It is marked by ulcerations (breaks on the skin or surface of an organ) and necrosis (death of living tissue) and usually presents a foul odor. This kind of lesion may occur in many types of cancer, including breast cancer, melanoma, and squamous cell carcinoma, and especially in advanced disease.

Fat necrosis in the breast occurs around 0.6%, this represents 2.75% of lesions that end up being benign. However, 0.8% of fat necrosis occurs from tumors of the breast, 1–9% occurs in breast reduction surgery. Individuals that are high risk include women around the age of 50yrs along with pendulous breasts. [8]
Caseous necrosis in T.B. is most common site of dystrophic calcification. Liquefactive necrosis in chronic abscesses may get calcified. Fat necrosis following acute pancreatitis or traumatic fat necrosis in breasts results in deposition of calcium soaps. Infarcts may undergo D.C. Thrombi, especially in veins, may produce phleboliths.
