Epithelioid Glomus Tumor of the Uterine Cervix: A Case Report and Review.

Herein, we report a case of epithelioid glomus tumor involving the uterine cervix. A 67-yr-old woman with a long-standing history of cervical dysplasia underwent cervical conization. In addition to the patient's high-grade squamous intraepithelial lesion, histologic examination demonstrated an incidental, 0.2-cm glomus tumor in the cervical submucosa. The tumor was composed of bland epithelioid cells in scattered nests closely associated with small-caliber blood vessels. Immunohistochemically, the tumor cells were diffusely positive for smooth muscle actin and caldesmon and only focally positive for desmin and CD34. To our knowledge, only 2 similar case reports exist in the literature. The present case is the first cervical case seen with epithelioid features and in association with cervical dysplasia.
