Alveolar soft part sarcoma of the uterine cervix in a woman presenting with postmenopausal bleeding: a case report and literature review.

INTRODUCTION
Alveolar soft part sarcoma (ASPS) of the uterine cervix is a rare mesenchymal malignancy that occurs in adolescents and young adults.


CASE REPORT
A 52-year-old postmenopausal woman presented with profuse vaginal bleeding of one month's duration with severe anemia. The pelvic examination revealed a 3 cm mass on the posterior lip of the uterine cervix. On magnetic resonance imaging, the tumor had high signal intensity on T1- and T2-weighted images. A modified radical hysterectomy and bilateral salpingo-oophorectomy were performed. Immunohistochemical staining for TFE3 and electron microscopic examination revealed an ASPS of the uterine cervix.


DISCUSSION
The better prognosis of cervical ASPS, compared to the soft counterparts, may be related to early clinical detection, small size, resectability, and demarcation of the tumor.
