Abstract:

Cervical cancer is the fourth most common cancer among women in the world, with common sites of distant metastasis including the lungs, bones, liver, and brain. Metastasis to soft tissues is very rare. The clinical manifestations of soft tissue metastasis typically present as hard, ill-defined, and poorly mobile masses accompanied by pain, numbness, and muscle weakness. We report a case of a married woman who presented with vaginal bleeding after sexual intercourse for more than a month and was diagnosed with cervical squamous cell carcinoma via cervical biopsy. In August 2023, after excluding surgical contraindications, she underwent radical hysterectomy, pelvic lymph node dissection, and paraaortic lymph node dissection under general anesthesia, followed by postoperative chemotherapy combined with radiotherapy. Five months postoperatively, a subcutaneous mass was found on the left side of the back, and biopsy revealed squamous cell carcinoma, suggesting a cervical origin. Given the progression of the disease, radical resection of the skeletal muscle soft tissue tumor was performed, and the treatment regimen was changed to radiotherapy, immunotherapy, combined with chemotherapy using paclitaxel and platinum-based drugs. As of the last follow-up, the patient′s condition was stable. Soft tissue metastasis of cervical cancer is rare, and the clinical symptoms are often not obvious. Early diagnosis is crucial for the prognosis of patients.
