Cytology:

Cytology features:

 ‣ Type of sample:FNAC
 ‣ Site of biopsy:
   • Laterality:Left
   • Quadrant:Upper
   • Localization technique:Palpation
   • Nature of aspirate:0.2 mL of purulent material

Case summary:

Perimenopausal woman presented with left breast pain and swelling. Diagnosed as inflammatory changes in left breast, BI-RADS 2 on imaging and as acute inflammation on cytology.

Learning points:


  • Most breast abscesses are treated without FNAC. Occasionally, when the clinical diagnosis is not obvious, the lesion is evaluated by FNAC. The cytological findings of breast abscess vary with the phase of inflammation (acute versus chronic).
