Mixed ovarian epithelial carcinoma with an unusual histological pattern can be very difficult to diagnose and a thorough sampling of the specimen is needed to rule out the presence of a dual neoplasm. This case reports a very unusual case of mixed epithelial tumour, moderately differentiated serous papillary adenocarcinoma and malignant Brenner’s tumour, in a 65 year old female. She presented with a three month history of abdominal pain. Ultrasound of the abdomen revealed an ovarian mass, for which pan-hysterectomy was performed. Extensive sampling of the tissue revealed a dual neoplasm, serous papillary adenocarcinoma (80%) and malignant Brenner’s tumour (20%), with multiple deposits of the former (dominant tumour) on the uterus, the contralateral ovary and on both the fallopian tubes.
