Recurrent endometriosis following total hysterectomy with oophorectomy mimicking a malignant neoplastic lesion: a diagnostic and therapeutic challenge.

ABSTRACT

CASE REPORT A woman with a previous hysterectomy and bilateral salpingo-oophorectomy for endometriosis presented with painless vaginal bleeding. Imaging revealed a heterogeneous soft tissue pelvic mass suggestive of a malignant neoplastic lesion. Radical surgery was performed including excision of the pelvic mass and anterior resection of the sigmoid colon. Histopathology revealed endometriosis. CONCLUSION: The risk of malignant transformation and the difficulty in achieving a preoperative diagnosis make radical surgery inevitable in the management of recurrent endometriosis. The use of hormone replacement therapy after bilateral salpingo-oophorectomy for endometriosis remains controversial and requires careful counseling about recurrence and close follow-up.
