Introduction:
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.
Case Report:
A 41-year-old man presented with benign GCT in one of the deep cervical plexus roots, suggesting neurogenic origin.
Discussion:
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.
