Abstract
We report a case of a 37-year-old woman presenting with a 2.8 cm hypoechoic mass in the upper outer quadrant of the right breast. The original core and fine needle aspiration (FNA) at presentation led to the diagnosis of a fibroadenoma, however the cytopathologist noted few atypical cells insufficient for a malignant diagnosis. The mass was found to be enlarged in size at 3.6 cm at a follow up eleven months later. Repeat FNA and core biopsies demonstrated cytologic features of both fibroadenoma (FA) and invasive ductal carcinoma (IDC). Can a fibroadenoma progress into an invasive carcinoma? Or, is the presence of both of these modalities just a coincidence? We report this case with a brief literature review to investigate this phenomenon.
