Carcinosarcoma of the fallopian tube: A rare case with rapid metastases and port-site metastasis

Abstract

Introduction and importance

Fallopian tube cancer, particularly the carcinosarcoma subtype, is a rare malignancy posing diagnostic challenges.

Case presentation

Our patient was an 83-year-old, nulligravida woman, presented to our outpatient clinic with one month of pelvic pain. On examination, a pelvic mass was detected. MRI suggested a cystic tumor in the fallopian tube, and pyosalpinx was initially suspected. Laparoscopic surgery was performed. However, she was later diagnosed with carcinosarcoma of the fallopian tube, according to the pathological diagnosis. The disease rapidly recurred and metastasized, including the development of Port-Site Metastasis (PSM). The patient underwent PSM excision surgery based on her request, which contributed to her mental well-being.

Clinical discussion

Diagnosing fallopian tube cancer is difficult, and there is often a misdiagnosis risk during surgery, leading to potential errors in treatment. MRI can help identify fallopian tubal cancer, but its features can also resemble benign conditions. Factors like infertility and chronic inflammation can increase the suspicion of cancer. Preventive measures for PSM during laparoscopic surgery are crucial. While it's unclear if removing port-site metastases improves the prognosis, it may benefit the patient's mental health.

Conclusion

Our findings underscore the importance of considering the possibility of malignancy when treating tubal tumors. We should take preventive measures for PSM during laparoscopic surgery. PSM excision surgery could be an option to enhance patient's mental health.
