Learning objectives: Learning Objectives -To review the main characteristics of invasive lobular carcinoma of the breast.   -To show the most common radiological findings (mammography, ultrasound, magnetic resonance) of invasive lobular carcinoma.   -To show the pathological findings of invasive lobular carc[...]

Background: Invasive lobular breast carcinoma (ILC) represents between 5 and 15% of all breast cancer tumors and occurs almost throughout the entire age range of adult women. ILC presents a diagnostic challenge to the radiologist because of its variable presentation on imaging and clinical examination. ILC aris[...]

Findings and procedure details: We reviewed the pathologic and radiological characteristics of histologically proven ILC, attending our Breast Cancer Unit between 2013 and 2015. One hundred and sixty one ILC were diagnosed at our institution: 59 classic, 41 pleomorphic, 13 solid, 7 signet ring, and 3 alveolar. Thirty one cases we[...]

Conclusion: In comparing radiological findings in the five histologic subtypes of ILC, there are differences between classic ILC and the nonclassical variants. Classic ILC most often has subtle radiological findings, like architectural distortion or asymmetric density in mammography and acoustic shadowing on [...]
