Müllerian adenosarcoma is a mixed epithelial-mesenchy- mal neoplasm that originates from the Müllerian duct and is characterised by benign epithelial gland and malignant stro-

mal neoplasm that originates from the Müllerian duct and is characterised by benign epithelial gland and malignant stromal components as active participants in the neoplastic process (1). The uterine corpus is the most common primary site but Müllerian adenosarcoma has been reported to arise in the ovary, cervix, vagina, pelvic peritoneum, pouch of Douglas, broad ligament, bladder, and colon (2-5). Although adenosarcomas are generally low-grade malignancies, adenosarcoma with sarcomatous overgrowth is a highly aggressive tumour. These tumours are frequently associated with postoperative recurrence or metastases and a fatal outcome, even in earlystage disease (6). We present a case of Müllerian adenosarcoma located in the pouch of Douglas and report the clinical and pathological findings. This is the second case reported in the literature that was treated by total excision of the tumour, and no recurrence was seen during the subsequent 24-month period.
