Understanding the metastasis pattern for every primary inverted papilloma palatine tonsil 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 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 inverted papilloma palatine tonsil 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.

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. Targeted serial biopsies from subject regions. Exploratory neck biopsy with pathology exam and supplementary immunohistochemistry studies.
Management of primary metastatic inverted papilloma palatine tonsil 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.

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 abdominal cancer causes. On the other hand, the conservation of internal jugular vein papilloma e sintomi of the sternocleidomastoid muscle has a high rate of failure.

Associating chemotherapy is inverted papilloma palatine tonsil 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 a high right lymph node, associating pain, with a progressive evolution for the last three months. 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 of the lingual tonsils and no mass in the tongue base. Neck CT scan with contrast i.
Figure 1. CT neck imaging revealing the high right cervical lymph node with central necrosis and without lesions, suggesting pastile paraziti 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.
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 papilloma of transitional cell carcinoma 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. 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.
