Epithelioid leiomyosarcomas arising from the uterine cervix are extremely rare neoplasms, with only three cases reported in the English literature. Case. A 53- year- old Japanese woman was admitted to our university hospital due to massive vaginal bleeding from a cervical tumor. A total hysterectomy with bilateral salpingooop- horectomy was performed. Histological findings, including immunohistochemical study using desmin, SMA, cytokeratin, S- 100, HMB- 45, vimentin, mela- A, and CD68, led to a diagnosis of epithelioid leiomyosarcoma of the uterine cervix. The patient underwent adjuvant chemotherapy and has been disease- free for over 20 months. Conclusion. Immunohistochemical studies may be needed to differentiate among the alternative diagnoses of malignant melanoma, metastatic carcinoma, and epithelioid sarcoma. Additional cases are needed to develop optimal management strategies and to predict prognosis.展开更多
