Abstract: Immature teratoma is very rare form tumour accounts 1% of ovarian teratomas. We report one such case in our hospital in a 15 year old young girl who presented with irregular cycles since menarche and abdominal mass noticed recently. Clinically she is found to have palpable mass of 16 weeks size. MRI done showed a large solid and cystic mass of size approximately 15x7x10cm in the left adnexal region. After routine preoperative investigations done which were within limits and she was found to have markedly elevated specific tumour markers, hence she was planned for laparoscopy and proceed. Laparoscopic ally the tumour were looking solid, nodular in consistency occupying the whole of the left adnexal region extending to the right side, therefore it was converted to open procedure. The patient underwent left salpingo Oophorectomy, specimen sent for frozen section, our pathologist involved in the case suggested features suggestive of immature teratoma. We gave saline washing and sent for cytology to look for malignant cells and o mental biopsy were taken too. Histopathology final report revealed Immature Teratoma. Histological grading of the disease were grade –II moderate amounts of immature neural tissue occupying greater than one but less than four low power filed. Additional features included areas showing mature tissue elements skin, adnexal structures, mature brain tissues cartilage. Pathological staging showed tumour limited to one ovary, capsule intact pNx. FIGO STAGE-Tumour confined to ovary, fallopian tube. Postoperatively patient was hemodynamically stable and there were no complications. PET CT was done which showed enlarged FDG avid nodes namely the right and the left upper deep cervical nodes and normal appearing uterus and right ovary. Tumour markers were repeated poster operatively and were found to be within normal limits. Medical oncologist opinion was obtained and the patient was started on chemotherapy. Post chemotherapy period was uneventful and the patient was stable, now on follow up with medical oncology.
