Discussion

Ductal carcinoma represents 65-80% of all breast cancers most common in patients over 40 years of age. Approximately 90% is sporadic and 10% is genetic. Clinically, there is a palpable thickening or firm lump on breast examination with abnormality on screening mammogram. The classic appearance is a dense mass with spiculated or microlobulated margins. Commonly there can be associated architectural distortion and calcifications, benign or malignant appearing.

Ultrasound commonly demonstrates an irregular hypoechoic shadowing mass, taller-than-wide and can present with a dilated duct. Color doppler shows hypervascularity with penetrating vessels. Diagnosis is made with core biopsy. Extent of calcifications is important for surgical planning due to possibility of extensive intraductal component.
