Lobular carcinoma left breast

Case contributed by Dr Garth Kruger

Presentation

Routine screening mammogram

Patient Data

Age: 60
Gender: Female
Modality: Mammography

Subtle parenchymal density deep in the breast just medial of the breast equator.

Case Discussion

This density was on two previous mammograms. It had increased slightly in volume. Workup showed an ultrasound visible mass: diagnosis lobular carcinoma.

Do not leave these densities without workup. Compare with the oldest previous you have and make sure your PACS is programmed to do just that. These lobular cancers can show little change year on year.

We know we miss lobular cancers in large series of screening studies. They do not behave like the typical IDC, very little scirrhous reaction and the asymmetry in density can be really subtle. High index of suspicion is key. Read your screening studies in an isolated environment without you iPhone.
