Discussed is a mature cystic teratoma that was surgically removed from the left ovary, said teratoma containing lactating mammary tissue of a 30-year-old Japanese lady, primigravida and in her 36th gestation week. The tumor measuring 3 X 3 X 3 cm, was accidently found when she underwent a cesarian section. In the lactating glandular tissue of the teratoma, the application of an anti-alpha-lactalbumin serum revealed diffuse and/or reticular cytoplasmic stainings of almost all the luminal cells and secretory materials. Further, myoepitheliall cells were clearly visualized with anti-actin serum. References are made to 2 other case reports of similar tumoral tissue.
