A case of nodular cystic fat necrosis presenting as highly migrating subcutaneous nodules

Nodular cystic fat necrosis is a distinct benign subcutaneous nodule characterized by encapsulated necrosis of subcutaneous fat in which non-viable adipose cells are pathologically surrounded by fibrous tissue. We report a case of nodular cystic fat necrosis in a 47-year-old woman who presented with a 2-month history of had multiple highly-movable, subcutaneous nodules on bom shins and posterior thigh. There was an absence of any noteworthy trauma history. Each lesion showed a highly-migratory property, and could easily be moved about 10 cm in any direction. Plain film revealed multiple radiopaque nodules on the right shin. Calcification and lipomembranous changes, in addition to typical features, were also found on histopathologic examination.
