The traumatic pseudolipoma.

A contour deformity, clinically reminiscent of a large lipoma, can develop after a severe shearing-type injury to the upper thigh, hip, or sacrum, particularly in young women. As the injury is rarely dealt with in the first weeks, it usually presents after a deep scar has contracted. At this stage active surgical intervention seriously increases the aesthetic problem. Conservative treatment with massage, pressure, and possibly injection of steroids is more effective. To the best of our knowledge, this condition has not previously been described.
