|Patient: 47 year old female|
|History: 47 year old female. Screening breast exam detected a "lump" in breast on the right.|
|Findings: There is a lucent lesion in the right breast with a suggestion of spiculation or cicatrization in the surrounding parenchyma. What is your most likely diagnosis? What is your differential diagnosis?|
| Diagnosis: |
|Discussion: Focal fat necrosis is quite common in the breast. Most commonly it is demonstrated incidentally on mammograms, but it can appear as a palpable, sometimes painful mass with associated skin thickening and retraction. There is frequently a history of trauma to the breast, particularly after surgery, and this form of fat necrosis has been termed "post-traumatic oil cyst". The typical appearance of these lesions is a lucency surrounded by distortion and spiculation (simulating a cancer). Calcification may also be present in fat necrosis. Fat necrosis, per se, has no malignant potential.|
