A Case of Ovarian Glomus Tumor and Literature Review

Abstract

A 42-year-old Chinese female presented with postcoital bleeding and was incidentally found to have a complex mass in the left adnexal region on pelvic ultrasound. A laparoscopic left salpingo-oophorectomy performed showed an 8 cm cystic mass arising from the left ovary with an associated left fallopian tube hydrosalpinx. The mass was composed of epithelioid cells with a vague nested architecture which showed positive smooth muscle actin (SMA) immunohistochemical staining. Features were consistent with a glomus tumor, an extremely rare mesenchymal neoplasm arising in the ovary. Our case is hitherto the largest reported glomus cell tumor of the ovary measuring 8 cm to date. This tumor has uncertain malignant potential requiring close gynecological surveillance.
