Abstract

Malignant transformation of a mature ovarian cystic teratoma is the most serious complication of this relatively common neo­plastic lesion. While any constituent tissue of the teratoma can undergo malignant transformation, squamous cell carcinoma repre­sents approximately 80% of those malignancies. Furthermore, the synchronous occurrence of a second malignancy in that setting is extremely rare. Preoperative diagnosis of malignant transformation within a mature cystic teratoma is extremely difficult and poses a great chal­lenge to current clinical surgical practice. The particularly aggressive behavior of this rare tumor, also poses significant surgical managing dilemmas. We present a case report of a premenopausal woman with an invasive squamous cell carcinoma arising in a mature cystic ter­atoma and a synchronous invasive lobular carcinoma of the breast.
