title: Tongue gastric choristoma: failure to localize by technetium-99m pertechnetate scan.
abstract: Congenital rests of gastric epithelium have been reported in a variety of head and neck locations. Presenting symptoms of these lesions range from an asymptomatic cyst to one which is compromising the airway. The true diagnosis is rarely suspected prior to excision. A case of a gastric choristoma of the tongue is presented which was noted at birth as an intermittently bleeding ulcer. Complete excision of the mass was difficult to ascertain due to poor delineation of the tumor margins from the tongue musculature. A postoperative technetium-99m pertechnetate scan failed to demonstrate residual gastric mucosa. Conservative management resulted in only transient healing of the ulcer. Repeat excision demonstrated abundant residual gastric mucosa. Technetium-99m pertechnetate scanning may not be a reliable indicator of ectopic gastric mucosa in the head and neck region.
