Introduction: The mature cystic teratoma of the ovary is the most common type of ovarian germ cell tumor. Despite the fact that they are typically benign, malignant transformation is a rare but well-documented phenomenon that occurs in roughly 1-2% of cases. The development of squamous cell carcinoma from an advanced cystic teratoma has been reported in the literature. Case presentation: We present a case of a 68-year-old post-menopausal female who was incidentally discovered in an endocrin consultation with a right pelvic mass. According to histopathological diagnosis, squamous cell carcinoma arising in a mature cystic teratoma is diagnosed as a reason for the mass in the right adnexa of the patient. Conclusion: Squamous-cell carcinoma that develops in an advanced cystic teratoma is a rare condition for which there is no research to guide medical care. Clinical trials might assist clarify the best treatment options for patients with secondary squamous-cell carcinoma of the ovaries with such a system and the improvement of therapeutic hypotheses.
