Malignant change of dermoid cysts of the ovary. Report on an adenosquamous cell carcinoma and a clear cell carcinoma.
Five cases of malignant change of ovarian dermoid cyst are presented. Two of these cases were of special interest due to the unusual nature of the malignancy. One case (an adenosquamous cell carcinoma) was apparently a malignant change of the columnar epithelium and its squamous metaplasia. The other case (a clear cell carcinoma) appeared to represent coincidental development of two tumors.
