Progressive craniofacial bone loss after cosmetic surgery at the forehead.

We present the case of a 59-year-old woman with a history of plastic surgery at the forehead who complained of progressive indentations at the frontal skull. CT and MR scans revealed significant bone thinning, presenting as lytic skull lesions, which progressed over a period of 3 years. Biopsies were obtained from the lytic lesions and histology showed fibrotic tissue, synthetic residue of previous cosmetic procedure, and no evidence of infection or neoplasm.
