Embryonal rhabdomyosarcoma (RMS) of the cervix is rare and most commonly occurs in the late teens and early 20s. We report a case of cervical embryonal RMS in a 52-year-old woman. This patient presented with an abnormal vaginal bleeding for 2 months and a mass protruding from the introitus, measuring 7 × 6 cm. She underwent radical abdominal hysterectomy with bilateral pelvic lymph node dissection and radical vaginectomy. The fi nal pathologic result was cervical RMS, consistent with the Intergroup RMS study group IIC. Immunohistochemistry was positive for desmin, myogenin, and myogenic diffentiation 1. The patient received conservative management in a convalescent hospital without adjuvant treatment due to cerebral hemorrhage and relapsed septic condition after surgery.Keywords: Embryonal rhabdomyosarcoma; Uterine cervix CASE REPORT Received: 2011. 5.30. Accepted: 2011 Embryonal Rhabdomyosarcoma (RMS) is the most common soft tissue tumor in childhood and young adults. RMS is rare in adults, with soft-tissue sarcomas making up less than 1% of malignancies in adults and RMS accounting for 3% of all soft-tissue sarcomas. In University of Tehran data only 6 RMS were found (0.39%) among the 1,528 patients with genital tract malignancies [1]. In Korea, a total of 8 cases of RMS were reported in young adults but there has been no case in which the patient was older than 40 years. We report a case of cervical RMS in a 52-year-old woman who underwent radical surgery.
Case ReportA 52-year-old multiparous woman presented with vaginal bleeding for several weeks and the feeling of a mass protruding from the introitus for 2 months. She has normal menstrual cycles. The patient was referred to our institute with a suspicion of a cervical myoma. In her medical history, she had been diagnosed with cerebral arteriovenous malformation and treated with embolization and gamma knife surgery a few months prior. On the vaginal examination, a 7 × 6 cm soft pinkish irregular mass arising from the uterine cervix and reaching up to the introitus was seen (Fig. 1). Biopsy was performed and the result was favoring sarcoma, most likely embryonal RMS. Magnetic resonance imaging and F-18 fl urodeoxyglucose (FDG) positron emission tomography/computed tomography also showed a 7 × 6 cm mass arising from the endocervix and protruding outside the vagina cavity to the perineal portion with FDG uptake (Fig. 2). Moreover, parametrial invasion was seen on posterior aspect of the uterine cervix. The serum level of CA-125 was 58.6 U/mL. Other laboratory tests showed no specifi c abnormality. Her height, weight, and body mass index were 156 cm, 53 kg, and 21.8 kg/m 2 , respectively. Based on the results of these imaging studies and the pathologic result of biopsy, the patient was diagnosed with sarcoma of the uterine cervix.
