Abstract:
Uterine collision tumor is a rare pathologic type composed of two or more malignant tumors, with cervical collision tumors being even rarer. The mechanism of occurrence of collision tumors is not clear. We hope to help clinicians and pathologists understand and diagnose this condition. We report a case of a 53-year-old female diagnosed with poorly differentiated squamous cell carcinoma of the cervix through biopsy. After reviewing previous reports on collision tumors in different locations and theiry types in the cervix and uterus, we found that collisions between cervical squamous cell carcinoma and low-grade endometrial stromal sarcoma were rare. Identifying this type of collision tumor may help with future diagnosis and treatment.
