“…Collision tumours are more often unilateral, and can vary in size from 2 to 200 cm with a wide age range of 17-66 years. 3 Ovarian neoplasms are classified as epithelial, stromal and germ cell neoplasms according to the cell of origin. Mature cystic teratoma is the most common benign germ cell tumors of the ovaries accounting for about 30-45% of all ovarian neoplasms and 60% of all benign neoplasms.…”

Abstract. Collision tumors, which are characterized by the coexistence of two or more completely distinct and independent tumors in the uterine corpus, are very rare. A collision tumor is mainly composed of two distinct tumor types, epithelial and mesenchymal. To the best of our knowledge, there has only been a single case in which a choriocarcinoma with an endometrial carcinoma were coexistent but histologically distinct. We herein report the first case of a collision tumor in a 52-year-old woman, with a history of two pregnancies and two deliveries. The collision tumor was composed of three histologically distinct neoplasms in the uterine corpus, namely an endometrioid carcinoma, an undifferentiated carcinoma and a choriocarcinoma. The patient underwent hysterectomy, bilateral adnexectomy and pelvic lymph node dissection, followed by six cycles of adjuvant chemotherapy with paclitaxel̸carboplatin due to the high risk of endometrial cancer, and an additional five cycles of chemotherapy with methotrexate, as the β-human chorionic gonadotropin level was beyond the normal range. Following adjuvant chemotherapy, the tumor markers were within normal limits and no relapses of the cancer have been observed during 1 year of follow-up. Diagnosing a collision tumor prior to surgery is difficult if the neoplasms are in close proximity, or if one of the tumors predominates. Careful pathological examination is crucial for accurately diagnosing the neoplasms in a collision tumor and ensuring appropriate management and a favorable prognosis.

“…It is the only case of ovarian collision tumor composed of three different components reported so far [8] . which is mature teratoma, the possibility of tumor collision is great [9] . Some lesions are small in size and prone to misdiagnosis when attached to the teratoma wall.…”

Background: Collision tumor is a clinically rare disease, it is defined as two or more primary tumors from different tissues occurring at the same anatomical site. Ovarian collision tumor is more rare. Case presentation: A patient was hospitalized with a pelvic mass. The CA125 level was 53.46U per milli liter (normal range, 0 to 30u/ml). Another patient was hospitalized with lower abdominal pain and no apparent hormonal abnormalities. Ovarian lesions were found in both patients after examination, and postoperative pathology showed that both patients were ovarian collision tumors. Conclusion: Collision tumor composed of mature cystic teratoma, follicular membranous cell tumor and serous cystadenoma was first reported. The biological behavior of collision tumor is different due to its different components. Accurate diagnosis is of great significance to treatment.
