Giant fibrovascular polyp of the esophagus: Case report of a rare tumor

A fibrovascular polyp of the esophagus is a very rare benign tumor in the esophagus and represents less than 2% of all esophageal tumors. These polyps comprise fibroadipose tissues and blood vessels covered by a squamous epithelium. Fibrovascular polyps arise from the esophagus and could develop to a very large size before becoming symptomatic. We report a case of 48 year-old man with a chief complaint of sore throat and abdominal discomfort persisting for 6 months before admission, and worsening over the 10 days before admission. After the first biopsy, the diagnosis was a fibrovascular polyp of the esophagus. However, the clinician suspected the tumor to be malignant, and a second biopsy was therefore performed along with recommendation to perform immunohistochemistry (IHC) staining. The clinician performed a laparatomy with the indication of a malignant esophageal tumor. Microscopy revealed a polypoid mass covered by a squamous epithelium above edematous stroma comprising fat and fibrous tissue and scattered inflammatory cells. The diagnosis was a fibrovascular polyp of the esophagus. The patient eventually died of sepsis after re-laparatomy surgery and because there was leakage in the gastrostomy tube.
