However, about 60% of mucosal melanomas arise in the upper aerodigestive tract
, with sinonasal tract accounting for 66%, oral cavity about 25%, and the remaining in the nasopharynx, oropharynx, and larynx; mucosal melanoma represents about 4% of all sinonasal malignancies.
Their topics include the history and classification of nodal level and neck dissections, biological mechanisms of lymphatic spread, modified radical neck dissection, rehabilitation after neck dissection, structures of the neck amenable to ultrasound evaluation, neck dissection for salivary gland malignancies, elective neck dissection for upper aerodigestive tract
cancers, robotic neck dissection: the retroauricular approach, systemic therapies in the management of head and neck cancer, and measuring quality outcome in neck dissection.
The extent of the field may be as large as 7cm around the carcinoma or in oral cancer it may extend not only through the entire upper aerodigestive tract
but also deep into the respiratory system.
(4) Three of these were in the upper aerodigestive tract
. In 1999, Mandell et al compiled reports of eight hypopharyngeal liposarcomas from three studies, all of which were ALT/WDLs; they had a strong male predominance (7/8) and a size ranging from 2 to 14.5 cm.
Studies in humans reveal that particulate matter from air pollution induce immune responses such as long-term inflammatory and oxidative stress in the upper aerodigestive tract
particularly DNA or protein damage including DNA or protein adducts linked to cancer [13, 14].
In 20% of esophageal cancer patients, other malignancies arise in the upper aerodigestive tract
, and in 10%, they occur in the head and neck area [6, 7].

,and inactive aldehyde dehydrogenase-2 in alcoholic Japanese men.
 The concept was first examined in the upper aerodigestive tract
, where multiple primary tumors and local recurrent tumors originated from the anaplastic tendency of multiple cells.
Conclusion: X-ray was not found to be an ideal modality to diagnose fish or chicken bone impaction in the upper aerodigestive tract

(i.e., larynx, pharynx, and esophagus) and skin.
Granular cell tumor (GCT) is a rare lesion of Schwann cell origin which frequently occurs in the upper aerodigestive tract
but can potentially affect all parts of the body, including the skin.
