Leiomyoma of the round ligament in a postmenopausal woman
Abstract
Objective: Leiomyoma of the round ligament of the uterus is a rare condition. We present the first case of a postmenopausal, previously hysterectomised, woman who received combined hormonal replacement therapy and developed a leiomyoma of the right round ligament. Method: In sections of the tumor, immunohistochemical reaction with monoclonal antibodies against smooth muscle actin, desmin, vimentin, estrogen receptor and progesterone receptor was performed. Results: The leiomyoma showed bizarre histologic appearance in absence of mitotic figures and degenerative changes. Leiomyocytes presented a positive immunohistochemical reaction with monoclonal antibodies against smooth muscle actin, desmin vimentin and progesterone receptor in absence of estrogen receptor. Conclusion: Progestin as part of a combined hormonal replacement therapy may play an important role in promoting the development of leiomyoma in hormonal responsive tissue of the round ligament in postmenopausal women.
