This leads to crystal formation,
fat necrosis, and inflammation when the fat is subjected to such stresses as vascular compromise or trauma.

Fat necrosis of the breast clinical, mammographic and sonographic features.
Different from the lesions of granulomatous mastitis, the three most common sonogaphic shapes in patients with
fat necrosis was cystic nodules with sharp margins, solid masses with a boundary echo, and complicated echogenicity accompanied with a thick hyperechoic encysted band.
As a result of
fat necrosis, such abscesses may manifest as numerous pockets with multiple, interconnected foci.
One case developed subcutaneous
fat necrosis right flank around the drain site.
Final gross and histologic diagnosis was granulomatous
fat necrosis causing extraluminal obstruction of the colon.
Subcutaneous
fat necrosis of the newborn: a systematic evaluation of risk factors, clinical manifestations, complications and outcome of 16 children.
Histology findings of haemorrhagic infarction and
fat necrosis confirm the diagnosis with the presence of fibrosis indicative of a longer disease process.
The most striking pathologic findings in the excised specimen were seen in the subcutaneous tissue; there was extensive
fat necrosis, with abundant amorphous eosinophilic and amphophilic debris replacing, and interspersed between, adipocytes (FIGURE 3).
Stage 2 is a transitional stage of partial
fat necrosis and focal
Complications, such as fat embolism,
fat necrosis and infection can happen with this procedure.
