Fat necrosis is necrosis affecting fat tissue (adipose tissue). The term is well-established in medical terminology despite not denoting a specific pattern of necrosis. Fat necrosis may result from various injuries to adipose tissue, including: physical trauma, enzymatic digestion of adipocytes by lipases, radiation therapy, hypoxia, or inflammation of subcutaneous fat (panniculitis).

The gross appearance of fat necrosis is as an irregular, chalky white area within otherwise normal adipose tissue.
