Abstract
Mature cystic teratoma accounts for 10-20 % of all ovarian tumors. Malignant transformation is very rare in
mature cystic teratoma, its incidence being 1-2% and is commonly seen in post menopausal women with tumor size
larger than 10 cm. Pre-operative diagnosis of this entity is difficult due to non specific clinical & radiological features
and no specific tumor markers. Malignant change occurs either from epidermal or from bronchial lining. Prognosis of
this tumor is poor. We report a case of squamous cell carcinoma arising in a mature cystic teratoma of the ovary in a 55
year old post menopausal women, presenting with abdominal mass & pain. Radiologically she was diagnosed as right
ovarian cyst with uterine fibroids. Abdominal hysterectomy with bilateral salphingo-oophorectomy was performed.
Histopathological examination revealed moderately differentiated squamous cell carcinoma arising from a mature cystic
teratoma of right ovary with involvement of myometrium and lateral wall of cervix. One should be aware of this
condition to avoid it’s under diagnosis when a post menopausal women presents with a large cystic teratoma of the
ovary.
