Glomus tumor of the uterine cervix

Two examples of glomus tumors of the cervix that were incidental findings in patients with uterine leiomyomas are described. The first occurred in a 52-year-old woman with two small uterine leiomyomas and an endometrial polyp. The second occurred in a 39-year-old woman with a large uterine leiomyoma. The glomus tumors were located deep in the cervical stroma and were 0.8 and 0.4 cm in maximal dimension, respectively. The tumors were composed of nests or trabeculae of small cells with round or ovoid hyperchromatic nuclei and eosinophilic or clear cytoplasm. The cells closely surrounded slitlike capillaries and were immunoreactive for smooth muscle actin and muscle specific actin. To our knowledge, no similar tumors have been reported in the cervix.
