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.
ENT private eye for unknown primary metastatic lymph nodes
Keywords unknown, primary, metastatic, lymph, nodes Rezumat Metastazele primare de la nivelul ganglionilor cervicali sunt definite în contextul unei tumori primare necunoscute de la nivelul tractului respirator superior.
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 to III; masses from pharynx and larynx will go to groups II to IV on the same side; midline tumors present a risk for metastasizing cancer cervical metastasis 3.
Intraductal papilloma pregnancy 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 cancer cervical metastasis tumors are nasopharynx, tongue base cancer cervical metastasis palatine tonsils. 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, cancer cervical metastasis and larynx cavities, superior digestive endoscopy and bronchoscopies.
CT and MRI scans. Fine needle aspiration hpv wart feet core biopsy. 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 the 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. Contrast CT scan reveals the dimensions, number and extent of lymph nodes metastasis. PET scan may show the primary occult site in a small number cancer cervical metastasis cases.
Due to the decreased accessibility to PET scans alternatively, the cancer cervical metastasis 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.
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 are manifestations of squamous cell carcinoma with 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 cancer cervical metastasis. 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 with at least one positive lymph node larger than 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 salvage 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 cancer cervical metastasis high right lymph node, associating pain, with a progressive evolution for the last three months.
Schistosomiasis zambezi river 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 of the lingual tonsils and no mass in the tongue base.
Neck CT scan with cancer cervical metastasis i. Figure 1. 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 cancer cervical metastasis vein and infiltrating the vein Figure 2.

Figure 2. Surgical aspect of the right lymph node behind the internal jugular vein We observed the lymph node necrosis and engulfment of the cranial nerves 11 to 12 and cervical plexus. We performed radical neck dissection modified type I, with the preservation of the 11th cranial nerve Figure 3.
Figure 3. Radical neck dissection modified type I — step by step The pathological exam suggests the diagnosis of invasive squamous carcinoma metastasis, sustained also by immunohistochemistry exam.
Adenopatia metastatică primitivă cervicală din perspectiva medicului ORL
After surgery, the cervical MRI and 4-week PET scan underlined a lesion in the right tongue base, but without clinical correspondence on serial endoscopic exams.
Chronic local pain was controlled with mild antiinflammatory compounds. The oncology committee decided in favor for radiation therapy with associated chemotherapy with percutaneous endoscopic gastrostomy feeding during the treatment.
The case was monitored for 16 months, without the apparition of the primary tumor on cancer cervical metastasis subsequent endoscopic investigations. Discussion In the case of an unknown primary neck lymph node metastasis, it is necessary to perform a complete thorough screening for the primary tumor.
This endeavor is both complex and costly, as the surgeon leaves the comfort of established treatment protocols towards entering the realm of renal cancer on mri therapy. All the aforementioned steps should be followed.
These cases should never be abandoned during oncology treatment as the primary site may become evident even after a number of years from the moment of initial presentation. Our opinion is that these cases are cancer cervical metastasis insufficiently investigated in the initial steps of diagnosis, or the primary tumor is under the current level of diagnostic accuracy of our imaging modalities.
Conclusions Unknown primary neck lymph nodes metastasis represents a fight under time control with a partially invisible enemy.
The correct cancer cervical metastasis of such complex cases should reunite a team of Detoxifiere brasov surgeon, radiation therapist, oncology specialist and the patient himself for cancer cervical metastasis optimum result.
