title: [Granular cell tumor of the breast with lymph node neuro-naevic cell inclusions: a double pitfall to avoid].
abstract: OBJECTIVE
  To draw attention to the possibility of simultaneous occurrence of pitfalls in breast pathology.
  
  
  METHODS
  Presentation of a curious case with an association of granular cell tumour of the breast and neuro-naevic inclusions in axillary lymph nodes, first interpreted as metastatic mammary carcinoma.
  
  
  CONCLUSIONS
  Non malignant inclusions in axillary lymph nodes, rare but not unusual, may be erroneously interpreted as metastasis of carcinoma, establishing a wrong diagnosis of malignity in the breast. It is important to recognize this type of lesion and the possibility of their coexistence to correct the diagnosis. An approach to the histogenesis of this lesion is presented.
