastatic follicular cancer originated thyroid gland, with vascular and dura invasion. Postoperatively, neck CT showed right thyroid multiple nodules and right level III multiple lymph node enlargement. Thyroid function test was normal, but level of thyroglobulin was high (72ng/ml). So she had right lobectomy of thyroid gland with lymph node dissection under a diagnosis of follicular carcinoma. But histological examination revealed adenomatous hyperplasia and not lymph node metastasis. After operation, she received radioiodine therapy of 150mCi and then the level of thyroglobulin normalized (8.4ng/ml). The patient is under follow-up since she had operation 4 months ago.

Rhabdomyosarcoma (RMS) is an aggressive and fast-growing malignant tumor. RMS predominantly arises in the head and neck of infancy and children. Metastasis is usually via the blood vessel. We report a case of a recurred RMS of the tongue base with the metastasis to multiple lymph nodes in a 37-year-old female. On the follow-up examination using advanced imaging modalities after surgical treatment of RMS, the lymph nodes should be carefully evaluated like in other malignancies, such as a carcinoma, showing frequent lymph node metastasis.

Elective neck dissection (END), provide proper information on nodal status and stage which are significant prognosticator in head and neck cancers with clinically $N_{(0)}$ neck. But there are many controversies for the extents, methods of surgery, moreover, whether normal lymph nodes, local defencer, have to be removed or not. The authors performed 47 END in 39 patients of head and neck squamous cell carcinoma from 1984 to 1989 and a retrospective study of the cases was conducted. Eighteen percent of nodal metastasis and five percent of extracapsular spread were found in END specimens. We concluded that END provide significant information for the management and evaluation of prognosis in head and neck cancer.

Purpose: To evaluate the radial displacement of clinical target volume in the patients with node negative head and neck (H&N) cancer and to quantify the relative positional changes compared to that of normal healthy volunteers. Materials and Methods: Three node-negative H&N cancer patients and five healthy volunteers were enrolled in this study. For setup accuracy, neck thermoplastic masks and laser alignment were used in each of the acquired computed tomography (CT) images. Both groups had total three sequential CT images in every two weeks. The lymph node (LN) level of the neck was delineated based on the Radiation Therapy Oncology Group (RTOG) consensus guideline by one physician. We use the second cervical vertebra body as a reference point to match each CT image set. Each of the sequential CT images and delineated neck LN levels were fused with the primary image, then maximal radial displacement was measured at 1.5 cm intervals from skull base (SB) to caudal margin of LN level V, and the volume differences at each node level were quantified. Results: The mean radial displacements were 2.26 (${\pm}1.03$) mm in the control group and 3.05 (${\pm}1.97$) in the H&N cancer patients. There was a statistically significant difference between the groups in terms of the mean radial displacement (p = 0.03). In addition, the mean radial displacement increased with the distance from SB. As for the mean volume differences, there was no statistical significance between the two groups. Conclusion: This study suggests that a more generous radial margin should be applied to the lower part of the neck LN for better clinical target coverage and dose delivery.
