【 摘 要 】
A 55-year-old woman consulted our hospital for an epulis-like small mass in the anterior region of the mandible. A biopsy of the tumor was performed. Histological analysis showed that the tumor consisted of spindle-shaped and polygonal cells with hyperchromatic nuclei, and intracytoplasmic vacuoles and mitotic figures were scattered. Immunohistochemical staining revealed that the tumor cells were positive for factor VIII-related antigen, CD31, αSMA, and vimentin, but negative for pancytokeratins, S100 protein, neuron-specific enolase, and CD56. The Ki-67 labeling index was more than 50%. Based on these findings, a final pathological diagnosis of angiosarcoma was made. The tumor did not invade into the surrounding tissue. The operation was performed with about a 20-mm surgical margin that was negative for tumor invasion. After a 4-year follow-up, no metastatic lesions were found, and the primary site was covered with a partial denture.
