Mystery within a fibroadenoma

Fibroadenomas (FA) are the most common benign biphasic neoplasms in young women. Occurrences of malignant changes within FA are rare. A 32-year-old female patient presented with a lump in the left breast since 1 month. On clinical and ultrasound examination, patient was diagnosed as having multiple FAs. Cytology revealed atypical cells and excision of the lump was suggested. Histopathological examination (HPE) of the lump diagnosed as infiltrating ductal carcinoma with FA. Patient thereafter underwent modified radical mastectomy and further treatment. Patient remained well on follow-up. The present case highlights the need for extensive sampling on fine-needle aspiration and conscientious search for malignancy during the HPE.
