CONCLUSION:
Malignant transformation of mature cystic teratoma into undifferentiated
carcinoma is rare. Post-menopausal women presenting with giant tumors
must raise suspicion for malignancy since preoperative diagnosis is
often impossible. An intraoperative diagnosis aid in the diagnosis and
determine the extent of surgical treatment. Immunohistochemistry can
help differentiate the type of carcinoma, which can further determine
the treatment and prognosis. There are no fixed guidelines for treating
malignant transformation of MCTO; surgery followed by chemotherapy is
usually the standard of treatment. Diagnosis in the early stages
improves survival. Hence, early detection and proper evaluation of the
type of carcinoma can affect survival.
