title: [Abrikossoff's tumor--a rare differential diagnosis in neoplastic lesions of the esophagus].
abstract: We report the case of a 49-year-old male patient who was referred to our department in February 1998. Due to his complaints of dysphagia and retrosternal pain an upper gastrointestinal endoscopy was performed showing a polypoid lesion of the lower esophagus. This lesion presenting with a wide base and indurated surface was removed by endoscopic snare and forceps biopsies. Histologic and immunohistochemical analyses revealed this lesion to be a benign granular-cell tumor (Abrikossoff's tumor) which is considered to be of neuroectodermal origin. Abrikossoff's tumor is a rare differential diagnosis of polypoid lesions of the esophagus.
