title: Fine needle aspiration cytology diagnosis of male breast lesions. A study of 185 cases.
abstract: OBJECTIVE
  To study the fine needle aspiration (FNA) cytologic features of male breast lesions and to determine the efficacy of FNA cytology in the diagnosis of these lesions.
  
  
  METHODS
  During a five-year period (July 1988-June 1993), 188 males with breast lesions were investigated by fine needle aspiration cytology (FNAC). Slides were available for review in 185 of these cases.
  
  
  RESULTS
  Gynecomastia was the most common lesion (132 cases), followed by benign tumors and cysts (16 cases), carcinoma (6 cases) and inflammatory lesions (5 cases). In 26 cases the smears were considered inadequate. The cytologic features of gynecomastia included cohesive sheets of bland cells (100.0% of cases), bipolar bare nuclei (76.5%) and columnar cells (38.6%). Mild nuclear atypia was observed in seven cases. The cytologic features consisted of dyshesive groups of ductular cells with moderate to severe nuclear atypia and absence of bare nuclei as well as columnar cells. The benign tumors and cysts included lipomatous lesions (10 cases), spindle cell tumors (3 cases) and epidermal inclusion/pilar cysts (3 cases). Histology was done in 25 cases. Diagnostic accuracy of FNAC for gynecomastia, benign tumors and malignancy was 100.0%, 100.0% and 66.7%, respectively. The only discrepant case was a carcinoma, diagnosed as highly suspicious on the cytologic specimen.
