Abstract:
A rare case of chronic expanding hematoma in the right temporal region that developed into a large mass over the course of 12 years is reported. The patient, who had a history of blunt trauma to her right temporal region at the age of 4 months, noticed a slowly growing mass at the same site over the last few months. Computed tomography revealed a well-circumscribed subcutaneous tumor. The tumor was completely resected. Histopathologically, the diagnosis of chronic expanding hematoma was confirmed.
