A case of angioleiomyoma in the buccal space

Angioleiomyoma in the buccal space is a less common benign neoplasm. To the best of our knowledge, only two cases have been described. We herein describe a new case of angioleiomyoma in the buccal space of a 45-year-old Japanese woman. No specific features were observed on clinical examination or ultrasonography. With an initial diagnosis of an ectopic lymph node or benign tumor, excision via the oral cavity was performed under local anesthesia. Healing was uneventful. Immunohistochemical examination revealed that the excised specimen was progesterone receptor-positive and estrogen receptor-negative.
