Ovarian squamous cell carcinoma arising from mature cystic teratoma is extremely rare. Our study adds to our understanding of this rare but ominous tumor. Herein we report a case of squamous cell carcinoma in a mature cystic teratoma of the right ovary in a 56-year-old woman presenting with pelvic mass and abdominal pain. Histopathological examination after exploratory laparoscopy revealed squamous cell carcinoma arising from an ovarian mature cystic teratoma with appendix invaded. The patient subsequently underwent complete debulking surgery. Unfortunately, the tumour was refractory to combined chemotherapy with docetaxel and oxaliplatin, the patient refused further treatment and passed away six months after the operation.
