[Granular-cell tumor (Abrikossoff's tumor): precise preoperative diagnosis is crucial when for minimally-invasive
History And Admission Findings:
A 38-year-old man was referred to a gastroenterologist because of thoracic pain and dysphagia of uncertain cause.
Investigations:
Endoscopy revealed a centrally depressed, coarse submucosal tumor, 1.0 cm in diameter, in the anterior wall of the esophagus at about 35 cm from the teeth. Button-hole biopsy revealed histologically and immunohistochemically a granular cell tumor (Abrikossoff's tumor), positive for S-100 protein. CT-staging was unremarkable, except for a thickening of the distal esophageal wall.
Treatment And Course:
Minimally invasive submucosal resection was undertaken using the videoscopic/endoscopic rendezvous technique. Histological examination confirmed complete resection of the tumor. The clinical course was uneventful and endoscopy 6 and 12 weeks after the operation showed complete resection of the tumor.
Conclusion:
An exact preoperative diagnosis beyond a mere description of site and morphology, but also providing the histopathological data creates favorable conditions for planning and performing a minimally invasive resection. Submucosal resection with the videoscopic/endoscopic in rendezvous technique offers the possibility of complete resection, which can often not be achieved in a submucosal tumor by only endoscopic resection.
