title: Clear cell carcinoma arising in a cesarean section scar. Report of a case with fine needle aspiration cytology.
abstract: BACKGROUND
  Clear cell carcinoma arising in a cesarean section scar is an extremely rare disease. To the best of our knowledge, there is no published report on the aspiration cytology.
  
  
  METHODS
  A 56-year-old woman presented with a mass in a cesarean section scar. Initially an abdominal desmoid was considered, but the features of fine needle aspiration (FNA) cytology suggested an adenocarcinoma. The resected tumor was histologically composed of clear cell carcinoma showing cystic, solid and papillary patterns.
  
  
  CONCLUSIONS
  FNA cytology of masses arising in a surgical scar can be a useful tool in obtaining an accurate pathologic diagnosis of a malignant neoplasm.
