Ultrasound (US: left panel), magnetic resonance imaging (MRI: center panel), and pathological findings (right panel) of case 1 (a, upper line) and case 2 (b, lower line). US and MRI show a localized mass in each case. Partial mastectomy was performed prior to immediate reconstruction using a free dermal fat graft, which resulted in surgical margins that were negative for cancer in both cases (a, b, right panel)
