Summary. We encountered a case of a chronic expanding hematoma (CEH) that occurred bilaterally in the breast regions of a 42-year-old woman approximately 20 years after SBI removal. There have been no other reports of CEH occurring after implant removal. Furthermore, this is also the first case of a CEH that developed bilaterally in the breasts; most reported cases are of a unilaterally developed CEH. A CEH reportedly develops after a long period of time following trauma or surgery. If surgeons encounter an expanding tumor emerging from regions with such a history, they must consider the presence of a CEH even after implant removal, as in the present case. Hematomas caused by trauma or surgery are usually absorbed or are replaced with fibrous tissue. In rare cases, they can chronically increase as CEHs. Herein, we report a case of a CEH that occurred in both breasts approximately 20 years after silicone breast implant removal.
