polyps are rare submucosal tumours of the esophagus almost always
originating from the cervical esophagus. These are benign but potentially life-threatening lesions. In the past these lesions have been variably classified as “lipomas,” “fibromas,” and “fibrolipomatous” polyps. Site: Usually arise in the proximal esophagus behind the cricoid cartilage, frequently from the upper esophageal sphincter. Age & sex: Most patients are middle-aged or elderly men. Some cases occur in children or infants and in women. Clinical presentation: Presents as a large, pedunculated lesion. Patient usually complains of dysphagia, substernal discomfort, and sensation of a mass. Many fibrovascular polyps have presented as regurgitated masses in the mouth, others have led to airway obstruction as the mass impacted on the larynx. Gross: Soft, long, polypoid lesion usually covered by normal mucosa. The lesion is attached by a pedicle to the wall in the cervical esophagus. The cut surface has a loose, edematous or myxoid look, with white fibrous tissue areas mixed with yellow adipose tissue lobules. Microscopic features: Mixture of normal or near-normal stromal tissues suggests that the fibrovascular polyp is not a neoplasm. It may be an acquired malformation, hamartoma or an unusual form of inflammatory polyp or a lesion related to injury.
