Esophageal Plexiform Schwannoma.
ABSTRACT 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

ABSTRACT: We report a case of plexiform schwannoma located in the flexor muscles of the forearm in the absence of other signs of neurofibromatosis or schwannomatosis. Magnetic resonance examination revealed a multinodular irregular inhomogeneous mass. Some nodules displayed a peripheral, high intensity rim and a central low intensity (target sign) on T2-weighted images. Pre-operative diagnosis of the rare plexiform schwannoma may be possible with careful imaging examination for the target sign.Skeletal Radiology 01/2004; 32(12):719-23.

ABSTRACT: Schwannoma is a benign neoplasia of the peripheral nerve sheath. Its localization in the gastrointestinal tract, and in particular in the esophagus, is very rare. According to the existing literature esophageal schwannoma has been reported so far only in adult patients. We report the case of an 11 year old patient with neurofibromatosis, type 2, who underwent surgical excision of a plexiform schwannoma of the esophagus.Journal of Pediatric Surgery 08/2009; 44(7):1458-61.
