Facing such a scenario, the only solution is following a sequence of investigations and therapy steps towards a correct and complete diagnosis if possible. We review the current literature data and present a personal case. There are many controversies regarding the primitive metastatic neck lymph nodes related to the optimum management, balanced with benefit for the patient.

Metastatic cancer of the neck
În faţa unui asemenea scenariu, singura soluţie este urmarea unei secvenţe de investigaţii şi de paşi terapeutici pentru un diagnostic corect şi complet, dacă este posibil. În acest articol, trecem în revistă datele actuale din literatură şi prezentăm un caz din experienţa proprie.
Există numeroase controverse privind metastazele primare de la nivelul ganglionilor gâtului, în legătură cu managementul optim, benefic şi pentru pacient.
Cuvinte cheie necunoscut primar metastatic limfatic ganglion Introduction The major aspect influencing the prognosis of patients with carcinomas of superior airways is the status of neck lymph nodes on admission. Regional lymph nodes drainage at the level of head and neck is sequential and predictable.
Understanding the metastasis pattern for every primary site is necessary for establishing the surgical management.

The distribution of neck lymph nodes metastasis could be summarized as following: oral cavity tumors will drain to groups I metastatic cancer of the neck III; masses from pharynx and larynx will go to groups II to IV on the same side; midline tumors present metastatic cancer of the neck risk for metastasizing bilaterally 3.
This pathology is defined as a lymph neck node metastasis with an occult primary tumor.
Taking into consideration the site of the lymph nodes metastasis, the primary tumor has an increased probability of situation as follows: group I in the lower lip and tip of the tongue; group IIA in the palatine tonsils, tongue border; group IIB in the rinopharynx; group III in the pharynx and larynx; group IV in the thyroid, esophagus and lungs; group V in the cavum, lungs, breast and stomach 5.
Usually, the sites for unknown primary tumors are nasopharynx, tongue base and palatine tonsils.
Metastatic cancer lymph nodes prognosis
Cystic metastasis is encountered in cases with primary tumor at the level of the palatine tonsils and thyroid carcinomas. It may be mistaken for brachial cysts 6. Diagnosis principles 7 Complete general exam and head and neck clinical exam.
Endoscopy of the nasal, pharynx and larynx cavities, superior digestive endoscopy and bronchoscopies. CT and MRI scans. Fine needle aspiration or core biopsy.
ENT private eye for unknown primary metastatic lymph nodes
Targeted serial biopsies from subject regions. Exploratory neck biopsy with pathology exam and supplementary immunohistochemistry studies. Management of primary metastatic lymph nodes Current management guidelines rely on fine needle aspiration biopsy of the cervical mass. Unfortunately, this approach is prone to error due to metastatic cancer of the neck level of expertise of the pathology laboratory regarding the cytology diagnosis of malignancy.
Therefore, frequently there is used the excision of lymph node for diagnosis 8.
Metastatic cancer head and neck.
Contrast Metastatic cancer of the neck scan reveals the dimensions, number and extent of lymph nodes metastasis. PET scan may show the primary occult site in a small number of cases. Due to the decreased accessibility metastatic cancer of the neck PET scans alternatively, the case should benefit from whole body CT scan in search for the primary tumor 9. Further investigations are endoscopy under general anesthesia for increased comfort of the patient and the specialist.
Any firm or easily bleeding surface should raise the suspicion of a primary site and these areas should be biopsied.
Metastatic cancer head and neck, Introduction - Metastatic cancer neck
Serial blind biopsies are not recommended due to little probability of identifying the primary site Another supplementary step is the same side tonsillectomy, because the primary tumor may be hidden in tonsil crypts Pathology exam of primitive metastatic lymph nodes Most of the primitive metastatic lymph nodes metastatic cancer of the neck manifestations of squamous cell carcinoma metastatic cancer of the neck reduced levels of differentiation.
The primary tumor may reside in a salivary gland of the upper half of the neck.
Inferiorly it may come from thyroid gland. If cytology reveals melanoma, a thorough analysis of the entire skin is necessary. In case of a lymphoma, open biopsy is necessary for diagnosis certainty Therapeutic management In these cases, with unknown primary site, the therapy decision is based on the site and extension of neck lymph nodes involvement.
Radical neck dissection is the gold standard, in spite of esthetic or functional sequels. The preservation of the 11th nerve reduces the morbidity of the surgery.
On the other hand, the conservation of internal jugular vein or of the sternocleidomastoid muscle has a high rate of failure. Radiation therapy is required in cases metastatic cancer of the neck at least one positive lymph node larger prevenirea helmintului 3 cm.
There must be irradiated both neck sides and the areas with an increased potential risk for primary site.

Associating chemotherapy is required by rupture of the lymph node capsule. Recurring lymph nodes benefit from metastatic cancer of the neck surgery or additional radiation therapy if possible Clinical case presentation We present the clinical case of a year-old patient, chronic smoker and drinker, with a high right lymph metastatic cancer of the neck, associating pain, with a progressive evolution for the last three months.
Open in a separate window Hypopharynx cancer usually occurs in the second half of life, between 50—79 years, more frequent in males.
The initial exam reveals the lymph node pertaining to Va group, associating recurrent right nerve palsy and right hypoglossal palsy. We cannot visualize a primary tumor at this stage. The patient underwent tonsillectomy in childhood, and has minimal hypertrophy metastatic cancer of the neck the lingual tonsils and no mass in the tongue base.

CT neck imaging revealing the high right cervical lymph node with central necrosis and without lesions, suggesting the primary tumor The surgical management of this case consisted in an exploratory right cervicotomy with the dissection of a right lymph node situated behind the jugular vein and infiltrating the vein Figure 2.
