title: Deep cervical granular cell tumor: an atypic location suggestive of neurogenic origin.
abstract: BACKGROUND
  Granular cell tumor (GCT), or Abrikossoff's tumor, is usually benign, with predominantly head-and-neck locations. Putative Schwann-cell origin is controversial. Treatment is surgical, due to risk of malignancy.
  
  
  METHODS
  A 41-year-old man presented with benign GCT in one of the deep cervical plexus roots, suggesting neurogenic origin.
  
  
  CONCLUSIONS
  Surgical resection is important. Preoperative diagnosis is hindered by the ubiquity of the lesions and the poor specificity of imaging. Pathologic and immunohistochemical analysis is essential for definitive diagnosis.
