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.
