Fibrovascular polyps of the esophagus are rare benign lesions that arise from the cervical esophagus. Most of them are only diagnosed when their size induces symptoms [1].
Five asymptomatic patients (four women, age range: 26 – 49 years) were found to have esophageal tumors on endoscopy. Histological examination revealed polypoid lesions (0.2 – 0.8 cm) with vascularized loose fibrous shafts, lined by stratified squamous epithelium with preserved maturation, compatible with fibrovascular polyp of the esophagus ([Fig. 1]). All the polyps were solitary, except in one patient who had two polyps ([Fig. 2]). This patient, who had multiple sclerosis, also had a raised 0.5-cm lesion covered by normal mucosa, with central umbilication, in the greater curvature of the antrum, compatible with ectopic pancreas. We removed all the polyps endoscopically using standard forceps ([Fig. 3]).
Fibrovascular polyps of the esophagus are benign tumors composed of fibroadipose tissue and blood vessels and lined by normal squamous epithelium [1] [2]. Almost all fibrovascular polyps of the esophagus arise from the segment just inferior to the cricopharyngeus muscle [3] [4]. They are very rare, representing less than 2 % of all benign esophageal tumors [1]. Of the few more than 100 cases reported in the world literature to date, most were only diagnosed when their size induced symptoms, especially dysphagia [1]. Although fibrovascular polyps of the esophagus tend to be solitary, [3] one of our patients had two polyps. Furthermore, to the best of our knowledge, this is the first report of fibrovascular polyps of the esophagus associated with both ectopic pancreas and multiple sclerosis. The most important point of this report is to emphasize awareness of this diagnosis. Although rare, fibrovascular polyps of the esophagus are the most common benign intraluminal lesions of the esophagus and can be missed on endoscopy. Diagnosing fibrovascular polyps of the esophagus requires knowledge of their appearance and careful scrutiny of the upper esophageal region.
