An esophageal tumor unlike others: The fibrovascular polyp.

A fibrovascular polyp is a rare benign pseudotumor of the esophagus or the hypopharynx. It comes to light through dysphagia and can lead to death by asphyxiation. CT scan and MRI suggest this diagnosis by highlighting a lobed endoluminal tumor primarily composed of adipose tissue and pedicled on a vessel. Anatomo-pathological analysis of biopsies can exclude liposarcoma, the main differential diagnosis. Treatment consists in complete reconstruction by cervicotomy.
