Аннотация
BACKGROUND: Aggressive Angiomyxoma (AAM) is a rare mesenchymal tumor characterized by local invasiveness and a high recurrence rate, often arising in the pelvis and perineum.
CASE PRESENTATION: We report a 49-year-old woman presenting with a long-standing pelvic mass. Imaging suggested bilateral ovarian endometriomas and a deep pelvic lesion suspicious for AAM. The patient underwent total hysterectomy, bilateral adnexectomy, and complete resection of a pararectal mass via a pure transabdominal laparotomy, without any perineal incision or manipulation. Histopathology and immunohistochemistry confirmed pararectal Aggressive Angiomyxoma coexisting with bilateral ovarian endometriotic cysts.
CONCLUSION: This rare combination highlights the importance of MRI in preoperative diagnosis and the challenges of surgical management for deep pelvic AAM. Complete resection and long-term follow-up are essential to reduce recurrence.
