Esophageal Plexiform Schwannoma
We report a patient with a plexiform schwannoma located in the cervical part of the esophagus. A large pedunculated intraluminal polyp, originating in the postcricoid region and protruding into the oropharynx, was found in association with multiple submucosal nodules. Both the intraluminal polyp and submucosal nodules consisted of cellular schwannomatous tissue. The patient showed no signs of neurofibromatosis or schwannomatosis. Plexiform schwannomas are uncommon tumors, mainly confined to the dermis and subcutis of trunk, head, and neck region and upper extremities. Visceral examples are vanishingly rare, and a location in the esophagus has not yet been described. The intruiging mode of presentation in the present case, mimicking that of so-called giant esophageal fibrovascular polyp, probably relates to mechanical factors inherent to the unique esophageal location, Int J Surg Pathol 8(4):353-357, 2000
