The first report of bilateral retropharyngeal lymph node metastasis from papillary thyroid carcinoma and review of the literature.
Summary of "The first report of bilateral retropharyngeal lymph node metastasis from papillary thyroid carcinoma and review of the literature."
Abstract The sites of lymph node metastasis of papillary thyroid carcinomas are typically the paratracheal and jugular lymph nodes. On the other hand, metastasis to the retropharyngeal or parapharyngeal nodes from papillary thyroid carcinomas is very rare. During the last two decades, limited to cases with a histologically definite diagnosis by surgery, only 39 cases have been reported. All reported cases were unilateral retropharyngeal or parapharyngeal node metastasis except one metachronous bilateral case, and there were no reports of simultaneous bilateral cases within our literature review. We report three cases of retropharyngeal node metastasis from thyroid papillary carcinoma, including a case of bilateral nodal metastasis. Retropharyngeal node metastasis was successfully resected in all three patients by the transcervical approach. As pointed out in past reports, this report also suggests that prior neck dissection and/or metastasis to cervical lymph nodes might alter the direction of lymphatic drainage to the retrograde fashion, resulting in the unusual metastasis to the retropharyngeal lymph nodes, and there is a possibility of a bilateral pattern. Also, it is necessary to consider the possibility of metastasis from a papillary thyroid carcinoma in the differential diagnosis of lymph node swelling in the parapharyngeal space.

Sentinel Lymph Node Biopsy
A diagnostic procedure used to determine whether LYMPHATIC METASTASIS has occurred. The sentinel lymph node is the first lymph node to receive drainage from a neoplasm.
An accumulation of purulent material in the space between the PHARYNX and the CERVICAL VERTEBRAE. This usually results from SUPPURATION of retropharyngeal LYMPH NODES in patients with UPPER RESPIRATORY TRACT INFECTIONS, perforation of the pharynx, or head and neck injuries.
Malignant lymphoma in which the lymphomatous cells are clustered into identifiable nodules within the LYMPH NODES. The nodules resemble to some extent the GERMINAL CENTER of lymph node follicles and most likely represent neoplastic proliferation of lymph node-derived follicular center B-LYMPHOCYTES.
Local Lymph Node Assay
The local lymph node assay (LLNA) is an alternative method for the identification of chemicals that have the ability to cause skin sensitization and allergic contact dermatitis. Endpoints have been established so fewer animals are required and less painful procedures are used.
The historic designation for scrofula (TUBERCULOSIS, LYMPH NODE). The disease is so called from the belief that it could be healed by the touch of a king. This term is used only for historical articles using the name "king's evil", and is to be differentiated from scrofula as lymph node tuberculosis in modern clinical medicine. (From Webster, 3d ed)
BACKGROUND: The purpose of this study was to investigate the incidence of retropharyngeal lymph node (RPLN) metastasis and to explore the associated risk factors using CT and MRI, to direct clinical r...
Retropharyngeal lymph node (RPLN) metastasis of primary head and neck cancer often receives less consideration than lymph node metastasis in the neck. With improvements in imaging techniques and repor...
Lymph node status remains one of most crucial indicators of gastric cancer prognosis and treatment planning. Current imaging methods have limited accuracy in predicting lymph node metastasis. We sough...
There is little data that determine the clinical characteristics of prelaryngeal lymph nodes (PLN) metastasis in patients with papillary thyroid cancer (PTC). The aims of this prospective study were t...

The purpose of this study is to investigate the relevance of sentinel node in endometrial cancer. Sentinel node is thought to reflect the status of lymph node. Only 10 to 20% of women with...
Occult lymph node metastasis is common in micro papillary thyroid cancer. However, the role of lymph node dissection in the treatment of microPTC remains controversial. The investigators w...
RATIONALE: Diagnostic procedures, such as lymph node mapping and sentinel lymph node identification, performed before and during surgery, may improve the ability to detect lymph node metas...
Detection of lymph nodes starting to be involved by cancer spreading from the thyroid gland during operation is useful. It saves the patient from having a second operation to remove these...
