Abstract

An angioleiomyoma is a benign tumor derived from the smooth muscle cells of the vascular wall and tends to arise in the soft tissues of the lower extremities. It may rarely arise in the hard palate, and there are a few reports of this tumor accompanied with palatal bone defect. We herein report a case of angioleiomyoma of the hard palate with bone defect in a 79-year-old woman. She had complained of painless swelling of the hard palate. The lesion was a dark purple, elastic soft hemispheric mass, measuring 10mm in diameter. CT and MRI revealed that the tumor was accompanied with palatal bone defect. After biopsy, the tumor was resected under general anesthesia. Histopathologically, the tumor consisted of hyperplastic, mature smooth muscle cells, and included numerous blood vessels with hypertrophic walls and narrow lumens. The histopathological diagnosis was angioleiomyoma. Tumor recurrence has not been observed for over 5years after the surgery.
