Abstract

Frequency of Smooth Muscle Tumors and Adenomyosis in Patient with Previous History of Cesarean Section and the Fate of the Cesarean Section Scar: A Long Term Follow-Up Study

Brendan Eklund, C James Sung and M Ruhul Quddus

Leiomyoma and adenomyosis are two common pathologic entities encountered in hysterectomy specimens. It is often speculated, but not confirmed, that repeated injury to uterine wall may initiate smooth muscle proliferation resulting in a smooth muscletumor. Similarly injury to the wall may lead to entrapment of endometrium in muscle layer leading to adenomyosis. To evaluate the above questions and assess the long term morphologic appearance of the C-section scar, 55 consecutive hysterectomies with previous history of C-section and 45 control cases were studied to evaluate the frequency of leiomyoma and adenomyosis. Our findings show no significant statistical difference in the frequency of such lesions between study and control groups in this series. Besides the scar formation, only rare instances of cystic change, osseous metaplasia and abnormal vasculature were noted at the site of C-section incision in the uterus.
