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.

It is well established that cervical lymph node metastasis is the base of clinical study on head and neck cancer. But few studies have been reported on lymph node metastasis of head and neck cancer in Korea. We consider it essential that studies on cervical lymph node metastases are conducted on pathologically proven database. Therefore, We must have database and consitent system for documentation and data collection of neck dissection specimen for prospective and retrospective study. Herein, We suggest several points from our experiences performing the proper data collection and documentation of neck dissection specimen.

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.

Warthin's tumor is the second most common salivary gland benign tumor, typically occurring in the fifth to seventh decades of life which shows an indolent feature. It is usually found in the parotid gland but occasionally in extra-parotid locations such as peri-parotid lymph node. However, Report of solitary Warthin's tumor in cervical lymph node is unusual. We here report a case of 72-year-old male with simultaneous malignant melanoma on eyelid and cervical lymph node enlargement in cervical level II area thus mimicking malignancy metastasis. After excisional biopsy under the local anesthesia, pathology was reported as papillary cystadenoma lymphomatosum, which is a histologically pathognomic finding of Warthin's tumor. However, there was no suspicious tumorous lesion in major or minor salivary glands. This case suggests that Warthin's tumor should be considered as a possible pathology in solitary lymph node lesion of neck.

The poor survival rates of patients with carcinoma of a tongue, despite of modern therapy, is well recognized. One of the most important prognostic factors is status of the cervical lymph nodes. There have been a long-standing debate about the treatment of cervical lymph nodes in early-stage tongue cancer. There are two major treatment opinion. The one is surgical excision of primary tumor with prophylactic neck dissection, simultaneously, and the other is to delay the cervical therapy until cervical lymph node is palpable. Recently we have experienced the early cervical metastasis in three patients who had been diagnosed as a carcinoma of the tongue. They were T1, T2 lesion and no palpable node was found. But histopathologic examination showed the occult metastasis or delayed cervical metastasis was occured. By the review of literature and clinical experience, we could conclude the prophylactic neck dissection offers a better chance for success than therapeutic neck dissection of palpable lymph nodes, in case of oral tongue cancer.

Purpose: The present study was aimed to examine the usefulness of 18F-FDG PET/CT in the evaluation of cervical lymph node metastasis in patients with oral cancer. Materials and methods: Twenty-two patients who underwent neck dissection to treat oral cancer were subjected for examination. The cervical node metastasis was evaluated by means of clinical examination, CT scan, PET, and histologic examination. By comparing the results of each examination modality with those of histologic examination, it's sensitivity, specificity, positive predictive value, and negative predictive value were determined. Results: The oral cancer was more frequent in males with a ratio of 2.14:1. The sixth decade showed the highest incidence in age distribution with mean of $56{\pm}16$. Histologic findings showed that squamous cell carcinoma was the most common (15 patients), and mucoepidermoid carcinoma (3), malignant melanoma (2), and adenoid cystic carcinoma and ghost cell odontogenic carcinoma (1 each), in order. In most cases, wide surgical excision of the primary cancer and neck dissection was performed, followed by reconstruction with free flaps when necessary. When comparing the results of each examination modality with those of the histologic examination, clinical examination showed sensitivity, specificity, positive predictive value, and negative predictive value at 11%, 85%, 33%, and 58%, respectively. CT scans showed at 67%, 77%, 67%, and 77%, while $^{18}F$-FDG PET/CT at 78%, 77%, 70%, and 83%, respectively. Conclusions: These results suggest that PET is more useful, compared with clinical examination and CT scans, in the evaluation of cervical lymph node metastasis in patients with oral cancer.

A 8-year-old female Shih-tzu dog (weighting 4.5 kg) with history of both hindlimb lameness and cervical mass was presented to Veterinary Teaching Hospital, Gyeongsang National University. In physical examination, ataxia, kyphosis, back pain and cervical mass were identified. Marked periosteal new bone formation of the fourth lumbar vertebra and soft tissue opacity mass of cervical region were observed in survey radiographs. Transverse computed tomography (CT) scan obtained at the lumbar and cervical lesions shown a well defined multilobulated bony mass and partially destructive lytic lesions the fourth lumbar vertebral body and a enlarged retropharyngeal lymph node with heterogeneous contrast enhancement and moderately enhancing left tonsillar mass. Neoplastic squamous epithelium which have developed vessel and lymphocyte infiltration in surrounding tissue were confirmed based on histopathologic examination. Based on the diagnostic findings the dog was diagnosed as a cervical lymph node metastases of tonsillar squamous cell carcinoma.

Metastases to regional cervical lymph nodes occur frequently in patients with thyroid cancer. The appropriate management of regional lymph node is important to achieve good disease control and to classify risk stratification for adjuvant radioactive iodine. However, there are some occasions that neck dissection is difficult and embarrassing in thyroid cancer. Especially, extensive or unusual nodal metastases bring challenges and makes neck dissection more difficult. Carotid artery management is one of the most difficult procedure in neck dissection. The management of patients who have persistent or recurrent cervical metastasis involving the carotid artery has been controversial and treatment dilemma to the surgeon. Metastasis of well differentiated thyroid cancer to the retropharyngeal lymph nodes is rare but occasionally encountered. The complete surgical excision is usually recommended for retropharyngeal lymph node metastasis of well differentiated thyroid cancer. An extensive mediastinal dissection in advanced differentiated thyroid carcinoma is occasionally required. This paper will review recent reports of management of advanced nodal metastasis of thyroid cancer and share the author's personal experience.
