A Rare Case of Squamous Cell Carcinoma Arising in Mature Cystic Teratoma


BACKGROUND: Mature cystic teratoma (MCT) is a common benign adnexal tumor contributing to about 20% of all ovarian tumors, and it may occur in 10–20% of women during their lifetime. Although the nature of MCT of the ovary is benign, about 1–2% of MCT undergo malignant transformation. 


CASE REPORT: Here, we report a rare case of squamous cell carcinoma (SCC) arising in MCT. This one rare case report of SCC arising in MCT showed satisfactory response to adjuvant chemotherapy. Careful routine evaluation is needed for possible recurrency.

CONCLUSION: This patient was found with infiltration to the urinary bladder and concluded as stage IIB; therefore, the surgeon decided to give adjuvant chemotherapy with paclitaxel/carboplatin. After given three cycles of paclitaxel carboplatin chemotherapy the patient showed favorable outcome, as the CT scan evaluation showed no residual mass.
