Histopathology:
On gross examination, a left ovarian mass measuring11 X 7.5 X 5.5 cm in diameter was identified. Cut section revealed solid and cystic areas containing yellowish serous fluid as well as pultaceous material. A microscopic examination from left ovarian mass showed histomorphological features of undifferentiated carcinoma [Figure-1, A] and squamous cell carcinoma [Figure-2, A and B] arising from mature cystic teratoma pT3N1b (FIGO stage III B). Ovarian surface involvement was not identified. Tumor deposits were noted on the serosal aspect of the left fallopian tube and bladder. Sections from the uterus, contralateral ovary, right fallopian tube, omentum, appendix, and right pelvic peritoneum showed no involvement by carcinoma. Peritoneal fluid cytology was negative for malignant cells. Out of 24 lymph nodes, three lymph nodes were involved by tumor deposit.
