Maligne sacrococcygeaal teratoom bij volwassen vrouw

Background

Sacrococcygeal teratomas are neoplasms that are ordinarily diagnosed intrauterinely. In case of complete or partial intrapelvic sacrococcygeal teratoma, it may happen that it is only ascertained at a later age.

Case description

During a regular monitoring visit for breast cancer a 58-year-old female reported that she had discovered a swelling at the level of her coccyx. MRI imagery appeared to indicate an ectopic ovary. After resection, it appeared that it was a mature teratoma from which mucinous adenocarcinoma had developed.

Conclusion

Given the risk of malignant deterioration, it is important that sacrococcygeal teratoma be recognized and treated by means of complete resection, including resection of the coccygeal bone.
