Rare and unusual occurrence of atypical fibroadenoma on ultrasound

The patient was referred for ultrasound of both breasts to evaluate the mass further which revealed a well-defined mass lesion measuring 1.7 2.3 cm located at 9 to 10 O'clock position involving the breast parenchyma in the outer-upper quadrant of right breast approx. 2 cm from the nipple-areola complex with inhomogeneous internal sonographic appearance of the mass lesion and coarsened peripheral rim of dystrophic calcifications (Figure 1A). Colour Doppler ultrasound demonstrated no significant internal vascularity (Figure 1B). Rest of the quadrants of right breast and left breast demonstrated no focal lesions. Both axillae were unremarkable with no evidence of lymphadenopathy.
