A squamous cell carcinoma and a malignant fibrous histiocytoma developing in a patient with a mature cystic teratoma. Case Reports in Oncology, 10(1), 98-105.1662-6575https://karger.com/cro/article-pdf/10/1/98/2520023/000455912.pdfhttps://hdl.handle.net/11468/13060We present a very rare case of malignant transformation of a benign mature cystic teratoma. The pathology report revealed malignant transformation of both the epithelial and sarcomatous elements of a benign dermoid cyst. To the best of our knowledge, this appears to be the third case of a malignant fibrous histiocytoma and a squamous cell carcinoma developing from a mature cystic teratoma. Malignant transformation of a dermoid cyst is usually diagnosed postmenopausally, but our patient was premenopausal. The etiology and prognosis of malignant transformation of this benign condition remain unknown.eninfo:eu-repo/semantics/openAccessCystic teratomaFibrous histiocytomaSquamous cell carcinomaArticle10198105WOS:0003964267000142-s2.0-850190481832820317110.1159/000455912Q3N/A
