Abstract Background Mature Cystic Teratoma (MCT) is a benign tumor that can lead to malignant transformation (MT) in 1–3% of cases. Management of MT is a big challenge for gynecologic oncologists due to the lack of specific diagnostic and treatment protocols. Case presentation We reported two Iranian cases of MT of MCT with two different stages and prognosis. Our both cases presented the same symptoms, including chronic abdominal pain and distention, loss of appetite, and weight loss. In case number 1, despite the large size of the tumor, the disease was at stage Ia and had a good prognosis; while, case number 2 was at stage IIIc of the disease with a poor prognosis. Conclusion The stage of the disease is the most important prognostic factor, and early diagnosis and treatment are very critical for better survival.

Introduction. Malignant transformation is a rare complication of mature cystic teratoma, with squamous cell carcinoma as the most common malignancy (in 75% of cases). In this article we present a case of a well-differentiated squamous cell carcinoma arising in a mature cystic teratoma and discuss the morphological and clinico-pathological features of malignant transformation in teratoma. Case Report. An 80-year-old woman with symptoms of acute abdomen underwent left salpingo-oophorectomy. Gross examination showed a cystic mass measuring 20 cm in diameter, with papillary formation on its internal surface. Histology revealed a well-differentiated squamous cell carcinoma arising in mature cystic teratoma. Squamous epithelium surrounding the tumor was dysplastic. Conclusion. Squamous cell carcinoma in mature cystic teratoma is a rare pathologic event and in most cases it is an accidental pathohistological finding.

ABSTRACT Mature cystic teratoma or dermoid cyst constitutes about 10 to 20% of all ovarian tumors in the reproductive age group. Malignant transformation is seen in these tumors in about 1 to 2%. Squamous cell carcinoma (SCC) constitutes about 75 to 85% of malignant transformation. Imaging characters and serum tumor markers are two important modalities to differentiate benign and malignant lesions. We are presenting a rare case of SCC arising from mature teratoma. The aim of this presentation is to stress on the significance of preoperative risk assessment of SCC in mature cystic teratoma in postmenopausal age group for optimal treatment.
