Miscellaneous: Poster Abstract: Collision tumor of endometrial stromal sarcoma and squamous cell cancer: A rare entity

A collision tumor is defined by the presence of two separate tumors in one organ on gross, microscopic, and immunohistochemical studies and they should be distinguished from malignant mullerian mixed tumors. A 60 year old lady P8L8 presented with blood stained vaginal discharge and post menopausal bleeding. Examination revealed a 1 × 2 cm cervical growth which was reported as squamous cell carcinoma cervix. Imaging revealed myohyperplasia with normal uterine cavity. The patient underwent Type III radical hysterectomy, bilateral salphingo-oophorectomy and bilateral pelvic lymphadenectomy. The uterine corpus revealed 5 cm growth in uterine cavity which was reported as high grade endometrial stromal sarcoma and the cervical growth was non keratinising squamous cell carcinoma infiltrating the former. The lymph nodes, parametria and vaginal cuff were free of tumor. The patient was referred for adjuvant chemotherapy and radiation therapy.
