Embryonal Rhabdomyosarcoma in the Pelvis of a 22-Year-Old Female: A Case Report

Abstract

Embryonal rhabdomyosarcoma is a rare soft-tissue sarcoma that is responsible for less than 1% of malignancies in the adult population. We present a case of a 22-year-old female with a six-month history of abnormal uterine bleeding that was found to have an exophytic mass within the cervix. Magnetic resonance imaging was performed and revealed a large pelvic mass. Further workup included biopsies and surgical removal of the tumor, leading to the diagnosis of embryonal rhabdomyosarcoma. PET scan showed no FDG-avid malignancy, aiding in the decision-making process for adjuvant treatment to include vincristine, actinomycin D, cyclophosphamide, and mesna. This case is important to document due to the rarity of this disease and to serve as a reminder to gynecologists to consider the addition of rhabdomyosarcoma in the differential diagnosis when evaluating young adult females presenting with abnormal uterine bleeding and a cervical mass lesion.
