A case of embryonal rhabdomyosarcoma of the uterine cervix in a middle-aged woman

Embryonal rhabdomyosarcoma of the uterine cervix in an adult female

Embryonal rhabdomyosarcoma (RMS) of the female genital tract is an uncommon malignancy, presenting mainly in the pediatric and adolescent populations, primarily affecting the first two decades of life. This malignancy presentation in adulthood is rare and is seldom seen. The incidence of this tumor affecting adult females is approximately 0.4 - 1%, with the common site being the vagina. This tumor infrequently involves the cervix. RMS has a poor survival rate and once diagnosed, it requires aggressive management by radical surgery accompanied by chemoradiation. We present a case of an anaplastic variant of embryonal RMS of the uterine cervix presenting as a cervical polyp in a 36-year-old female who complained of dyspareunia and post-coital bleeding.

Uterine cervix rhabdomyosarcoma: an uncommon entity in an adult patient

Embryonal rhabdomyosarcoma (ERMS) is a malignant neoplasm mostly affecting the genitourinary system of children and is rarely seen in adults. ERMS in uterine cervix is rare and can be misdiagnosed in adult as adenosarcoma or carcinosarcoma. The use of immunohistochemical staining is highly recommended to make sure that the correct diagnosis is reached. To the best of our knowledge, only seven cases of cervical ERMS in women above the age of 50 have been reported in English literature. Herein, we report a rare case of cervical ERMS in a 50-year-old woman that was initially misdiagnosed as an adenosarcoma.

•Cervical rhabdomyosarcoma does not always present as a cervical mass with vesicles.•Treatment regimens studied in the pediatric population can be used in adults with rhabdomyosarcoma.•More data is needed on outcomes of adult patients treated for rhabdomyosarcoma.

Rhabdomyosarcoma of Cervix: A Case Report

INTRODUCTION

Rhabdomyosarcoma has known as a highly malignant soft tissue sarcoma. It has been the most common soft tissue sarcoma in childhood, accounting for about 3 to 4 % of all cases of childhood cancer. Rhabdomyosarcoma was rare in adults, accounting for 3% of all soft-tissue sarcomas. embryonal rhabdomyosarcoma of female genital tract including uterine cervix in an adult was rare.

CASE PRESENTATION

This study has reported a 33-year-old woman presented with abnormal vaginal discharge. Gynecologic examination revealed a cervical mass with grape- like feature protruding into vagina with posterior- superior vaginal wall involvement. Biopsy has performed and pathologic examination was consistent with embryonal botryoid type rhabdomyosarcoma. She has undergone the staging work up measurements including thoracic computed tomography (CT) scan, abdominopelvic magnetic resonance imaging (MRI), bone scan and bone marrow examination. In exception of abdominopelvic MRI, with 2 suspicious pelvic lymph nodes in addition of cervical mass, all others were normal. Radical hysterectomy with lymph node debulking and ovarian preservation has performed. Final results have shown embryonal botryoid type rhabdomyosarcoma of cervix. ovaries, endometrium, parametrium, and follopian tubes were unremarkable. Pelvic lymph nodes pathology and intraabdominal fluid cytology were negative for malignancy. Lymphovascular invasion was identified. She has advised for adjuvant chemotherapy.

CONCLUSIONS

This case has reminded that embryonal rhabdomyosarcoma could occur in uncommon site and older female. Longer follow up of these cases has required due to lack of survival data for embryonal rhabdomyosarcoma of this site and age group.
