A 76-year-old man with sudden dyspnea was admitted to our department. A fleshy mass was visualized in the labial commissure, and the flexible esophagoscopy showed the polyp prolapsed into the oropharynx, partially obstructing the airway. The polyp was encircled with a large oval snare and Endoloop, which was adjusted to stalk-basis before tightening. Pure coagulation was used to transect the lesion, which was then retrieved. The polyp measured 10 x 2.5 cm. To our knowledge, our case is the first large esophageal giant fibrovascular polyps causing sudden dyspnea in the literature that has been resected endoscopically without complications.

Cervical intramedullary schwannomas are extraordinarily rare. Gross total resection is the best therapeutic option for these types of tumors. Although rare, intramedullary schwannomas should be considered as a differential diagnosis of intramedullary lesions since a good prognosis can be guaranteed to the majority of these patients. We present a case of a cervical intramedullary schwannoma surgically treated in a 19-year-old male patient who initially presented with motor neuron disease.
